An 8 MP CCTV balun is a device used in CCTV (Closed-Circuit Television) systems to convert signals between a coaxial cable and twisted-pair cables (like Cat5e or Cat6) for transmission of high-definition video, typically for cameras with up to 8 megapixels resolution.

Key points about an 8 MP CCTV balun:

1. Signal Conversion: Baluns allow for the transmission of HD video signals (like 4K or 8MP video) over long distances using the more cost-effective twisted pair cables rather than coaxial cables.

2. Compatibility: The 8 MP CCTV balun is designed to work with high-definition cameras, ensuring that the signal integrity is maintained over the twisted-pair cables without significant loss of quality.

3. Distance Support: Depending on the quality of the balun and the cable, they can transmit video over distances of up to 300 meters (or more) for lower resolutions, and a bit shorter distance for higher resolutions like 8 MP, but it's still much more flexible compared to traditional coaxial solutions.

4. Powering CCTV Cameras: Some baluns are also capable of supporting power over Ethernet (PoE), meaning they can transmit both power and video signals over a single twisted pair cable, simplifying installation.
