DIGITAL SENTRY NETWORK SPEED SIMULATION
This procedure provides the parameters for simulating DVR-to-client network connection speeds by changing configuration parameters within
the DSAdmin utility. It is intended for demonstration purposes only and is not currently intended for use on functioning installed systems. The
result of this simulation is realized when the DVR has only one connected client running on a separate computer.
To simulate various network speeds, complete the following steps:
1. In DSAdmin, open Configuration Parameters and select PacketDelayMS. The default setting is 0 (zero).
2. Select PacketSize. The default setting is 65000.
3. Change PacketDelayMS and PacketSize to the following settings:
4. Restart Digital Sentry services for changes to take effect, and then reconnect using the client computer.
5. You can view monitor network utilization in Windows Task Manager on the DVR or the client computer.
6. Reset to the default settings and restart Digital Sentry services when you are finished.
CHECKING FOR VIDEO FILES
The following instructions detail how to verify that video is being recorded:
1. Open My Computer on the VAU.
2. Open the first available data drive (usually D:).
3. Open the Video directory. If the Video directory does not exist on a drive, video files are not being saved to that drive. If so, check another
data drive.
4. In the Video directory, select Details from the View menu.
5. Click the Modified column to sort the video files by the time and date they were captured. To sort the most recent files to the top of the list,
click the Modified column again.
6. Refresh (press F5) to verify that the most recent files are being updated. The best way to do this is to check the file size; if file sizes increase
when you refresh, the video files are being updated.
7. If the files in the first drive are not being updated, repeat these steps on the other data drives.
8. Close My Computer.
NOTE: You must be sure to close My Computer (Windows Explorer) after you check for video files. If My Computer is left running, you will
encounter a significant performance hindrance, especially if the selected folder contains many files.
