Figure 43 Display properties

Enabled is a standard NiagaraAX property.

Video Display Multistream supports these sub-properties:

Exclude Cameras
This property allows you to configure all cameras by exclusion. Click the plus to the right of the field to add a camera to exclude from the configuration.
Aspect Ratio
This property defines the relationship between the width and the height of the video frame.
Frame Rate
This property defines the speed of the video stream. Three options are available: Low, Medium, and High.
Resolution
This property specifies the pixel resolution of each transmitted frame. The actual pixel values for these three relative settings are defined in the video device.
Compression
This property specifies the level of compression used during live video streaming. The actual compression values for these relative settings are defined in the video device. Higher compression uses less bandwidth but negatively affects image quality.
Video Stream Fox
This property allows you to select or decline the use of Fox streaming.
- inherit
  This option causes a device to use the value for this property that is set at its parent component (the network component).
- true
  This option sends the video stream from the video camera to the station (controller) and then forwards it to the Workbench interface through the standard Fox connection. This overcomes firewall issues in the event that the video surveillance system is not exposed to the outside world on its network.
  
  NOTE: This assumes that the controller is exposed - otherwise you could not even connect to the station.
  
  If this option is selected, you should consider setting the resolution and Frame Rate to Low and the compression to High in order to preserve CPU usage in the station (controller).
- false
  This option sends the video stream directly from the video camera to the Workbench interface. Using this setting allows you to set the resolution and Frame Rate to High without having to worry about reducing the station (JACE) CPU - the station is removed from the equation. In either case, the client-side computer expends some of its CPU utilization to render the video on the screen.
- Timestamp Preferred
  Set this property to true to display and record a timestamp on the video.
- Interframe Timeout
  This property defines the time allowed for the video stream to begin in hours, minutes and seconds.
- Lo Frame Rate, Med Frame Rate, Hi Frame Rate
  These properties allow you to define the frame rate between 1 and 15 frames per second (fps) for each of the three frame rate options.
Layout
This property selects the number of video feeds to show on the display and the configuration of the display.
Hide Aspect Ratio, Frame Rate, Resolution, Compression, and Layout
These properties control whether or not these options are included for configuration on the left side of the Surveillance View.
Cameras
The camera properties identify the slot ORD for one or more cameras.
