Re: quad video processor

bbrouwer,

Thank You for your question. You can use this quad video processor.

You need to convert the S-video connections to BNC by using this S-Video to RCA converter.

And this RCA to BNC converter.

Please note that this will only work if the camera connectors truely are S-Video. There have been some proprietary CCTV camera connectors that I have seen in the past that look like s-video but are in fact a proprietary connector that runs both the video and power of the camera.

Please let us know if we can help further.
