With the enhancement of safety/security awareness, all walks of life now have their own remote monitoring systems. On the one hand, anti-theft awareness is increased, and on the other hand, safety/security management can be carried out. Remote monitoring software is also welcomed by many enterprises.
What is the working principle of remote monitoring?
Will come from each video camera The video signal is input into the video capture terminal, and then the video capture terminal converts the video signal into a digital image of 25 frames/second through the image compression algorithm, and forwards the compressed audio and video data stream to the video monitoring center through the network; Then, the monitoring computer in the video monitoring center decompresses the image and sound data received from the front end, and conducts real-time monitoring through the computer display screen and sound card.
When an alarm occurs, the alarm decoder will link the alarm output device, input the alarm signal to the video terminal through the alarm decoder, and transmit it to the monitoring center, the video of the monitoring center The server After receiving the alarm signal, sound signal will be sent immediately, alarm events will be recorded, hard disk recording and other alarm operations will be performed.
The camera control, deployment and other control signals are transmitted in the downlink. The monitoring host of the monitoring center sends out various control signals. After receiving the control signal, the video acquisition terminal passes through the pan tilt lens controller Or directly control the camera, or complete the deployment operation.
The system adopts the hardware compression software decompression technology, and the remote video monitoring function can be realized by adding the corresponding software on the computer terminal of the relevant department or through the Web function of the IE browser provided by Windows, which can be set as a video monitoring workstation.
TCP/IP and Multicast technologies are used for network communication, which makes full use of the network transmission performance and network bandwidth to avoid network congestion.
