Motion detection stops working

IBBoard — Thu, 17 Jul 2025 18:13:56 GMT

I've got an Arlo Pro 4 connected to a VMB5000. There's an SD card in the hub and the Pro 4 is recording to it. We've noticed a few times that the camera stops recording and seems not to trigger on motion, but a few "remove, reset, sync" cycles normally fixes it.

Now, however, it's just absolutely refusing to do motion detection, even in the test mode. There's no orange light and no recording.

I've tried:

The "do these steps in EXACTLY this order" sequence repeatedly
Doing the steps but leaving the camera powered down for a day in the middle
Doing the steps after fully charging a camera (that was already on 90%)
Doing a full factory reset of the Hub and reconnecting the camera
Removing and re-adding with a different name
Cranking the motion detection all the way to max
Making sure the camera is clean
Checking the "Arm Away" rules - the app is permanently in that mode and the camera is set up for motion detection

I'm not using activity zones. I'm not using automation. The camera and the hub are on the latest firmware. The camera has decent signal and is within ten feet of the hub through thin, modern-build house walls. All of this worked before, I'm just trying to get a motion detecting camera to detect motion again!

(I've just enabled "Audio detection" and that seems to be working... but not motion detection)

My older camera still works fine. But it worries me that some of these "why has my camera stopped doing motion detection" threads go all the way back to 2022 😐

Did you try a hardware reset of the camera?

remove it from the account
open the housing and press the button inside until the camera LED flashes orange (~15 seconds)
add the camera back to the account
