Here are some possibilities I've considered:
- V4L cards. This looks good, but I don't know if there's a V4L card that can terminate 6 cameras. I've used V4L to capture analog cable with MythTV, so I have some hardware, but not 6 channels worth.
- External capture device that ZM can interface to over Ethernet. I've seen some reference to commercial products that can convert analog cameras to IP, which ZM could then capture, but these seem expensive. Are there cheaper ones?
- Replacing the cameras with IP cameras, by re-purposing the 2 video and 2 power lines to create a 4-wire POE connection to more modern IP cameras. This would require more work, and I'm not 100% sure the cables would be able to provide a reliable Ethernet connection. However, if the QM-7007B cameras are not worth keeping, and modern POE IP cameras were cheap enough, I would consider this option as well.
- Something I missed? I'm sure there are other possibilities that I haven't thought of.
