best picture quality security camera image
skyking196
Every day on the news, there's at least one story of a small store robbery, or a car that crashes through a window, etc. They show the actual footage from the security cameras and the quality is mostly awful... choppy, blurry, sometimes in black and white. You would think these days they would have high resolution video, especially if they wanted a good look at a thief or attacker. I don't know much about security cameras, is the technology just not there yet?
Answer
The reason so many surveillance systems appear to be low quality can be attributed to the need for a compromise between image quality and storage length, and cost. As you increase the quality of the image, the price of the cameras used to obtain the picture goes up, as well as how much storage space is needed to keep the same time length of data. For example, a security camera system recording at a lower 360 x 240 (CIF) resolution can keep its data approximately 3 times longer than the same security camera system recording at 720 x 480 (D1) resolution. If your surveillance system recording at CIF resolution can keep 45 days worth of video data, D1 would last approximately 15 days before it starts to overwrite.
The technology is absolutely available for higher quality images, but in most scenarios is limited by cost.

what are the best security cameras to use for night recording? IR or low lux?

I am putting in a surveillance system because our house is getting constantly tp'ed and want to figure out who is doing it. Cost isn't really a problem but within reason, I obviously am not going to install FLIRs around my house but something in the $100-200 range per camera. Also, does anyone have any good DVRs in mind? I want the best picture quality and internet viewing.
Thanks!
