Digital Sentry systems running extremely 'sluggish' or 'slow' causing latency (lag) when configuring DS Admin.


  • The Digital Sentry system is operating very slowly with Windows or DS Admin commands taking a long time to respond.
  • CPU spiking up above 50%
  • OSD Time on camera works for a few seconds then stops.
  • DigitalSENTRY Video Service Service fails to start.

Product Line

Pelco Video Management


  • Digital Sentry versions 7.x.x
  • ENC5416 / ENC5516


  • Generally caused by configuration or communication failures.
  • Some cameras such as those with Sony Ipela drivers cause high CPU usage when configured for non-supported features such as camera-side motion detection.


There can be quite a few causes for this type of problem, here are some of the most common reasons.

Digital Sentry Services

  1. Verify the following Digital Sentry services are Started with a Startup Type = Automatic (ControlPanel > Administrative Tools > Services)
     - DigitalSENTRY Video Server Service
     - DigitalSENTRY Storage Service
     - SQL Server (DS_MSSQLSERVER)
     - IntegralSqlAgentService

  2. The default login account used for the services:
      - Username: DSNVSUser
    Password: Pelco123

    If the DSNVSUser account password has been changed in Windows, the services will need to be updated with the new information (DS Quick Setup > Next > Tools button > Change Service User Password)


DS Admin Connection Configuration

  1. Verify the systems hostname and IP address match what is listed in DS Admin > VAU > VAU Info > VAU Computer Name
  2. An easy way to confirm this using the command prompt:
      - Open a command prompt (Start > Run or Search Bar > type in CMD and click ENTER
    Type in the command hostname and then ENTER key, this will return the hostname of the system.
      - Using the hostname listed, use the command ping hostname (replace hostname with the name returned from the earlier command, with Windows 7, 2008 Server add a -4 to the end of the ping command) and take note of the IP address of the ping response.
  3. Open the DS Admin configuration utility (Start > All Programs > Pelco > DS Admin) and expand the Available Systems and VAU(s) folders.
  4. Just underneath the VAU(s) folder is the VAU system which has a computer icon, click on the system name under the VAU folder like a hyperlink to load VAU specific configuration tabs.
  5. Click on the VAU Info tab and verify the VAU Computer Name and TCP/IP Address match what is displayed in the command prompt results.

    Note: If using multiple Network Adapters, the ping response may come back with the incorrect IP address.  What is generally recommended is that the Primary Network Adapter should be the client or corporate network and the Secondary Network Adapter is used for the IP camera network. If the ping response shows the computername is bound to the IP camera network IP address, go to Network Connections and click on the Advanced dropdown menu (Windows 7 press the ALT key to show the menus), select Advanced Settings from the menu and verify under Connections: the client or corporate network adapter is at the top of the list.



DS Admin Storage Configuration

  1. Verify there is local storage activated for recording.
  2. Open DS Admin and navigate to the VAU (s), click on the system name underneath the VAU (s) folder like a hyperlink to load the VAU configuration tabs on the right.
  3. Select the Storage Locations tab and highlight the drive letter used for local storage under the Local Storage window.
  4. With the drive letter highlighted, verify there is a check in the checkbox Activate Storage Location. Note: C: drive should not be activate.

    Note: When using Network Storage >Copy To Network Storage Locations is check marked, at least one local storage drive must be enabled.

    Note: Make sure Selected Drive does not say offline.


DS Admin Video Input Configuration

  1. If using analog cameras with a hybrid Digital Sentry system, verify the correct capture card has been selected in DS Admin.
  2. If not using any analog cameras, make sure input devices are not checked active.
  3. Open DS Admin and navigate to the VAU(s) folder and expand, click on the system below the VAU folder (computer icon) like a hyperlink to load the VAU specific tabs.
  4. Click on the VAU Info tab.
  5. Under the Video Input Device section, verify the correct capture card has been selected for your system.
    DSSRV w/ENC5416 HP3000-16
    DSSRV w/ENC5516 ENC5516
    DSSRV2 ENC5516

    Note: Once the correct capture device is selected and saved, a restart of the DigitalSENTRY Video Server Service is required before video is displayed.

  6. Check VAU video input devices and make sure the correct number of cards is activated.

  7. Click on BRD1, BRD2, BRD3, BRD4 etc.  And disable video inputs that are not being used.



Verify IP camera compatibility

  1. If using IP cameras, verify the camera and motion settings are supported by the model and version number of the Digital Sentry product in use.
  2. Configure cameras to Server-Side motion detection that are not supported in Digital Sentry for In-Camera motion detection.  It is recommended to set cameras to In-Camera motion detection, when supported, to lower CPU usage.
  3. Disable firewall
