#Operational video surveillance
Operational video surveillance in vehicles.
Unfortunately, modern reality is such that we have to pay more and more attention to security measures, constantly upgrading and improving them.
Constant threats of terrorist acts aimed at destroying as many civilians as possible do not allow us to relax and force us to develop new technologies and look for new solutions.
This is especially relevant for all types of transport, from passenger transport with a large crowd of people to means of transporting valuable cargo, cash-in-transit vehicles.
Working in the security field for over 18 years, our company has used many different means of protecting objects in its activities, however, today, the best means is the use of a video surveillance system.
But video surveillance does not always satisfy the consumer, since many of them do not provide a «clear picture», so in our work we use the new SerVision technology — DVR (hereinafter referred to as recorders) of a new generation, allowing you to broadcast video signals using wireless technologies («over the air») in real time with the clarity of a TV signal.
Moreover, this technology allows not only to observe what is happening outside and inside the vehicle, unlike the previous ones, which can only track a moving object on a map using a GPS signal, but also, using a regular computer equipped with a special program, to control the vehicle: stop the fuel supply, stop it or lock the doors until the arrival of law enforcement agencies.
A unique algorithm compresses the video signal to a level that allows it to be broadcast via GPRS-EDGE cellular networks and WiMAX wireless networks.
As a result, traffic will not limit the transmission of video images in real time.
A channel with a capacity of 9.6 kbps is sufficient to transmit one frame.
This technology has opened up previously unused opportunities for real-time video surveillance in open areas, in moving objects, and in rooms not equipped with a cable network.
A stable cellular network or wireless Internet connection is sufficient to transmit video images.
The infrastructure requirements for this technology are minimal — one or more video cameras are installed in each vehicle.
A portable shock- and vibration-resistant recorder to which the cameras are connected.
There is no need for «buffering» or processing of data on any intermediate server. The vehicle is also equipped with a cellular modem.
Video signal reception is carried out on terminals, PCs, laptops, cell phones.
Viewing images and streaming video from the object at any time and at any point in REAL TIME mode not only on stationary monitors, but also on peripheral communication devices such as: cell phones, GPS navigators, stationary and portable PCs.
In addition to viewing video images, it is possible to broadcast TV channels to the same peripheral communication devices and also in real time.
At the same time, it is possible to transmit images and sound also via high-speed channels (ADSL, CDMA, UMTS, IP, WiFi).
The recorders are fully equipped with the functions of «alarm» inputs and simultaneous recording and broadcasting. To optimize the response of security services, a special program has been developed, which is a hybrid of a GPS map and a video map of the streets.
With the help of high-resolution cameras, it is possible to clearly distinguish the faces of passengers, banknotes, receipts, etc.
In all application options, video can be broadcast in real time with simultaneous recording at minimal cost.
The standards of this equipment are, in fact, modules that our company's development specialists adapt to the customer's technical requirements, thereby offering in each specific case not only an optimal, but also a unique technical solution for video surveillance.
With the equipping of Russian regions with WiMAX networks, it has become possible to conduct video surveillance in real time from train cars and electric trains, if there is wireless Internet or GPRS networks along their route.
Broadcasting is carried out via GPRS-EDGE cellular networks and WiMAX wireless networks.
Passenger trains, like freight trains, can be equipped with video surveillance systems.
The only condition for broadcasting video in real time is the availability of a cellular network signal or wireless Internet along the train route.
Technically, the configuration can be simplified to equipping the cars with any analog video cameras.
Each of which is connected to a mini-router, which simultaneously records and broadcasts video.
If necessary, each carriage can be equipped with more powerful digital video recorders that perform the same functions.
Video reception, recording and processing can be carried out on small servers installed at stations, computers, and cell phones.

Naturally, this technology is used not only in vehicles, but also in other areas of life.
It is optimal for objects located in hard-to-reach or inaccessible places. standard video surveillance in places where it is impossible or unprofitable to install expensive cable communications: luxury cottages, municipal, industrial, construction sites, pipelines, power lines.
