Hi all. 
I bought 3 x c425. They were working great for a week then they updated to new 1.2.23 firmware ( was 1.2.21 ) and now they don't work properly. It now sets off when my car is just sitting there, alerts all the time. 
They also now set off a alert notification and alarm off if I open the app and tap on a camera I want to view. Eg. Carport camera, open it and it sets off the alarm and notifications come through instantly. 
 

how can I go back to a previous firmware? It worked perfect before this!

cheers.
