Ok I am looking to buy some surviellance cameras and I have questions, advise would be great.
1. What does the "lines" means? 480 lines ?? 360 Lines..what does that means. Does that make my video clearer, smoother and better quality if I have more lines in my camera ?
2. Capture cards for surviellance has different FPS. What does it means? There's a card that has four channel w/ 30FPS. So I guess 30FPS/4camera=7.5FPS each ?? So does that 7.5 FPS good ?? Is my video plays smoothly ?? and good quality in the video file?
3. With Motion Sensor Detection, does that comes as an option on the software with the capture card. Or an option built in with the camera?
Please help...Thank you,

There is no one answer to your question. There are many variables involved. For example, a human can identify a picture flashed in front of them for only a 1/200th of a second (or 200 FPS), but movies are shown at only 24FPS but are not jerky.
As for motion sensors, they could be either hardware or software. Hardware would probably be more expensive though."A beginning is the time for taking the most delicate care that the balances are correct."

They sell anything from individual cameras to "Estate" security kits. They have a VCR Commander that turns on the VCR to record when motion is detected, more remote control stuff than you can shake a stick, mostly reasonable.
I have a bunch of the stuff myself.. The cameras are not DVD quality, but you would recognize an approaching person, if you knew him, of course.
They also have low light cameras. -
Shocker,
They do do that, don't they?
I haven't bought anything for over a year, my daily e-mail"sale" brochures finally stopped.
Still, it is reasonable, and works.

If the "click through" rate went too low, probably wasn't cost effective..
Kinda happy about that. Now if only some others would die.....
