Mines spot on mate tbf, but my router is very very good, i had a different router a while back but my new one is really good and the rssi signal is so much better on the ring cameras nowMaybe its just me but I have the ring spotlight cam and generally find the quality of the camera to be average even during the day time.
Maybe because its a bit far from the router which may be the issue.
The motion detection on them can be hit and miss and have to get the sweet spot otherwise you get motion detections every few minutes which is a ball ache.
Do agree the alarm siren feature on the app is very handy for situations lol.
There decent cameras tbh but wouldnt get them again personally. Got them new of my mate dirt cheap at the time so was worth it then.
Mines all hard wired to a box in the garage mate, cba with the batteries.Ye dont use third party router just the VM one tbh mate.
Only thing bugs me have to keep charging the batteries as does drain alot.
Invest in a new router you won't regret it
