Ring Spotlight Cam Pro Battery records black video every 2-5 mins

I recently purchased the Ring Spotlight Cam Pro Battery which was just released and shipped last week. I have installed at our front door and is running on battery. The wifi strength is - 48 rssi and we have fast, stable internet. The setup went fine, I have set motion zones, to record and only alert when people detected, and even turned down the motion sensitivity. The camera worked fine for the first few hours recording people and the notifications being sent. However after a few hours it starts recording 30sec black video every 2-5 mins. The camera at this point becomes unresponsive. The battery will drain very quickly also. When it doing this I also can not turn lights on and off via the app or watch live video whilst it is stuck like this. However the rssi is still - 48. And internet working fine. The only way to fix it is pull the battery out and in again, and then it works fine again for few hours. Then same thing happens again. Not sure what is going on and tried all the settings and options available. Any ideas? Regards, Phil.
