Technologies that seemed like something out of science fiction in the recent past are now becoming more and more real. Everything that a couple of decades ago appeared only in science fiction films is gradually coming to life.

The video surveillance industry has also undergone noticeable changes for the better - modern technologies make it possible to implement the full range of capabilities of a conventional video surveillance camera in a miniature housing.

In addition, various spy cameras appeared in the form of buttons, glasses, watches and other human household items. In this article we will examine the various variations of wireless mini cameras for covert video surveillance, which are of greatest relevance today.

Wireless surveillance cameras

Wireless CCTV cameras can be divided into. The former are very susceptible to various distortions and interference. Interference has virtually no effect on the quality of the image received from the second group of cameras, but it can still lead to a loss of radio signal or a decrease in connection speed.

Wireless mini video cameras can connect to the DVR via a radio channel, with a transmission range of up to 50 meters, in the absence of interference in the form of concrete walls, etc.

Digital cameras, like regular cameras, have standard set components: lens, viewfinder, photosensitive element - matrix, body. Manufacturers make some models without frames to reduce their size, but framed models have gained the most popularity due to their wide range of applications.

Among other things, an integral attribute of modern wireless mini cameras is a receiving module that will receive a signal from a video surveillance camera (such cameras are equipped with a radio channel to provide wireless transmission data), cables for connecting to a monitor, computer or TV, and two mains power supplies - one for the camera, the other for the module. Installation and configuration of such a kit can be done by anyone who knows how to use a computer - it does not require special skills or programming knowledge.

Some case models are equipped with interchangeable lenses, which is a definite advantage if you need to change the viewing angle from time to time - by installing a wide-angle lens, you will get a maximum viewing area, and by screwing on a lens with a larger focal length, you will be able to track only a certain object– a car in the yard, etc. The lenses have a threaded connection, so replacing them is not particularly difficult.

Hidden CCTV cameras are powered by a battery, but it is also possible to connect to the mains using. The battery can operate the camera from 1 to 5 hours. Also, depending on the specific model, it is possible to use the built-in battery as a power source.

For shooting at night, like most conventional cameras, miniature wireless cameras are equipped with infrared illumination diodes. This backlight is invisible to the human eye and allows you to shoot in complete darkness with a possible range of up to 10 meters.

In some cases, mini cameras are also equipped with a slot for a Micro SD memory card, which allows you to wireless connection record video on internal storage with further viewing on a computer monitor screen. To save memory, you can use the “motion-based recording” mode - in this case, video recording will be made only after movement occurs in the field of view of the camera lens. Moreover, such a camera, in principle, does not require the presence of wireless connection, which makes it several times cheaper than analogues equipped wireless transmitter, and also thanks to this, it can be easily used as a wireless outdoor mini CCTV camera.

Legality of covert video surveillance

Thanks to its small dimensions, a wireless mini CCTV camera can easily be disguised as interior items, and no one will even guess that they are being watched, but if something happens, know that the law of the Russian Federation prohibits such interference in a person’s personal life without warning, and you may suffer administrative responsibility for such actions. Articles 20.23 and 20.24 of the administrative code of offenses impose a fine for the use of hidden video surveillance or wiretapping, and article 138.1 of the Criminal Code of the Russian Federation prohibits the import of certain devices that are special technical means to the territory of the Russian Federation.

Wireless mini video cameras with internal memory

Wireless mini camera.

Among the large number of various miniature video cameras, one can single out one that has the most compact dimensions and the ability universal use. This is the Ambertek RS101 model.

Wireless mini WiFi cameras

Wireless WiFi mini cameras have the ability to connect directly to the device from which you plan to monitor (mobile phone, computer, laptop, etc.) via a WiFi network, or transmit a signal to the Internet through a router with subsequent online viewing from any device from any point on the globe.

The most important obstacle to signal transmission is walls, so before purchasing them you need to know in advance, or better yet, carefully check whether the WiFi signal strength is enough to carry out what is planned in your particular case, for example, a wireless outdoor camera with WiFi may have serious problems with signal transmission to if it is installed at a considerable distance from the receiver and in the presence of interference in the form of walls, which will be inevitable if it is installed outdoors. In the absence of obstacles, the picture from the camera will be no different from ordinary ones, and the transmission range can be up to 100 meters.

The power source for mini cameras of this group is also a built-in rechargeable battery with the ability to be powered from mains or batteries. In order to set up the camera, you must first connect it to the power supply, then on your mobile phone Android based/ iOS or computer, find the WiFi network of the video camera and connect to it. Most mini cameras for covert surveillance with wifi do not require special installation, which makes setting them up easy and accessible to everyone; some use special application for mobile devices based on Android or iOS, downloading and installing which will also not cause much trouble for the user of gadgets based on operating systems.

When using several miniature WiFi video cameras in different places It is possible to view the image from each of them on one monitor, but this will require special software and a little computer knowledge to understand how to set up such a system.

Mini wifi camera Ai Ball. Price - 7000 rub.

You can buy a SyCloud camera within 8,000 rubles.

Wireless mini web cameras

Nowadays you won’t surprise anyone with miniature ones that easily fit in the palm of your hand, but wireless models may still be a wonder to a person encountering such devices for the first time. Wireless mini web cameras are quite easy to set up: they come with a special receiver that is inserted into USB port laptop/computer, and receives a signal from the camera at a frequency of 2.4 MHz at a distance of up to 100 m. By installing the included software on your computer, you will immediately see the image transmitted by the camera on the monitor screen.

A wireless web camera can be easily installed anywhere in your home, apartment, office, or on a window, for example, to monitor a car in the yard. An accumulator, battery, or electrical network is used as a power source.

To do this, you need to disguise the camera as some kind of interior item, or install it in a secluded, out-of-sight place. But do not forget about the legality of such actions if you are planning to monitor someone, this has already been said above, so we will not repeat it.

Among other things, miniature web cameras are very convenient when used for your own needs, for example, for communicating with friends or family via Skype, or simply for photographing children or home parties, if image quality is not critical to you.

Mini spy cameras

If earlier spy cameras in the form of buttons, watches, glasses, pens were beyond reality, and were shown only in science fiction films about the future, today you can easily purchase such a gadget at a very affordable price.

The market for mini-cameras for covert surveillance has been absorbed by Chinese manufacturers. Today, it is saturated, the assortment is varied, and the prices are not particularly bad. Therefore, if there is a need, it is easy to purchase a mini camera, both in China, via the Internet, and in Russia, in a specialized store.

Scope of application

Camera KPC-S700CP4 KT&C. Price 3500 rubles.

• Covert surveillance of the premises. For example, you want to constantly monitor office employees secretly, so that they do not feel complex from the all-seeing eye of the lens, but work at ease. Then it will be easier for you, as a leader, to understand who really is who.
• Hidden recording of important meetings, especially those that are held confidential for reasons. Especially if you come to a meeting in the meeting room of the host party, which is crammed with hidden video and audio recording equipment. Take a camera with you, disguised as a button or watch.
• Supervision of nanny and housekeeper. If you would like to see what the servants are doing while you are away, then by installing conventional cameras, you will have three problems. Firstly, this will traumatize your employees psychologically, secondly, they will be offended and depressed morally from distrust of them, thirdly, whoever wants to will always find a “dead zone” in your villa and take revenge on full program. Better install hidden cameras.
• Mini cameras are convenient to use as regular cameras if you are not particularly concerned about the quality of the images. You have the opportunity to shoot discreetly, which does not cause embarrassment or aggression to others. This can happen in crowded places: shops, streets, parks, train stations.
• It is very convenient to use hidden mini-cameras at seminars, lectures, press conferences, in order to subsequently familiarize yourself with the material in more detail. Previously, a voice recorder was used for this, but progress does not stop, especially since the speaker often shows slides that he would like to capture.

Peculiarities

The main feature of mini cameras is that they can be used as hidden cameras. Almost invisible are cameras that have a lens with a hole in the “eye of a needle” or those that are camouflaged as cufflinks, buttons, brooches, etc.

Cameras can also differ in the method of data transmission: Wi-Fi, 3G, wired or high-frequency radio. A separate class of cameras is non-transmitting, with content recording on internal memory.

Types of cameras for covert surveillance

Sip-m02w. Price: 2900 rubles

By type, covert surveillance cameras can be divided into wired, wireless wifi or G3, and autonomous.

• Wired. A class of cameras that are installed on a stationary basis indoors. Some time ago they were used as portable ones complete with a transmitter and battery. To do this, I had to use, at a minimum, a man purse. Time has passed, and they remain convenient only for stationary use. Requires 5-12 volt power.
• Wireless Wi-Fi. These devices currently operate via the WiFi protocol, so their transmission range is short, up to 50 meters indoors. But if you use the TRENDnet TEW-OA14DK antenna (14 dBi) for the receiver, then the line-of-sight communication range will be 8 km. This is quite enough to be positioned within view of the window, even at a decent distance to capture information.
• Wireless 3G. This is still a new product. But for those areas where there is 3G coverage, mini-cameras capable of transmitting this signal are the most promising. You can watch the image from them online anywhere in the world on mobile device. But it’s better to buy a 3G modem, insert it into a laptop or PC, and in addition to viewing, record.
• Autonomous, non-transmitting. A special class of cameras that record video to internal memory and are self-powered. This is very convenient because you are not tied to whoever is reading the information. There is one drawback: the lack of an online mode. Until you merge the data somewhere, it remains inaccessible. Well, so what, you’re not doing intelligence work.

Advantages

The main advantage of mini video cameras is their secrecy. And no, because you need to follow someone or film a crime and they won’t notice you. No.

The psychology of most people is structured in such a way that any entry into their personal life, even from a stranger, triggers a defensive reaction. You just watched a group of your friends playing beach volleyball in a relaxed and fun way. Now try approaching them with a regular camera. The game will change. Someone will go into a rage and start playing for the lens, someone will withdraw and start missing serves, one of the girls will start posing, and some young lady will shout: “Put the camera away, you asshole!”

If you film this with a hidden camera, the game will proceed as normal. Then show the video to the whole company. Your friends will love it, except the girl who posed. She will say: “How could you?”

Camera Samllest VD-7501. Price: 4900 rub.

Popular models

Pen with hidden camera and USB input to download videos. Price: 3600 rubles

• KPC-S700CP4 KT&C. Covert surveillance camera, made in Korea with a 4.4 mm cone lens. It has a 1/3″ SONY CCD matrix and generates a color video signal with a clarity of 380 TVL. Convenient for hidden installation in walls and furniture. At correct installation There is a 1.2 mm hole left on the surface for the lens. Has high photosensitivity. But it is equipped only with an analog video output, which significantly reduces the range of application.
• Sip-m02w. High-resolution color camera, similar in design to the previous one, but has a slightly smaller 1.4” matrix. However, it uses more advanced CMOS technology, which compensates for its smaller area. Pinhole 3.7mm lens. Video compression according to the H.264 standard. The camera comes with software to watch videos for Android and iOS devices. That is, you can easily observe on your mobile device what is happening in the camera’s vision area within the range of the WiFi connection.
• Samllest VD-7501. This is a new generation product. The transmission is carried out over a 3G network. You can see everything that this mini camera records anywhere in the world where there is 3G network coverage. The camera allows you to remotely adjust electronic zoom (10x). Can save video to SD card in HD format, but transmit signal in SD format. It consists of two blocks: a miniature camera and a recorder with a transmitter. Supports motion sensor function, so it will not record a picture without movement for hours.
• Pen with camera. Gadgets hidden recording internal memory is difficult to classify. Because they all have approximately the same technical specifications, but different design. Typically, recording quality is limited to the CIF video standard or, at best, PAL; photographs will be obtained in a slightly higher resolution of 1980x1024. The battery will last for 5 hours of continuous recording. To retrieve information, just connect it to your computer like a regular flash drive. They may look like buttons, lighters, flash drives, watches, etc.

Attention. Unauthorized surveillance is punishable by law. There are precedents.

Installation of video surveillance systems

Installation of mini-cameras for hidden surveillance can be permanent or temporary. TO different types installation, a completely different approach. Need to provide good review visibility of the camera, adjust the focus correctly if it is adjustable, and comply with all laws of conspiracy.

Where to install

In order to choose a camera location, it is necessary to determine where the subject or subjects will be located, taking into account the fact that they can sit, stand up and walk. That is, the camera should display as wide a viewing angle as possible. With an ideal camera position, if it is on a wall, there will be an angle of 65-70 degrees between the wall that is below the camera and the imaginary beam from the camera to the eye level of the subject being photographed. We are talking about a standard executive office room approximately 5x8 meters. If the room is larger, the angle changes.

When you install a camera for office surveillance, it is usually installed in the highest position in the corner. This allows you to most fully cover the territory of the room.

In any case, it is necessary to choose a compromise that satisfies the main requirement - legible visibility of faces.

How to install

Almost all mini-cameras for covert surveillance do not have brackets or adjustments for the position and direction of the lens. This means that you will have to set the angle of inclination and come up with fastenings for them yourself. There are known cases when inexperienced would-be masters built cameras into walls, and with every change in the office interior, they knocked them out of the walls to change their location. Don’t be lazy, order a special removable platform from the specialists, with camera angle adjustment.

As a rule, office walls are lined with plasterboard - this is the most convenient place to install a camera with a cone lens.

Purchase

Regardless of where you buy a mini surveillance camera, to begin with, you should clearly understand what kind of camera you need. The designation in the nomenclature “mini video camera for covert surveillance” does not mean that this camera is suitable for your purposes.

How to choose

Decide:

• stationary or portable;
• analog or digital interface;
• wired or wireless communication;
• WiFi or 3G;

Where to buy

There are several sources for purchase:

• specialized stores selling security equipment;
• radio markets;
• domestic online stores;
• Chinese online stores.

Of course, you can buy these devices in China by paying with a card via the Internet. And most likely it will be cheaper. But it can be difficult to find the device you need in non-wholesale stores. Therefore, it is easier to buy the found product in Russian online stores.

What is the price

The cost of such cameras is low, unless we are talking about professional video surveillance equipment, the price of which goes through the roof for thousands and tens of thousands of dollars.

For example, a pen camera with a USB port costs no more than $150. At the same time, the Samllest VD-7501 hidden camera with 3G transmission function will cost you $108 (in China), not including shipping costs.

If you compare the prices of wired cameras, they are approximately the same, and are around $70. At the same time, cameras equipped with a transmitter, such as Sip-m02w, cost 55 dollars in China, and 100 in Moscow.

Legality of installation

With this point, you can cross out everything that was written above. Because in the Russian Federation any covert surveillance is prohibited, except for those who are allowed to do so (special services). This is regulated primarily by Article No. 23 of the Constitution of the Russian Federation, which states complete inviolability of personal life. But this is just a declaration. But Articles 20.23 and 20.24 of the Code of Administrative Violations directly state that in the case of the use or import of covert surveillance and listening devices, the persons responsible for these acts are fined and the equipment is confiscated.

Therefore, everything written above is written for informational purposes, and whether or not to break the law is everyone’s personal choice.

Modern technologies do not stand still and now ordinary people can take advantage of their gifts. The video surveillance industry has undergone tremendous changes over the past decades, and we can use wireless mini cameras for covert video surveillance even in our own homes. From our review you will find out what variations exist similar devices, as well as which models are most relevant.

The main advantage of wireless devices is their size

Why do we need wireless mini cameras for covert video surveillance: types and purposes

The mini CCTV camera, which does not require connecting cables, is mobile. It is used where massive or stationary equipment cannot be installed. In this case, the location of the device may be hidden.

The small-sized device is used in various fields. It is installed in offices, at home, when you need to leave children alone, or with a nanny, or to monitor staff. This is the operating principle for small cameras for covert video surveillance - the sound is transmitted to recording equipment, which provides access for viewing at any time. The structures are connected to the DVR using a radio channel. The possibility of transmitting signals is up to 50 meters. There are framed and unframed models.

The cameras have the following components:

• viewfinder;
• lens;
• housing and matrix as a supersensitive element.

The design involves installing a receiving element that picks up a signal from a video surveillance device. Cables are also required to connect to any type of screen. Installing hidden video surveillance in an apartment is not so difficult. You can do it yourself. No programming knowledge is required.

The systems are powered by a battery. At the same time, you can connect to electrical network using a power supply. When used, the battery will last approximately 2-5 hours. A built-in battery is used as a power source.

The main manufacturer of such equipment is China.

Let's look at the areas of use of such devices:

• recording negotiations and various business meetings, which allows you to record all important details;
• monitoring subordinates;
• supervision of housekeepers and nannies;
• recording press conferences, lectures and seminars, which allows you to carefully study the material in the future;
• recording events during investigations;
• use as a video recorder for vehicles.

Advantages and disadvantages of mini cameras for covert video surveillance

The demand for video surveillance devices forces their manufacturers to create new and improved models, thereby expanding their range. The advantage of mini cameras is their discreet use. They can easily be disguised as a small object.

Here are some advantages of the devices:

• protection of equipment from damage;
• it is possible to create black and white and multi-colored images;
• presence of a reliable case;
• option with sound accompaniment;
• the control zone is unknown to outsiders;
• used for rooms of different sizes;
• With such observation, it is possible to determine the facts of abuse.

Some models are equipped with ultra-sensitive matrices that allow you to get a clear image. The equipment is powered from a battery and mains. Thanks to the high degree of supersensitivity, you can shoot in the dark.

There are also weaknesses:

• not very high quality of pictures;
• high price;
• takes time to install.

Important! Installation of special equipment requires approval from law enforcement agencies.

How legal is it to use covert surveillance?

Let's find out how legal it is to install mini cameras in public places for covert video surveillance. The law prohibits the use of such surveillance. The Code of Administrative Violations contains articles that provide for a fine and confiscation of equipment in case of hidden surveillance. If you are installing such a device, then a special sign should warn you about it. When installing such devices in the office, a special agreement on the collection and use of personal data must be concluded with employees.

However, covert filming in an apartment is quite acceptable if the recording is not planned for distribution. For example, when staff work in the absence of owners.

Types of video cameras for covert video surveillance

Now let’s find out what types of mini cameras are available for hidden video surveillance in an apartment. Here are some varieties:

• Monochrome and color images.
• Built-in models.
• Options without housing.
• Stationary or mobile.
• Different sizes.
• Mains power or autonomous operation.

Built-in products can hardly be distinguished from ordinary objects, since they can be mounted inside them. Mini cameras are placed on clothing or mounted in the ceiling.

The dimensions of wireless mini cameras for video surveillance are no larger than a match head. They are even disguised as a button. For their operation, wireless translators or autonomous sources are used.

Wireless products are especially convenient to use, since their installation does not require hiding the wires out of sight. Wi-Fi radio channels are used to transmit video. A hidden Wi-Fi surveillance camera device transmits a signal to a computer using a router, and the recording is recorded on the hard drive.

When choosing Wi-Fi options, it is recommended to carefully consider parameters such as focal length, capture angle, brightness and playback features. An accumulator or batteries are used as feeding equipment. Modern technologies They also have mini CCTV cameras with recording on a memory card.

Options for wireless mini-cameras with motion sensors contribute to more cost-effective operation. In this case, the card's capacity is consumed in the appropriate mode.

Selection of miniature covert video surveillance cameras: analogue and digital devices

Wireless mini-cameras for hidden video surveillance in the apartment are digital or analog. The operation of analog devices is carried out using terrestrial television. But this technique is not particularly popular, as it is characterized by a significant percentage of all kinds of interference. Even the weather can affect your broadcast capabilities.

If you decide to buy wireless mini cameras for hidden GSM video surveillance, then you, like many users, preferred the option of digital equipment. Devices of this type are installed where available mobile signals. This functional option can be installed outside or inside the house in any season and under any conditions. Remember that the signal speed may be reduced if there are walls in the path between the recording device and the camera.

Installing monochrome Wi-Fi mini cameras for covert video surveillance helps create a clearer picture. At the same time, a small amount of memory is required, which will help you shoot for a long time.

The advantage of digital technology is that even noise cannot affect the image. They can only reduce the transmission speed.

"Spy" mini cameras

Mini-spy cameras are multifunctional equipment. You will need it if you want to obtain evidence of any incidents. Some models are even used in moving objects and can even be installed in cars. Miniature mechanisms are installed in homes where money or important documents are stored.

The product is popular due to the following advantages:

• the equipment also combines the following elements: a voice recorder, a camera and a night vision device;
• the device remains undetected;
• it is possible to create a high-resolution color image;
• can work continuously for two hours;
• Memory capacity varies from 1 GB;
• video has a resolution of 1280*960 pixels;
• use of additional functions.

Criteria for selecting mini devices

Let's find out what you need to pay attention to when buying a wireless hidden Wi-Fi security camera for your home. Prices for equipment depend on its resolution, size and type of camera. An important factor is the sensitivity of the device. It is measured in lux; this indicator reflects the maximum lighting capabilities. For example, for a street in cloudy weather this value is 3.-5 thousand lux, and for interior spaces it is about 150-1000. In general, sensitivity is important when selecting safety equipment.

If you need high-quality equipment, then before buying a wireless mini camera for video surveillance, decide on the viewing angle. The larger it is, the larger the girth area will be. However, this is not a guarantee of picture clarity. But to get a clear image, you should select a narrow viewing angle. Cameras with this angle can be aimed at a wicket or gate. With the help of wide-angle devices, you can inspect fairly large areas.

A necessary factor when choosing cameras is the resolution. The higher it is, the higher quality the image will be.

To provide a large-scale overview of the local area, zoom lenses and additional devices are used. Some models, even with fairly compact sizes, have the ability to create high-quality resolution, which helps to see a person’s face at a distance of 50 meters.

Devices are classified according to the color parameter into monochrome and color. At the same price, monochrome wireless mini cameras for covert video surveillance provide clearer images.

If the equipment cannot be connected to the network, then a variety of batteries are used. The device will be able to actively shoot for about two hours. But if the device is used in surveillance mode, it can be active for up to 400 hours.

You can select a device, taking into account the method of transmitting information:

• cameras that transmit images over Wi-Fi networks, operate in web device mode and send images in real time. But the use of devices is limited to the area where Wi-Fi is available;
• devices with a GSM communication unit are relevant for installation both indoors and outdoors.

It is worth paying attention to additional features. For example, devices with an infrared mechanism are capable of broadcasting video at any time of the day. Infrared LEDs help illuminate the area in front of the camera. If you want to extend the operating time of the device, you need to choose a product with a memory card. The motion sensor helps reduce current consumption.

The price of covert video surveillance devices depends on the model, functionality and performance. Most budget option can be purchased for 1.5-3 thousand rubles. Standby time is at least 200 hours.

Cameras with illumination, recording on a card and with a sound sensor will cost 3-5 thousand rubles.

Installation of hidden video surveillance: connection and installation

After selecting a suitable device, a wireless mini camera with a motion sensor is installed. In this case, installation should be carried out according to the prepared plan in compliance with all connection diagrams. To configure the equipment, a monitor and a wire with connecting connectors are used. With this approach, you can adjust the sharpness of the lens and the correct viewing angle.

In addition, you will need to choose a high-quality DVR. To do this, you need to pay attention to the following parameters:

• number of video and audio channels;
• recording speed;
• recording format.

Installation of a video recorder of hidden mini-video surveillance cameras with a motion sensor is carried out using the installation hard drive, adjusting the contrast and brightness of the device, as well as optimal sensitivity.

When installing video surveillance, it is worth considering a hidden place. This could be some kind of niche in the wall, an insulated loggia or a suspended ceiling. After this, the monitor is connected and recording is turned on.

So, let's look at the main stages of connecting video surveillance devices:

• installation in a pre-selected and planned location;
• connecting cables to recording equipment;
• connection to a special connecting cable;
• connecting the power supply taking into account polarity;
• connecting the monitor to the DVR and then to the network.

To install invisible elements, you can use any household appliances. It is better if these are stationary objects that cannot be moved. hidden camera CCTV for the home can be disguised even in a wall clock. Just remember that the camera body gets hot.

Modern mini video cameras are actually fantastic devices that 10–20 years ago could only be seen in spy films. Some devices easily fit not only in the palm of your hand, but also on one finger of a person. At the same time, they provide very high quality recordings, allowing you to subsequently examine all the details of what is happening.

Camera options
One of the most important characteristics such a device is the type of matrix used in it. When choosing a specific model, it is advisable to pay attention not only to the resolution, but also to the physical dimensions of such a part, as well as the level of photosensitivity. However, the shooting quality of a mini-video camera also depends on other factors - for example, on processor performance, so before purchasing it is advisable to watch several videos obtained using a specific device.
The design of the lens is equally important. The use of optically pure glass and aspherical lenses has a positive effect on the quality of shooting, helping to avoid color shifts, geometric distortions of objects and other interference. It is important to clarify the camera viewing angle, which modern models can vary between 60–180 degrees.

Image stabilization
Since small action cameras are typically used on the move, they need a system that eliminates noise caused by lens movement. Most manufacturers use digital stabilization.
Virtual image shift is not able to completely eliminate distortion, but it does not complicate the design of the device and practically does not increase its cost.
If the user plans to take pictures during extreme sports, he should buy a mini video camera with optical stabilization. In it, the position of the matrix is ​​adjusted by special servos, which eliminates its shift relative to the lens.

Let's take a closer look.

The camera comes in a stylish metal box.

The kit also includes 2 cables - for recharging the built-in battery of the video camera from the computer’s USB port and for viewing (copying) recordings to the computer; a lanyard for wearing the device around the neck and a disc with a driver.

Let’s add on our own: you won’t need a disk at all, since operating system It automatically recognizes the camera when it is connected via a USB port (the memory card must be inserted into the appropriate slot). An additional removable disk will be created, and you can view the contents of the camera as a flash drive.

The chamber is smaller in size than a regular matchbox. It weighs 30 g and this is with a built-in battery. Amazing, isn't it?!

With all this, this device has all the functionality of a regular professional video surveillance camera: recording color video with sound and photos.

On the front side we see a pinhole lens with a diameter of 1 mm!!! above it and slightly to the left there is a small decorative window (it does not carry any semantic meaning). On the left side there is a hole for a lanyard, with which you can wear this miracle of technology around your neck.

There are only two buttons in the upper side part, with their help you can control this tricky device. Why cunning? Yes, because these two buttons perform all operations - turning the power on and off, turning video recording on and off, taking photos and interacting with the computer.
In fact, everything is not as complicated as it might seem at first glance. In addition, the kit includes detailed instructions in Russian, in which you will find comprehensive answers to all questions when operating the device.

On the left side there is a slot for memory cards. We will need cards in microSD format, the maximum volume that the device can accept is 16 GB. The maximum capacity card can record up to 400 minutes of color images with real-time sound in a resolution of 1280x960 pixels.
The final number of hours of video that can be saved on a 16 GB card depends on many factors, such as the brightness of the overall picture being shot, etc.

On the other side we see a mini USB connector. Using the included cables, we can recharge the built-in battery at any time, and we can also connect the camera to view (copy) recordings to a computer (laptop).
It is worth noting that the set includes 2 wires, each of which serves a specific purpose, and there are corresponding labels and stickers on them.
