My motion detection is not working in the arlo camera, what should i do?

First check if the motion detection is turned on or off. if it is turned on the we can try to resync the camera.Or we can try removing the batteries and put them back.Reset the base station.If none of this works that means there could be some hardware issue.

First of all, check if your motion detection option is Turned On or not  in the camera settings

if yes ,then Try to resync the camera again with the base station

Try to remove the batteries from the camera and then sync again

Or try to reconfigure the base station again(means reset your base station and then configure it)

if none of the method is working, then it means that there is some hardware issue with the camera.
