Know before you buy
A ground loop isolator prevents electrical interference that often manifests as rolling bars, static, or 'hum' in your video feed. It works by breaking the ground loop path between your camera and the recording device, resulting in a cleaner, more stable image.
No, this device is bus-powered. It draws the minimal power it needs directly from the video signal line, so you don't need to worry about extra cables or power outlets.
Yes, it is designed for standard BNC connections. It features a BNC male connector on one end and a BNC female connector on the other, allowing it to easily patch into your current coaxial cable run.
For the best results, install the isolator as close to the recording device (DVR or monitor) as possible. This ensures the signal is protected from interference throughout the length of the cable run.
This isolator is designed for standard CCTV video signals. While it effectively cleans up interference, you should verify that your specific camera resolution and signal type are compatible with the device's technical specifications.
