Elevator video monitoring cable manufacturers tell you that monitoring cables are a general term for various wires that transmit electrical or optical signals. Elevator video monitoring cable manufacturers tell you that the monitoring cable is usually a kind of covered wire, which is composed of multiple copper wires and steel wires twisted into a conductive core, which is wrapped with insulating material, which is tensile and wear-resistant, easy to retract and use repeatedly. There are video lines, radio frequency lines, shielded and unshielded, signal lines, control lines, etc., various models.

Video cable laying precautions:
1. The manufacturer of Elevator video monitoring cable tells you that if the distance from the camera to the monitoring host (image processor, matrix control host or digital video recorder) is less than 200 meters, RG59 video cable can be used. If it is more than 200 meters, SWY-75-5 should be used video cable to ensure the quality of the monitoring image.
2. The manufacturer of Elevator video monitoring cable tells you that for the camera installed in the elevator, the wiring in the elevator shaft should use star iron groove and grounding treatment to reduce the interference to the video signal when the elevator motor starts.
3. If the camera is installed outdoors (such as the gate of the compound or the parking lot, etc.), the line needs to be routed outdoors or through an overhead steel cable. The Elevator video monitoring cable manufacturer tells you to install a video arrester if conditions permit (because The installation of lightning protection equipment will increase the total cost of the project), that is, install a video lightning arrester on the camera side and the monitoring host side respectively, and each video arrester must be grounded (outdoor cameras need to be grounded separately, and the monitoring room The video arrester can be grounded uniformly) to prevent damage to the equipment caused by induction lightning.
