best security camera resolution image
Striker
I want to have an always-on motion activated security camera that supports wifi or even wired ethernet that can upload to a web server or ftp. I don't want to leave my computer on all the time.
Answer
Yes. They are called IP or Network cameras.

Here are a few. I actually work for this company. Funny I ran across your post while answering miscellaneous questions. If you ordered from us, your camera would likely pass through my hands.
Another guy mentioned Netbotz. They are proprietary. If you want temperature readings from them, you need to buy their whole system. If you're going to do that, they are not the best. Pelco dominates the high end of this market, but they cost a fortune. If you want what you asked for which is just a camera by itself with a lot of uploading options and motion detection, I suggest a network camera by Toshiba, Canon, Axis, or Vivotek. If you want insane resolution as well, look at IQ Eye (but costly).

Why is all security camera footage so terrible?

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.
