Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors. It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint, or mesh wireless links. Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores. Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called.
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room, for example when the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing digital video recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion detection and email alerts). More recently, decentralized IP cameras, some equipped with megapixel sensors, support recording directly to network-attached storage devices, or internal flash for completely stand-alone operation. Surveillance of the public using CCTV is particularly common in many areas around the world. In recent years, the use of body worn video cameras has been introduced
CCTV cameras play an important part in road network management. They are installed at sensitive locations on the network to support traffic management, where congestion and traffic queues are frequent and at other locations where there is an increased risk of accidents and traffic incidents.
Teltonika DualCam solution is perfect for capturing videos or pictures of the events that might occur on the road, e.g. crash. Mounted on the vehicle front window, two cameras are used, front and rear, to record videos before and after the events, take photos periodically or by request and send all data to the server. Besides, the innovative solution ensures the safety of passengers as recordings are made of what is happening inside the vehicle.
You can also get the videos or pictures on all scenarios, such as green driving, idling detection, unplug detection, towing detection, or geofence, by sending a request from server. Connected over RS232, trackers FMC125 with dual camera support High Efficiency Video Coding (H265) for a fast video file delivery. For an easy implementation with server, we prepared a universal communication protocol.
