Peter,
If you think about it, most cards have 2 inputs you can use (if you dont
need a constant movie stream), composite and the tuner.
Buy yourself some regular security cameras, I have purchased many hrc-400s
from www.spycameras.com, only $80 and 400+ lines!
Run one to the composite input and one to the tv tuner using an rf
modulator, the ones used for video games and such (~$20).
Two WinTv Go (bt484) cards should run you no more then $100. I've also
found you can get a better picture with longer runs if you convert the rca
plug into coax at the camera. So..
2 WinTv Go cards $100
2 RF modulators $40
4 HRC-400 cams $250
Total $390 not bad for 4 cameras!
If you are really using this for security either lock up the box in a safe
that is bolted to the house, or do like I do and scp (or ftp) them to a
remote location. The first thing a crook is gonna take is your computer,
and all the nice pictures that you took of him taking it!
BTW, I take a jpeg snapshop with the streamer app included with xawtv (HEY!
no gray scale jpeg capability in the new one!!!) every 2 seconds, which
adds up to almost 2.5 gigs per day per camera. Convert all those to mpegs
later with mpeg_encode, and you get a 5 meg file per hour of all the
pictures or a 10 meg all day mpeg using one pic from each minute.
Good luck.
