Small hidden mobile cameras. Mini video cameras. Advantages and disadvantages of mini cameras for covert video surveillance

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 consider 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.

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 learn what variations of such devices exist, as well as which models are the 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 different areas. 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. In this case, you can also connect it to the 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 by 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 places common use for hidden 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.

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 functioning 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 mobile signals are available. 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;
there is an opportunity to create color image With high degree permissions;
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. Important factor– 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 require 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, wireless mini cameras for covert video surveillance of the monochrome type 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 transmitting images via 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 functions. 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. The 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 by installing a 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. A hidden home security camera can even be hidden in a wall clock. Just remember that the camera body gets hot.

The special features of this camera are:
Very small size, a minimum of functional buttons and a high resolution photo and video shooting.

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 camera video surveillance: recording color video with sound and photos.

On 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.
