When your camera turns on Night Vision it moves a filter over the camera and can cause a temporary clicking sound. If it continues to click, you can try the following steps:
- When you hear the clicking, open up the Live Stream of the camera to check if it is cycling Night Vision On and Off.
- Cycle the Night Vision settings through Auto
, Off 
, and On 
to see if it will stop the continuous clicking.
If the issue persists, please create a recording of the camera clicking on your phone and submit a contact us with the footage.
