What happens if you try a different power adapter? The adapter that comes with Cam Pan v3 has 5v ⎓ 2A output but isn’t an outdoor-rated adapter, so I wonder what would happen if you tried a power adapter with equivalent output. (Note that other Wyze Cams—such as Cam v4 and Cam OG—ship with 5v ⎓ 1A adapters and don’t have the power requirements of Cam Pan v3, with its motors, so be careful that you’re not trying to power Cam Pan v3 with one of those.)
You still haven’t defined “drop”, so I’m interpreting that as a connectivity issue. When I got my first Cam Pan v3 I had frequent Wi-Fi disconnects and the camera would fail to regain its connection unless I power cycled the camera. Eventually that seems to have been remedied with subsequent firmware updates, so I’d make sure you’re current with those on your Cam Pan v3s.
I’ve also read suggestions in the Forum that Cam Pan v3 has an inferior antenna and reports that a (non-Pan) Cam v3 at the same location will maintain its signal at the same location where a Cam Pan v3 might have issues. I’m not suggesting that you replace the Cam Pan v3s; I’m just relaying what I’ve read.
What troubleshooting have you attempted, and what did Support say when you contacted them?
