a watchdog program in FreeBSD?

 Hello. I have a "STMicroelectronic USB Dual-mode Camera" that shipped with 
a Windows watchdog program. When truned on it detects moves, and alarm for 
possible human move. It is useful to guard the house. I've been using it 
for sometime.

Now I wish to use in in FreeBSD. Would it be difficult to find drives and 
watchdog programs for it? I didn't find one in the port collection.
