2. Priority display of videos from active or alarm cameras.
3. Change the number and relative position (layout) of surveillance windows.

5. Display of service information in the surveillance window: current time and date, camera number and name.
6. Display of an alarm notification window.
7. Video scaling.
8. Scrolling through surveillance windows in automatic and manual modes.
9. Video recording in the following modes:
