obs help?

My newly acquired holiday home near Kiel, which is on the uninhabited week (is not rented) should be backed up.
Alarm with GSM module was eigebaut, wireless cameras installed. Only this should burglar noticed before the burglary and also be deterred. But these labels are good, glued to the inside of the discs they are deterred.
Now my problem: outside blinds on the windows!
Now the blinds are not fully closed to be visible on the upper floor to the sticker.
