Many users have questions: how to set up the video optical transceiver and how to control the PTZ? One fiber core can transmit several channels of video. Can we use two 4-channel optical transceivers at the camera end and one 8-channel optical transceiver for the monitoring center?

The video optical transceiver has a transmitter and a receiver. The transmitter is placed next to the camera, and the receiver is placed in the computer room. The optical fiber cable is used in the middle. In addition to transmitting video, the optical transceiver can also transmit control signals, that is, 485 signals. At the same time, it can transmit audio. , Ethernet, switch signal and other signals, all the signals can be transmitted through a set of terminal equipment and one core optical cable. Of course, the more signals transmitted, the lower the price. Generally, the number of optical terminals is selected according to the situation on site. It is the most common optical transceiver to transmit video and data with multiplexed signals. The data port can generally connect 1-32 PTZs. The keyboard sends a signal to the optical transceiver, and the optical transceiver sends the signal to the dome camera. It is very convenient to control the PTZ. .

Generally, a fiber optic cable can transmit 1-128 channels of images. Two 4-way optical transceivers are used next to the camera. Under normal circumstances, the receiver must also be two 4-way optical transceivers. This is a point-to-point optical transceiver. Unless you use a cascaded optical transceiver, connect two 4-way transmitters with a single-core optical cable, and then pull the optical fiber to the cascaded receiving optical transceiver in the computer room to achieve the situation you said, but the price of this optical transceiver is point-to-point. Optical transceivers are more expensive, less used in general monitoring projects, high price, more restrictive, less multiplexed signals and other reasons, which determine that they are rarely used in general monitoring projects.
