If your device does not support ONVIF, see [Select devices that do not support ONVIF in MediaRecorder](https://bookstack.noldus.com/link/489#bkmrk-page-title) instead.
## Prerequisites

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[ ](https://bookstack.noldus.com/link/409#bkmrk-page-title)> **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](https://bookstack.noldus.com/link/488#bkmrk-page-title)
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.
