CCTV cameras: choice of invisible assistants

Full security of the object is provided with the help of equipment for round-the-clock surveillance. The most valuable and effective devices with advanced capabilities are covert video surveillance cameras, which are characterized by compact dimensions, making them invisible to the prying eyes. Such equipment can be used in any field of activity where it is impossible to use a conventional camera.

What are covert video surveillance cameras

Mini-cameras are compact devices designed for video surveillance. According to the principle of operation and design, they are no different from standard models. The camera consists of a body, matrix, lens and processor. Additionally, it can be equipped with a motion sensor, infrared illumination, microphone, memory card, built-in battery. Mini cameras for video surveillance are used to record information in order to save it on a carrier and display it on a monitor.

A CCTV camera should not be located near power sources. The place of installation must be accessible for quick and unobtrusive removal of the device for servicing.

The main advantages of mini-cameras are their compactness, the possibility of flush mounting, and the ability to work offline. However, such devices do not provide the high image quality with detail that is typical for standard size cameras. This is due to the fact that the matrix and the lens have a fixed focal length, as a result of which the image resolution decreases. Poor lighting also affects the performance of hidden mini cameras.

Areas of use of mini cameras for covert video surveillance

Miniature covert surveillance cameras are widely used. They are often installed in offices to exercise secret constant control over personnel, so that such a procedure does not adversely affect performance and employees do not complex.

Installation of covert surveillance is also justified in a home where hired personnel, such as a nanny or housekeeper, work. Conventional cameras will psychologically traumatize workers who are capable of harboring evil and resentment, which can be negatively reflected later.

Miniature cameras are also indispensable for recording business meetings and negotiations, as they allow you to save important information. This is especially valuable if they are held confidentially for certain reasons. They are often used to record seminars, lectures, press conferences in order to further carefully study the material. Mini cameras are justified for capturing events during investigations. Small devices can be used for general shooting if video quality is not too high.

Useful advice! The mini camera can be used for road transport as a video recorder.

What to look for when choosing a hidden mini CCTV camera

When choosing a camera for covert video surveillance, you should pay attention to such device parameters as video quality, viewing angle, sensitivity and resolution.

The supersensitive element is located on CCD devices, so that the matrix can reproduce a color image even at the lowest light level. Many modern camera models automatically switch to monochrome video at zero illumination, which provides a better picture.

Small video cameras for hidden video surveillance are characterized by different viewing angles. They can be divided into telephoto and wide-angle. The first option is currently used extremely rarely, since such models differ in the minimum viewing angle. This parameter is determined by the focal length, which for mini cameras is in the range of 2.7-3.6 mm. These values ​​correspond to a viewing angle of 60-90 degrees.

Important! To obtain a high-quality image, it is important to choose the right place for installing the equipment, in which there will be no optical distortion of the picture.

When choosing a device, the sensitivity and resolution of the camera are of no small importance. The latter parameter can vary between 1.3-12 megapixels. Enough for home video surveillance camera with 2MP resolution. Devices with the maximum value of this parameter have a number of disadvantages, one of which is the recording frequency, which is only 10-15 fps.

You should also avoid choosing high-sensitivity mini cameras. The optimal value is 0.2-0.3 lux. For night video surveillance, it is recommended to give preference to devices with IR illumination, which allows you to get a clear picture at any time of the day.

Varieties of hidden video cameras, their characteristics

Based on the design, the cameras can be boxed or unpackaged. The first option is represented by full-fledged video surveillance devices. Frameless cameras are built into items of clothing, household appliances, interiors and other objects.

Cameras can be analog or digital depending on how they function. Analog devices transmit the image as an electrical television signal. Standalone camcorders do not provide high image quality.Any external influences will cause all kinds of interference. However, such devices are characterized by low cost.

Digital mini-devices are very popular today, which are installed in the place of access of a mobile signal. Once captured, the image is converted into a digital signal that is sent to the server. Such hidden IP cameras allow you to get a high-quality picture with high detail.

Depending on the sensor installed in the camera, the device can transmit a black and white or color image. The first option is characterized by better picture reproduction clarity.

Features of wired and wireless video cameras

According to the method of data transmission, video surveillance devices can be wired and wireless. For the functioning of the first option, it is necessary to use cable products that serve for signal transmission. In this case, twisted pair, fiber optic or coaxial cable is used. This option is rarely used for covert video surveillance, since it is difficult to organize inconspicuous wiring.

Wireless micro cameras are available in two versions. Some devices transmit a signal using Wi-Fi or other technology, while others work offline, recording video files to a memory card that is built into the equipment. Wireless cameras operate on AC, battery or rechargeable battery.

Important! There are wireless cameras that can simultaneously record information on the built-in media and transmit it via Wi-Fi.

Due to the small size of the wireless models of the first option, the signal transmission range is too low. The equipment receiving the signal should be located as close as possible - in the line of sight. Such wireless mini-cameras for covert video surveillance can be connected directly to a laptop or smartphone, through which video surveillance will be carried out.

The connection is made via a Wi-Fi network. The signal goes to the Internet through the router. Using any device that is connected to the network, you can view the content of the video.

There are factors that negatively affect the use of wireless Wi-Fi cameras. Installing the antenna unmasks the covert surveillance device. When placed in a building structure, the data transfer rate is significantly reduced. Wireless cameras consume more power than standalone cameras. Therefore, in some cases there is a need to connect the device to the mains.

Standalone mini cameras are equipped with a memory card slot. The device is powered by a built-in lithium-ion battery. The camera, depending on the shooting mode, can work from 2 to 30 hours. Such a device should be periodically checked to ensure that the card is full with information and the battery is discharged. Such a camera is not suitable for long-term use without monitoring.

Important! If the memory card is full, it will erase the earlier information, recording the new one.

Unusual device options and spy miniature camcorders

Small cameras for covert video surveillance are presented in a wide variety of species. However, there are unique device models that deserve special attention.

Features of installing a hidden camera at home

Before installing a hidden camera, you should decide on the installation option, which can be stationary or temporary. Both methods have a different approach to fastening, however, the devices must be safely hidden from prying eyes.

The choice of the installation site for covert video surveillance is primarily determined by a good overview. Indoors, the device is best placed in a corner for maximum coverage of the room. The best option is the position of the camera, which provides a vertical angle of 65-75 degrees between the imaginary line of sight and the wall. The more spacious the room, the higher this value.

Most models of portable cameras are not equipped with mounts, so mounting elements will need to be purchased separately (depending on conditions). The best solution is to buy a special detachable platform that adjusts the camera's angle of view. The device can be easily mounted in a drywall wall, fixed on the Armstrong ceiling or disguised as an interior item.

If the device is wired, it is better to install it in the upper part of a bookcase or wardrobe, and hide the wires behind furniture. You can attach the camera to a decorative element, and mask the cable products.
