Hello all,

I am trying to setup a surveillance system for my parents, using some parts from their previous system. I have the card for video input that I can't figure out what it is. This makes it difficult to reference the hardware list that you guys have posted.

here are some pictures of it

I'm not experienced with analogue stuff, but that looks like a four channel Bt878 card, which your distro appears to have correctly identified.

Have you tried simply plugging in a camera and trying to view /dev/video0 through /dev/video3 with video software? I think there's a fair chance it'll just work.

Thanks, you are correct it was a bt878 card and i was able to get it to work. A peculiar thing happened though while i was testing it out. It seems that video0, video1, video2 have all disappeared from /dev. The only thing I changed before this happened was the permissions to the Events folder. Is there any way to get /dev/video0, /dev/video1, etc. back?

it shouldent be effected by that do this.

ls /dev | grep video

to see if devices exists if they do then most likely zm can not write to the event folders check logs.

Also to reload the bttv driver

modprobe bttv

and you can see what happens after loading drivers by this comand
tail -f /var/log/messages

Probably your distribution is blocking it because its an unknown card.

Check in /etc/modprobe.d/ directory and see if there is any file called blacklists. This is what openSUSE does.

If you do modprobe bttv there will be a very long delay but it will load fine... hopefully.
