If JPEG mode is selected, the PVC300 PTZ Internet 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.
