IP Cameras Producing Constant Humming or White Noise
Last updated: Oct 29, 2026
Problem
IP cameras installed in the lab begin producing a constant humming or white noise sound without a clear cause.
Details
Affects wall-mounted IP cameras in Viso-monitored environments. The noise begins unexpectedly and is not related to Viso software settings. A camera-level reboot resolves the issue.
Solution
1. Access the affected camera's onboard menu (typically via the camera's physical controls or web interface).
2. Perform a reboot of the camera directly from the onboard menu.
3. Wait for the camera to fully restart and verify that the noise has stopped.
4. If the noise persists after reboot, check the camera's audio settings to ensure audio output or noise reduction features are correctly configured.
5. If multiple cameras are affected or the problem recurs frequently, contact Noldus Support to investigate a potential hardware or firmware issue.
