Power & Video Balun: Gold Plated BNC provides better transmission quality and long-distance HD transmission. Super Extensive Applications: Supports all video devices such as cameras, monitors, DVR cards, and recorders. Compatible with all digital CVI, TVI, and AHD cameras. Video Transmission via UTP CAT5: LED indicates working status (green light) or fault (yellow light) via RJ45. Easy to Install: Includes a detailed installation guide for simple and convenient setup. This Video Transceiver with Power is a passive (non-amplified) device that allows transmission of real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire. Supports baseband (composite) signals of any type. Enables transmission of CCTV video and low-voltage power over UTP cable. Power and video are transmitted via UTP and RJ45 connections. High interference rejection and low emissions allow video signals to coexist in the same cable bundle as telephone, datacom, or low-voltage power circuits. Enables use of shared or existing cable infrastructure. Compatible with HD-CVI, HD-TVI, and HD-AHD. Video transmission up to 450m for 720P CVI cameras. Video transmission up to 250m for 1080P CVI cameras. Video transmission up to 250m for 720P/1080P TVI cameras. Video transmission up to 320m for 720P AHD cameras.
