That is the biggest problem with these cameras is people think they are magic. All cameras need light, simple physics - either white light or infrared, but this camera cannot see infrared so it needs white light.
If there isn't enough light, then the camera cannot see an object for motion detection.
Some of the firmware allows it, but Hik removed the ability in updates because like I said if the light isn't on, then the camera has trouble seeing an object and people were getting mad thinking the camera was defective because it wasn't triggering for motion. Plus when the light would kick on, then there is a momentary exposure issue and in some field of views the camera is quickly blinded during the money shot. But they bounce back and forth on if that is a feature or not.
Here is a video on how to set it up if your firmware allows it. So hint, if it does, then do not update the firmware or you may lose it again....
And if you find that the camera sucks without the light, then return it and get a camera that can see infrared...or tell your neighbors to suck it and keep the white light on all night LOL.
