Video subsystem

The video subsystem encompasses all the tools that provide for the acquisition of video data, its processing, and its storage on media.

Video data comes in from IP devices connected over TCP/IP or from analog video cameras connected through video capture cards.

Video data in the Axxon Next software package is processed automatically by the analytics subsystem or manually by an operator. Depending on the task, the results of the video data processing are transferred to and utilized by other subsystems of the software package, including the event registration subsystem, the notification subsystem, and others.

The following system objects enable the functions of the video subsystem:

1. Camera
2. IP server

The functions of the video subsystem take place through the following user interfaces:

1. Video surveillance monitor
2. Viewing tile
3. Control elements accessible to the user in the Layouts tab

Thanks to Axxon Next's video subsystem, the user can utilize the following functions:

1. Viewing video images in a supported resolution from a video camera while simultaneously listening to the audio from a microphone linked to that camera (if it is connected to an IP server) or connected to it physically
2. Displaying information in a viewing tile:
   
   1. Current time
   2. Name of video camera
   3. Audio volume
   4. Indicator of recording of video image from a camera
   5. Video stream settings (if configured accordingly; see the section Configuring Display of Video Statistics)
3. Video image processing
   
   1. Digital zooming
   2. Contrast adjustment
   3. Deinterlacing
   4.  Sharpness adjustment
      
      
4. Modifying layouts, including changing the sizes of viewing tiles
5. Displaying a magnified video image from a selected video camera (viewing tile)
6. Displaying a snapshot initiated by an operator, without interrupting video recording
7. Color coding a viewing tile (video camera) to indicate its status: Alarm, No alarm, Snapshot, etc.
8. Video recording can be performed:
   
   1. continuously;
   2. video recording initiated by a detection tool or by an operator, with a pre-alarm recording option;
   3. scheduled video recording.
9. Recording to archive (video and audio streams are written to one file)
10. Storage and export of single frames and video sequences

11. Playback of video image recorded to the archive from one or more video cameras (in the latter case, playback will be synchronous) with simultaneous playback of sound recorded together with the video

    Note

    In the case of synchronous playback of video from several video cameras, the sound is played back only from the microphone of the active video camera

12. Working with alarms registered by one or more video cameras:
    
    1. Navigating between archive recordings of alarms
    2. Viewing brief information on an alarm and its recording in the archive
    3. Filtering alarms
13. Using any Client to view video footage from all Servers over TCP/IP
