High CPU usage when recording Oncam Grandeye IP cameras using In-Camera motion detection.

Issue

The CPU usage on a Digital Sentry system can slowly climb to around 80% usage when running Oncam Grandeye Evolution 360 cameras with "In-Camera" motion detection.

Product Line

Pelco Cameras, Pelco Video Management

Environment

  • DigitalSentry 7.7.309 and later
  • DSSRV / DSSRV2
  • DS NVs
  • Oncam Grandeye EVO-05 360 1.3 to 1.8

Cause

Software issue with DS and Oncam Grandeye EVO-05 internal motion detection.

Resolution

The DSSRV supports a maximum of 6 Oncam EVO-05 IP cameras and the DSSRV2 supports a maximum of 8 Oncam EVO-05 IP cameras.

Recommend Digital Sentry server software version 7.17 or greater.


The Oncam Grandeye EVO-05 full size will need to be updated to firmware 1.9.12 or greater. 

  1. Download the firmware here

    Note: It is important to carefully follow the instructions in the release notes for this firmware upgrade, the release notes are included in the download.

     
  2. Use the Oncam Configuration Tool  to update the firmware on the camera.  




    Allow 3 to 5 minutes for the camera to update, after the firmware update a factory default of the camera is required.

     
  3. Using the Oncam Configuration Tool, select Evolution-05 Camera for the Camera Type and then check the box for the camera once it is detected. Under the "Camera Configuration" tab click the drop down next to "Send command to camera".  Select "factoryreset.cgi" and then click the Send button.


    Note: Factory defaulting the camera will result in the IP address being reset.  Default is DHCP = ON and if no DHCP server is found the camera will assign itself an IP address of 192.168.0.200.





     
  4. Access the cameras web interface and navigate to the REGIONS option at the bottom of the page.
    1. Change the REGION TYPE: to Motion Detection.
    2. Type in a name for the motion zone in the Name: field.
    3. Click the Draw button, select the regions desired...each time the mouse is clicked a link is drawn between the last mouse click and the latest.
    4. Once the zone is configured select Save.

      Note: With EVO05 v1.9.12 or greater firmware, by default In-Camera motion is enabled and detecting the full image.  If there were previous motion zones configured before the upgrade they will be used.
