My camera won't show sd card recording and I get a prompt message asking for it to be initialised. I've had the camera 1 month working perfect I was able to watch playbacks. Today it's stopped working. I have 2 of the same cameras outdoor and both stopped recording or having the same problem. I have 2 indoor cameras using the same sd card 128gb samsung sd card and they working fine. 

I don't want to get ladders out if I don't need too. Can anyone help?
