In fact, the underwear camera is an ultraportable camcorder - that is, a combination of a sub miniature television camera with an equally small digital video recorder, designed for continuous video shooting while wearing the device on top. Should wears devices that are worn on the head (on a helmet, headgear, or headband) as body cameras? The question is still open, because scientific classifications in our time barely keep pace with the commodity. At least, helmet-mounted cameras supplied by firefighters are considered by marketers to be a separate market sector. At No Fluff Tech you will different types of camera based on your needs.
From the point of view of sectoral affiliation, wearable cameras are located at the junction of classic video surveillance and with respect to its new modification - managing collection and storage of video evidence. In the judicial systems of different countries, the status of video recordings as evidence may vary significantly, but there are also general requirements for files recorded by wearable cameras. The main group of requirements comes down to guarantees of non-interference in materials in terms of their integrity and content. In other words, the hardware of the devices should exclude the possibility of deleting or editing video content.
Camera manufacturers are constantly improving their products, and at the moment the actual standard of resolution is Full HD. The optics used in most cases comes down to wide-angle; A number of camera models implemented built-in IR illumination. An important function of body cameras is pre-alarm recording, usually tuned to a 30-second cycle. This means that when you press the control button on the built-in storage device, the video recording starts, starting 30 seconds before the moment of pressing. Recording on cameras can also be activated by other events - for example, in the presence of a built-in acceleration sensor, it is possible to start recording if the user starts to run or falls to the ground. Reported and more exotic sensors - for example, fixing the seizure of personal weapons from the holster.
It is quite natural that the body camera, especially used for security purposes, must be weather resistant and withstand certain shock loads. Given the relatively small weight of the devices (usually from 50 to 150 grams), to ensure the corresponding characteristics of security is not a particular problem. As for the load on the batteries, everything is somewhat more complicated. When cameras are used by security guards or police officers, it is assumed that the camera's operating time from the built-in power source corresponds to the duration of the patrol shift. However, not all models are able to provide this, and the manufacturer in the general case can only indicate the average operating time at normal load. Increased load on the on-board processor in low light conditions, the inclusion of IR illumination, low ambient temperature and intensive use of radio communications (4G, Wi-Fi) can lead to a significant reduction in the effective time of the cameras. And this is fraught with the loss of information of value: at the right time the camera can be a useless toy.
The market boom of camera worn for police is currently in full swing. But marketers prefer to ignore the use of cameras outside the power sector, since these practices are literally before our very eyes. Here, perhaps, there is a desire to avoid confusion associated with the growing interest of the mass consumer in home appliances that functionally intersect with wearable cameras, such as GoPro. Nevertheless, the specific requirements for professional cameras have already been settled, and it is not only law enforcement and security structures that acquire this equipment.
Building up the technical characteristics and functionality of wearable cameras is quite predictable, the growth of this sector of the market is determined not so much by the intensity of penetration into the niches already found, as by the search for new areas and conditions for the use of these devices.
Today, ultraportable personal video recorders are successfully used by parking inspectors, museum supervisors, technical inspectors, passenger vehicle crews, medical staff, and school teachers.
Experts are inclined to believe that confirmation of the effectiveness of investments in wearable cameras is only a matter of time, and the list of professional applications of ultra-portable camcorders will expand from year to year.
Judging by the latest trends in the use of body cameras, they have found their place at the intersection of professional and “amateur” use. Recently, in a number of countries, there has been a volunteer civil patrol initiative. Volunteers, walking on urban spaces, continuously shoot, and when fixing offenses transfer records to the police.
As the capabilities of cameras increase and they become cheaper, it may be possible to implement the integration of video patrols into a single collective surveillance system, where the coordinates of the cameras and their orientation are tracked in real time. The newest cameras already have all the necessary technical prerequisites for this - in particular, GPS and Wi-Fi. It is only a civil initiative, as well as its organizational and infrastructure support.
Among the factors hindering the introduction into the practice of wearable cameras and decisions based on them, the most significant are legislative restrictions. In many countries, human rights defenders are trying to offer reasonable resistance to the use of ultra-portable video recorders by the police, declaring this to be a “disproportionate measure”. In addition, the computational power of on-board camera processors already allows the use of face recognition algorithms in real time - and linking a person to a specific time and place in most countries is treated as personal data and is subject to relevant legislation. True, American human rights activists have, in fact, lost the battle with road cameras that automatically recognize license plates. It is possible that the wave of resistance of the body cameras will similarly subside.
