Video Views Definition |
Once the video server is defined and its cameras identified, operators can define video views that will be displayed in the Video desktop for viewing and monitoring purposes. EntraPass operators will then call previously configured presets and patterns.
EntraPass Devices (workstations, gateways, sites, controllers, etc.) can be associated with video views. Later, the video view can be selected in the components definition in order to display the component in the video view.
Defining General Parameters for a Video View
1 - Select the Video view button from the Video toolbar. The Video View window appears with the General tab enabled.
2 - From the Video view drop-down list, select a video view (or click the New button to create one), then assign it a name in the language section. If the system is running in two languages, you have to give a name in each language.
3 - From the Video server drop-down list, select a video server type (Intellex, HDVR or TVR).
4 - From the Default size on video drop-down list, select an appropriate size for the image that will be displayed: you may choose to select a smaller size if you have to display the Video window with another window.
• Large : 1024x768
• Medium : 800x600
• Small : 640x480
• Tiny : 400x300
• Last used : displays the size that was previously displayed in the Video desktop.
5 - From the Default size on graphic drop-down list, select a size for the image that will be displayed on the system graphics (Large, Medium, Small, Tiny, Last used).
6 - Specify the Refresh rate percentage using the Up/down arrows.
NOTE: The Refresh Rate Percentage is related to the image compression/quality. The image quality impacts the system performance: the higher the quality, the lower the compression and the lower the system performance will be. If you set the Refresh Rate to high (> 80), the compression will be low. As result, the application will use a larger network bandwidth. This may result in a slower process. The following table shows the recommended options:
| Quality | Description | Result |
|---|---|---|
| 80 and Over | Super quality | Images are recorded at the highest image quality, using the lowest level of compression. This setting requires the highest amount of storage space and network bandwidth. |
| 50 | Normal, Default | Images are recorded at normal image quality. This setting provides a balance between compression and storage space requirements. The smaller, more subtle changes between images are ignored. |
| 40 | Low quality | Images are recorded at low image quality, using the highest level of compression. This setting requires the lowest amount of storage space and network bandwidth. |
7 - Check the Re-initialize video view delay (mm:ss) option if you want the system to refresh the displayed image. If you check this box, the displayed image will be automatically updated when the specified delay is elapsed. This feature is very useful if the defined camera view includes patterns or presets.
8 - From the Video control section, make the appropriate choices:
• Show overlay Intellex and HDVR only) : check this option if you want the camera identification (camera name and server) to appear in the Video desktop.
• Show camera control: check this option for use with dome cameras. Selecting this option allows operators to control a dome camera. It is not available with fixed cameras.
• Show metrics (Intellex only) : this option enables the system to display the number of frames per second (Fps) and the number of bits per seconds (Bps) for the selected camera. The information appears in the upper section of the Video window (and in the Video desktop).
• Auto-hide text (Intellex only) : if this option is checked, the system will not display the information related to a camera.
• Enable image zoom (Intellex only) : check this option if you want to display the zoom value for the selected camera.
9 - Check the Enable video pattern box to alternate video images in the Video window. If you have defined a 2X2 view, then the video pattern will be composed of four images alternating in the video display according to the delay specified in the Camera display delay field. If you do not check this option, the video view will display all the cameras simultaneously.
NOTE: The Enable video pattern section is enabled once components have been assigned to the video view.
10 - Check Delay before launching sequence (m:ss) box to specify the transition delay before the images start alternating in the Video window.
11 - Specify the display delays for Cameras , Presets , Patterns and Graphics .
NOTE: These delays indicate the time interval during which a video or graphic appears in the Video display before it is replaced by another. Refer to the following table for the minimum/default delays. The maximum delay is 9:59 seconds.
| Delay | Minimum (sec.) |
|---|---|
| Delay before launching sequence | 2 seconds |
| Camera display delay | 3 seconds |
| Preset display delay | 5 seconds |
| Pattern display delay | 10 seconds |
| Graphic display delay | 5 seconds |
12 - Select the Details tab to view data about the selected view: video servers, cameras, and when applicable, camera presets and patterns.
