Had no problem syncing the first three cameras to the base station yesterday, but I went to sync the fourth camera today, and it just won't work. I double and triple checked the batteries, and the polarity, yet it still won't work.</P> Tue, 27 Sep 2016 22:43:49 GMT casgeek 2016-09-27T22:43:49Z https://community.arlo.com/t5/Arlo/Can-t-get-fourth-camera-to-sync-to-the-base-station-Model/m-p/1101686#M9568 <P>We just purchased the four camera system yesterday.

Try a factory reset on the base using the reset button on the base until the LEDs flash amber and try again.</P> Thu, 16 Jun 2016 20:06:35 GMT https://community.arlo.com/t5/Arlo/Can-t-get-fourth-camera-to-sync-to-the-base-station-Model/m-p/1101717#M9569 jguerdat 2016-06-16T20:06:35Z
