The video surveillance subsystem allows video monitoring (event video component viewing) and video recording (event video component recording) by providing:
- multiple video camera images simultaneously displayed on a PC screen (multiple windows displayed on a single monitor and multiple monitors used on a single physical PC screen);
- priority-oriented displaying of active and alarm cameras video stream;
- flexible split screen configuration, including the number of windows on the monitor;
- colour coding of the camera state in the window (Armed, Alarm, Recording);
- image burn-in option in the surveillance window: current time/date, camera ID and name;
- displaying of alarm notification window;
- image scaling;
- automatic or manual windows slide show;
- video recording can be performed:
- if an alarm event is detected;
- by Operator command;
- pre- and post-alarm event recording;
- pre-alarm event recording with post-alarm recording by Operator command.
- single video frames storage and exporting;
- freeze frame selection and viewing, without interrupting the video recording;
- audio- and video-archives management;
- remote access to audiovisual streams from any workstation with both a local and remote archive recording option;
- viewing archive recordings with search and retrieve options on time, event type, camera ID criteria;
- synchro playback of footage recorded by several cameras;
- image processing option (digital zooming, image sharpening and contrast maximization, dynamic outlining of moving objects, removal of image fluttering);
- web interface-based surveillance;
- use of various types of intelligent motion detectors (motion detectors, face detector, lost items detector, focusing detector, video signal stability detector, background change detector, camera tampering, infrared detector);
- use of independent detector zones;
- detector masking.
