Wall mount does not swivel, thereby limited mounting options.

Unlike other products, the wall bracket is NOT mounted. This limits the range of applications in my opinion a strong, because you should be as high hanging the unit out of reach for protection against burglars. But this does not go here, because you can not judge down the device. For this reason, I have the unit also sent back.

Alternative:
I therefore recommend the model King SEC-APR20, the practical costs the same but has a swivel wall bracket. This mounting to an inaccessible place is possible, and the unit can be directed downward. Note, however, that here again not a very steep angle can be adjusted downward, so that this device can not be arbitrarily high hanged.
