If JPEG mode is selected, the Network Camera continuously sends JPEG images to the clients, producing dynamic effects similar to movies. Every single JPEG image transmitted guarantees the same image quality, which in turn comes at the expense of variable bandwidth usage. And because the media contents are a combination of JPEG images, no audio data is transmitted to the clients.
■Frame size
Select the video size. Note that a larger frame size takes up more bandwidth. The frame sizes are selectable in the following resolutions: 176 x 144, 320 x 240 and 640 x 480.
■Maximum frame rate
This limits the maximal refresh frame rate per second. Set the frame rate higher for a smoother video quality.
