Monoprice 1 Channel Passive Cctv Balun - Video/power Over Cat5
This pair of single channel passive video baluns will carry video and power over Cat5 Ethernet cable, giving you the ability to utilize straight network cables to connect your cameras. Simply connect the BNC ends to your camera and your recording device or display, connect the DC ends to a Power Supply and the Camera, then connect your network cable through the RJ45 jacks. Depending on camera power draw, power output, cable size, and environment, results will vary. Average conditions allow transmission up to 1,000 ft. On longer runs video quality might be slightly reduced.
The DC jacks have a 5.5mm barrel size and 2.1mm pin size.
