I use both (but gradually spending more and more time on my debian desktop, I've used linux for years but server stuff).
You can find some bt87* based boards pretty cheap on ebay (some only have one encoder, though some have 4 encoders).
You mean RCA in. There's some cards on ebay for like store monitoring cameras, multiple cameras. I plan on getting one of those. It shouldn't take up too much memory (plus I'm not going to be using an epia.... I'll be using a Semptron 2800+). The video is in B&W, and its not high resolution (compared to DVD). I want to see what the color CCD looks like. I'll probably end up putting it for trade for a B&W one later if I don't like it.Originally Posted by Genesisfactor
hehe, nitemax has actaully made me want to invest in a TV capture card wit its RCA out. I'm still not sure why you want to record everything at all, since you'll either need to set up an auxilary computig system to do it easily (see SBC) or have it leech valueable proccessor and memory space. but i would do a solid state or microdrive, for shock restance and best writing performance under bumps, and then burn its contents to DVD. maybe i don't get why you want to because i don't like creating, having, and stockpiling DVDs of hours of evidence of my traffic transgressions
Hard drives can now withstand some pretty big shocks (atleast based on the specs of my maxtor).

And people ask me why I'm going with a full sized ATX board
RCA in..sorry.
HDD's can survive shocks with data retention, but for writing, since you have fast spinning moving platters, writing and reading is a differnt story at times. Solid state media has no moving parts, which is why HDD based mp3 players aren't recoomdending for jogging or excercising while flash based players are. The trade off is speed for rugged reliability. I mean, for video, you want speed and data retention, but the last thing you want is to be reading, writing, and then bump, you got a new bad cluster that causes your video playback to freeze because of an "unexpected error".
Also, get B&W. I'm curious to see what color will yeild, but B&W is wonderful enough in my mind. That reminds me...i was supposed to take pics last night before i crashed, wasn't i...

Thought so
If the data doesn't get written, it doesn't just disappear. It gets written somewere else. I think what the engineers did with the new HDs (I've got a maxtor 160gb with NCQ) is make sure that the heads don't hit each other during bumps. Specs. Operational shock for 2ms ing (G): 60... Non-operating Mechanical Shock for 2ms (G): 300. So I'm sure that it will survive. As impacts are not that long. IIRC airbags go off at 3G.
I guess I could go for B&W. If it means cleaner image then yeh. I'm just kind of curious if you know what I mean

Hi guys,
I got my camera today. Is the 2.5mm lens from ebay($15 with shipping) good ? what about 4mm and other lenses? do I need cs mount or c mount ?
thx
CS-Mount screws right in to the camera. C-Mount, if you find one, needs an adapter.
Which 2.5mm lens are you considering?
how about one of these Mark ?
the lenses cost as much as the camera !!

How sure are you that 2.5mm is what you need? (2.5mm will be a wider angle lens.) The first auction doesn't mention f-number, based on the price it is probably pretty bad. The second one is f/2.0 which is not as sensative at night. There's a 4mm f/1.6 that'll do better at night if you're willing to spend a couple of bucks more. The seller "johnjqx" accepts offers, maybe you can make the price a little better on one of the f/1.6 lenses.
OK thx Mark,
I didn't know at all which lens to get. Just saw someone talking about 2.5mm so started looking into it.
cheers
