Specification Description: This video transceiver with power supply is a passive (unpowered) device that allows real-time black and white or color video transmission over unshielded twisted pair (UTP) cable. Power and video are transmitted via UTP and RJ45 connections. Its unparalleled interference rejection and low emission allow video signals to coexist in the same cable bundle as telephone, data communication, or low-voltage circuits. Features: Compatible with HD-CVI, HD-TVI, HD-AHD, NTSC, PAL, and SECAM video formats. 60 dB crosstalk and noise immunity. Compact size and easy installation. Saves 30-50% on cable costs.
