I'm very new to CCTV cameras, my company just purchased about 450 older (unsupported) Siqura model cameras. I'm trying to test them out, and the first one I started with is the MD10A, I was told that all I would need to do is connect the camera to the DVR (via BNC cable) and that would transfer video and also supply power to the camera. I was under the impression that a BNC cable would just carry video and not power. If I do indeed need power for this camera, is there anybody that could help me out with letting me know which power supply would be best for this camera. I've tried the manufactor's website, however they no longer support these older models. I would greatly appreciate any help with these cameras.
