Compression rate settings

...

1. Go to the Hardware tab in the System settings dialog box (1).
2. Select the Camera object, created before, corresponding to the camera to be adjusted, in the objects tree of the Hardware tab (2). The settings panel for the selected object is displayed on the right of the Hardware tab.
3. Go to the Basic settings tab on the settings panel of the Camera object (3).
   

4. If it is necessary to improve the video quality, move the Quality slider to the Max (4).
   If it is necessary to reduce the size of video stream from the camera, move the Quality slider to the Min.

Key frame rate settings

Axxon PSIM™ software uses Motion Wavelet algorithm for video processing and compression. Processed by this algorithm, the video is the sequence of key - − and delta frames. A key frame is a full frame of an image. A delta frame (differential frame) is an image containing only pixel blocks which differ from the previous key frame.

Axxon PSIM™ software uses Motion Wavelet algorithm for video processing and compression. Processed by this algorithm, the video is the sequence of key - and −and delta frames. A key frame is a full frame of an image. A delta frame (differential frame) is an image containing only pixel blocks which differ from the previous key frame. To compare the pixel blocks of a key frame to those of the frame next to the key frame, the average brightness of blocks is compared. If the difference in brightness exceeds a preset value, the block is considered to have fixed motion, and it becomes a part of a delta frame. Otherwise, the block is considered to have no motion, and it is not included into the delta frame.
