How large are the images in Kbytes?
The size of the image depends on the resolution and the compression scheme used. An image of (352 x 288 or 352×240) that is compressed using MJPEG is only about 4-10 Kbytes. Higher resolution cameras such as the IQ301, with resolution of 1200 x 1024, create file sizes as large as 80K bytes per frame. Since MPEG4 improves compression by transferring only the difference between frames, we don’t use frame size with MPEG4 compression. Instead we estimate an average data rate based on the resolution, frame rate and expected activity the camera will see. In general you can expect about 4 times improvement in compression using MPEG4.

A: The bandwidth depends on the number of cameras, the resolution of the cameras, the compression scheme used, and the frame rate of the cameras.
