Arlo Pro 2 cameras not syncing

[2Arlo2old]

I purchased a four-pack of Arlo Pro 2 cameras a few years ago. Initially we only needed to sync two cameras and so the base station and two cameras worked very well.

Recently we've tried to now sync the remaining two cameras however they are not picking up. We've charged them overnight, swapping batteries regularly.

Anything else we can try? Is the fact that we didn't use the cameras until now the cause of them not working?

Other than sync'ing thru the app/program..the Pro/Pro2 is one of the few that can be sync'ed manually.

( guessing you have a 4000 or similar base )

Make sure battery is charged/ installed ( led should flash once when inserted )

Within 3 feet of base, quickly press the sync button on base ( led should flash on base ) then press the sync button on camera.

If the camera goes from slow blinking to fast , the camera sync'ed to base.
