Digital Video Surveillance System
IP video surveillance is a video surveillance system that uses digital surveillance cameras, digital communication channels and digital equipment for recording audio and video information. A modern IP video surveillance system may include IP cameras of various types, computer or specialized systems for storing and identifying video streams. To transfer the information received by the IP video camera to a digital server or registrar, both specialized digital communication channels and the global Internet using various video information transmission technologies can be used. It is the use of the global network for information transmission that explains the growing popularity of digital IP video surveillance.
The emergence of fully digital IP surveillance was facilitated by the emergence of such a device as an IP camera. If before that video was transmitted in analog form, and the surveillance camera was just a source of video signal, then after the advent of such IP surveillance cameras, the situation has changed radically. Firstly, the IP video camera already produces a digital signal that can be transmitted in any convenient way. Sometimes, according to tradition, video from IP cameras is transmitted via specially laid communication channels, but in most cases, the Internet or local digital networks can be used for this purpose, which practically removes the limitation on the image transmission distance.
Features of Digital Video Surveillance
Another significant difference between digital IP video surveillance and analog is the fact that the IP camera itself, in fact, is a stand-alone video surveillance system. Any IP camera in a digital IP surveillance system has its own address, knowing which, you can connect to it from anywhere in the world. Also, digital cameras have their own interface and software, which is responsible not only for the settings of the IP camera, but also allows it to be controlled, as well as to provide activity tracking in certain areas in the field of view of the surveillance camera. For this reason, the capabilities of IP video surveillance are largely determined by the design and functionality of the IP cameras that are part of the IP surveillance system.
Prospects for the Development of Digital Video Surveillance Systems
Digital IP video surveillance systems have great development prospects, as they are being improved in parallel with other digital equipment and modern IP technologies for data and image transmission. Already now, IP video surveillance is beginning to replace outdated analog or combined video surveillance systems everywhere, therefore, thinking about the future, it is worth paying attention to the use of fully digital IP video surveillance.
