Realtime Video Balun LLT-401R Transceiver Video / Audio / PTZ Signal 4 CH

The LLT-401R is a 4-channel active video balun receiver used in CCTV security systems, allowing multiple video signals to be transmitted over a single unshielded twisted pair (UTP) cable (like Ethernet) to reduce wiring, featuring gain/brightness adjustments for image quality. It works in conjunction with a transmitter (LLT-401T) to send video from cameras back to a DVR, ensuring clearer images over longer distances.
