A slow amber blink usually indicates a dead battery but you've tested that. You can try using AC power to the camera (assuming it's a Pro or Pro 2 camera, not the original wirefree camera that uses 4 CR123 batteries) to see if that works.</P> Sat, 23 Dec 2023 15:31:10 GMT jguerdat 2023-12-23T15:31:10Z https://community.arlo.com/t5/Arlo/VMB4000-can-t-sync-it-back-no-matter-how-I-use-the-sync-button/m-p/1940690#M93449 <P>Hi, I have the VMB4000.</P> <P>one of my camera stopped working, so I removed it from the app. Now the problem is I can't sync it back no matter how I use the sync button in the camera. The camera lights blue and turned off upon inserting the battery, &nbsp;but will never blink for the syncing. The battery is still good since I tested the battery with the other cameras that are working. I see occasional blinking of orange.</P> <P>Is this a hardware issue?</P> Tue, 26 Dec 2023 20:06:37 GMT https://community.arlo.com/t5/Arlo/VMB4000-can-t-sync-it-back-no-matter-how-I-use-the-sync-button/m-p/1940690#M93449 Cabrerahome22 2023-12-26T20:06:37Z https://community.arlo.com/t5/Arlo/VMB4000-can-t-sync-it-back-no-matter-how-I-use-the-sync-button/m-p/1940756#M93463 <P>Sounds like it's faulty.
