I have a camera recently removed from a job I was working at replacing with new ones,and these cameras only have an "svideo" connection. My question is this, is there no power needed to view this camera? Thanks for your time, I just was curious as I may wish to reuse this camera.
If it's a real s-video connection and not just something that looks like one, there is no way it will run with only that. It may have another power connection, or run on batteries. s-video does not supply any power.
Posting the camera brand and model may help, or just do a web search on your own.
