2. The audio subsystem
3. The analytics subsystem
4. The PTZ subsystem
5. The event registration subsystem
6. The notification subsystem
7. The relay subsystem
These subsystems can interact in either a single-server or multi-server (distributed) system.
This section provides information on the software’s basic functions.
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 EyStream 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 EyStream'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:
a. Current time
b. Name of video camera
c. Audio volume
d. Indicator of recording of video image from a camera
e. Video stream settings (if configured accordingly; see the section Configuring Display
of Video Statistics )
3. Video image processing
a. Digital zooming
b. Contrast adjustment
c. Deinterlacing
d. 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, Snapsh
ot, etc.
