LTR-2 is designed for applications in CCTV systems in which video signal is transmitted over a twisted pair cable. It can be also utilized for video signal transmission (e.g. from 2 CCTV cameras) via an existing computer network (2 idle pairs may be employed). The device enhances systems with video transformers TR4/4 (M1667) and TR-1 (M1665). LTR-2 device does not require any additional power supply.
