arlo pro 2 camera night vision works worse after charging

[hopestay]

It happened twice on my two arlo pro 2 cameras that after taken off the wall and charged fully, the night vision worked worse. I would not say they are not working but it is no better than not working. That is, they had night vision in the first 2 to 3 seconds then you can barely see anything in the cameras as if they were turned off automatically in 2 to 3 seconds. It happened to my first camera last Friday and I showed the recording to the arlo technician, he concluded that it was the hardware problem and assigned me an RMA number then this noon I mailed it back for an exchange. The same thing happened again this evening after I charged the second camera. I did the same procedure as to the first camera: removed the camera with arlo app; pull off the battery from the camera and put it back after 5 minutes; re-synced the camera to the base; even I restarted the base. Still the night vision did not work, and the symptom is the same as the first camera, so I doubted if this time it is a hardware failure again to the second camera.

For information, the firmware of the cameras is 1.125.11.4_29092 (hardware: H3), and for the base is 1.12.0.1_27940 (hardware: VMB4000r3), both of the firmware are up to date.

Also the recording of the first camera (RMAed) is: https://arlo.netgear.com/hmsweb/users/library/share/link/D56C3930F4184EA2_201903
the recording of the second camera (tested tonight) is: https://arlo.netgear.com/hmsweb/users/library/share/link/B5E7E82374B9C067_201903

Please advise, thanks in advance.

It's that big glowing orb in the middle of the frame that's causing this. The camera determines it's at night but the autoexposure determines that there's enough light to switch to daytime recordings - see the switch to color? Either turn off that light or reposition the camera with the light outside of its view.

Thanks for the suggestion.

But that should not be the only reason, I think Arlo night vision sensor has its algorithm to make decision how night vision is triggered, you can see this video which has a slight different position of the camera and it was with the light in the view: https://arlo.netgear.com/hmsweb/users/library/share/link/119E66B523CC9966_201903

However, I solved this problem by re-positioned the camera with experiements to make the camera night vision working.
