How to use digital optical transceiver to establish security video network

With the development of urbanization in China and the continuous occurrence of unexpected events, the public security and emergency systems of cities are increasingly focused on by governments at all levels. One of the most important parts is building a security video surveillance network. This article introduces how to use digital optical transceivers to establish security video surveillance networks for small and medium-sized cities and towns.

Although there are many different video transmission plans available today, in building security video surveillance networks for small cities and towns, we recommend using digital optical transceivers to create so this foundation.

Currently, line rental services from radio, film and television, telecommunications, netcom networks, etc. available, but E1 leased lines and VLAN special services are expensive. Conventional broadband lines primarily serve digital services, causing problems with video quality of service (QoS), clarity, and other issues.

Security video surveillance networks often have a star structure, requiring high bandwidth at the center.

Renting broadband lines requires a lot of equipment and high costs, and complex system maintenance. Renting broadband lines, users need to configure various types of optical transceivers, E1 multiplexers, L2/L3 switches, and video encoding. Due to the high demands on equipment and expensive equipment costs, it is necessary to pay high salaries to system maintenance staff.

On the contrary, the cost of pulling fiber optic cables for small and medium-sized cities and towns is not high, and fiber optic cable prices are decreasing rapidly. With digital optical transceivers, video transmission over fiber optic cable can reach the level of radio television, superior to MPEG2, MPEG4 and JPEG.

On fiber optic cable with digital optical transceiver video transmission scheme, the video transmission devices used are optical transceivers. The digital optical transceiver does not require any installation or adjustment. No need for professional background to install.

No need to pay rent, can use long term.

Using single video channel/backhaul of a pair of digital optical transceivers will transmit the video signal of the surveillance camera to the monitoring center, using a video distributor can split the video signal into two lines , one line into the video matrix, one line into the hard drive video recorder.

Connect to the video display matrix, through the video matrix control keyboard, can decentralize video control.

Currently, there are many types of optical video transceivers on the market for contractors to choose from, but the following factors need to be considered:

The matrices of several towns and villages can be connected to video relay, first relay the video through multi-channel optical video transceiver, in the picture below, the command center screen 110 can display videos of A, B, C can simultaneously display the four most prominent images of town A.
