Hello,
Im working on configuring this zoneminder system on Ubuntu Server and it appears as I have zoneminder installed and I can log into it. However I havent added any cameras as of yet. Its a 16 Channel card and I purchased it from Blue Cherry, however in terminal i only have 4 /dev/video devices. I have video0 video1 video2 video3.
Shouldnt there be a total of 16 of these if im not mistaken? Or is there more I have to do to get all 16 of them to show?
Thanks

Maybe you have 4 channel on every device, 4 x 4 = 16 channels.
Did you tried it?

Yeah I think your correct, however now im noticing a different error, maybe because out of all the ports i only have one camera connected currently?

No it's not because you have only one camera connected, I think this is because of the aspect ratio (WxH). Review you monitor configuration (try to probe the camera) and try again.
Regards.

Ok, now i got it working for the most part, however i can only get 8 of the 16 channels to work, I found the first 8 because they were all channels 0 and 1, however when getting to camera numbers 9-16 they are not showing up under channels 2 or 3. Ive tried a few other channels but still cannot find them.
