The Monoprice 1 Channel Passive CCTV BALUN is designed to transmit video, audio, and power signals over a single Cat5 network cable. This innovative solution simplifies the installation of CCTV systems by allowing users to utilize standard network cables instead of traditional coaxial cables. The balun features BNC connectors for video and RCA connectors for audio, ensuring compatibility with most CCTV cameras and recording devices. With a transmission range of up to 1, 000 feet under average conditions, this balun is perfect for both residential and commercial surveillance applications. Simply connect the BNC ends to your camera and recording device, attach the DC ends to a power supply and camera, and use the RJ45 jacks for the network cable. Please note that the performance may vary based on camera power draw, cable size, and environmental factors.
