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. -Moses At 01:41 PM 2/16/01 +1100, you wrote: > G'Day All, Being new to linux and very new to video, I would like to ask for >your recommendations.
