Screen doors are the easiest and fastest way for an intruder to enter a house. They poke their finger through the screen, unlock the door snib, and they are in!! We see this too many times, and it can easily be prevented by using a door shield. A door shield correctly fitted to a screen door prevents the intruder from being able to turn and unlock the snib, hence keeping them out!! Homewatch Security Services stock a range of door shields, and can even install them for you if you wish.
