[KBA-00923] How to Customize Automatic Stream Selection in Security Center
This article explains what the Automatic stream is, how it is configured, and how it can be used in Security Center 5.1 SR1 to minimize the load on a network and maximize a workstation’s resources.
Automatic stream selection (a.k.a. the Automatic stream) is a Security Center feature that dynamically switches the stream shown in a tile depending on its size in order to minimize the network's load and maximize the workstation's resources.The three streams used by the automatic stream selection feature are: the Low Resolution stream, the Live stream, and the High Resolution stream. It will switch between the three when the number of diagonal pixels on a tile exceeds certain thresholds, as shown in the image below:
In other words, the Security Desk will display a low resolution stream on smaller tiles, while larger tiles will display a higher resolution stream.
More InformationSection A: Configuring the Automatic Stream
To properly use the Automatic stream, you need to configure three (3) distinct streams that will represent low, intermediate and high quality:
Configurations must be done on all desired cameras and workstations that will view them:
1. Configure the three streams for each camera
i. Open the Config Tool.
ii. Click on Video to open a Video task.
iii. Select the camera you wish to configure.
iv. Select the Video tab.
v. Configure the Low resolution, Live and High resolution streams.
vi. Repeat the steps above for all desired cameras.
2. Set the workstations to use the Automatic stream by default
i. Open the Security Desk
ii. Click on the Options button on the top right corner.
iii. Select the Video tab
iv. Set the Default live stream to Automatic and save your changes.
v. Close and re-open the Security Desk.
vi. Repeat the steps above for all desired workstationsThe Automatic stream is now set. As the user changes layouts, the tiles will get bigger or smaller. The Security Desk will select the most appropriate stream (out of the three configured) to display in the tile.
Section B: Customizing the Automatic Stream to Use Specific ThresholdsAs of Security Center 5.1 SR1, you have the option of customizing the Automatic stream to meet your monitoring requirements.
To customize the thresholds for the Automatic stream, you will have to modify the SecurityDesk.exe.gconfig file. You will have to do this for all workstations that you wish to configure.1. Customize the thresholds for the Automatic stream
- Depending on the version of Windows your computer is running, edit one of the
- 32-bit Windows: C:\Program Files\Genetec Security Center 5.X\SecurityDesk32.exe.gconfig
- 64-bit Windows: C:\Program Files (x86)\Genetec Security Center 5.X\SecurityDesk.exe.gconfig
- Add the following command line between <configuration> and
<automaticResolutionSettings highResolutionX="480" highResolutionY="320" lowResolutionX="320" lowResolutionY="240" />
- Save the file.
highResolutionX - Represents the number of horizontal pixels (x-axis) for the high resolution stream.
highResolutionY - Represents the number of vertical pixels (y-axis) for the high resolution stream.
lowResolutionX - Represents the number of horizontal pixels (x-axis) for the low resolution stream.
lowResolutionY - Represents the number of vertical pixels (y-axis) for the low resolution stream.For example, if you take the command line shown above, you get the thresholds shown in the image below:
At any point, if the diagonal pixels in your tile exceed 577 pixels, the Security Desk will display the high resolution stream in the tile. Any value below the low resolution threshold of 400 pixels will result in the low resolution stream in the tile. Finally, any value in between 577 and 400 pixels threshold will result in the intermediate (Live) stream.
To increase or lower these thresholds, change the values in the command line and save the SecurityDesk.exe.gconfig file.
