AXIS 243Q Blade - Video & Image 21
Advanced - MJPEG settings
Sometimes the image size may be large due to low light or complex scenery. Adjusting the Maximum frame size is a good way of controlling the bandwidth and storage used by the MJPEG video stream in these situations. Defining the frame size as Unlimited will provide consistently good image quality at the expense of increased bandwidth and storage usage during low light. Limiting the frame size helps optimize bandwidth and storage usage, but gives poor image quality. To prevent increased bandwidth and storage usage, the maximum frame size should be set to an optimal amount.

•Configurable areas as privacy masks - up to three black areas are used to conceal parts of the video image.
The difference between an overlay and a privacy mask is that a privacy mask cannot be bypassed by HTTP API, whereas an overlay can.
