Adhesive on sensors failing and sensors falling off

I have now had two window entry sensors fall off in the past week after being installed for a month.  Thankfully, the alarm hasn't been armed at the time.  What can I do to fix this problem or prevent it from happening again-- especially if I am not home.  I like the system but am getting very frustrated.  The last one to fall of popped apart from the bracket as well and the bracket is now missing-- now sure if the dog at it or what.  I need advice on getting this figured out.

There are many threads.

Go to local hardware store or home improvement store and get some genuine 3M Command strips.

Remount the sensors using those, but equally important is to be sure the surface is cleaned and dry and no flaking paint, etc. Then, also, be sure you firmly press and hold down for at least 30sec before letting off the pressure when reattaching.
