  4. A list with ONVIF cameras in the network appears. Select the camera.
  5. Enter the ONVIF User name and ONVIF Password for your camera. If you obtained cameras from Noldus IT, the ONVIF user name is root and the ONVIF password is Noldus.
    TIP  To select another camera, click the Discover button to display the list with ONVIF cameras in the network.
    TIP  If you have several cameras with the same ONVIF User name and ONVIF Password choose File > Preferences > IP camera settings. Select Use default IP camera user name and password and enter the credentials. You can now skip step 5 and 6, the camera is detected automatically.

    For low frame rate recordings, it is important to lower the H264 Gov length too on the same screen, under Advanced settings. For 5 fps, set the Gov length between 5 and 10, for 1 fps recording between 1 and 2. A lower Gov length will result in larger files but better image.
    TIP  It is also possible to change the frame rate and resolution in the table with selected video devices.

    You may still need to adjust the Gov length for optimal results.
  9. Optionally, adjust the video quality, for example to decrease the video file size, but we recommend to only do this when problems with video quality or data transfer over the network occur.
    See Adjust advanced video quality options
  10. .Click Close when done.
  11. You may want to reverse the direction the camera moves with Pan and Tilt). To do so, select the checkbox Flip pan axis (horizontal movement) or Flip tilt axis (vertical movement) or both.
