I've got an old school Arlo setup. Base station and 5 cameras. I bought the entire setup used for $40 and have been very happy (about 3 months). One of the camera batteries recently died. I took it down, recharged/replaced the batteries, now it isn't synced and I can't get it to sync. I removed the device from the account and tried to add it new. Followed all instructions, and same instructions I used to originally set it up. No luck. Press sync on base station. Wait for blinking green. Press synce on camera. Flashes slow blue. Never goes to flashing fast blue to indicate synced. Just keeps flashing slow blue. Any ideas?
