Complete system troubles

I have a doorbell pro (wired) a spotlight cam (battery) and a Gen 1 and Gen 2 chime...and since **'the big freeze'** in December...my system has become extremely troublesome after two/three years of no issues at all. One battery in the spotlight cam has died - presumably due to the cold weather - having previously worked perfectly...no longer holds a charge...so i'm resigned to have lost that. Amongst a load of other issues with notifications and chimes not sounding, my main issue is my spotlight cam disconnecting and going offline 3/4/5 times a day. As it's mounted outside, It's about 10-12 feet away from a BT wifi disc on the other side of a wall - and you'll see from the images attached...it does receive a good connection. (Which admittedly, for some unknown reason, fluctuates.) **The question here...is as to whether the cold weather has additionally broken something else within the spotlight cam...as nothing else has changed?**
