Create security systems for your home, retail shop, shed or garage etc. Magnetic door or motion sensors can alert when doors are opened or when someone approaches. Ideal for shed security or to assist the infirm to notify before the doorbell is pressed.

Something as simple as a front door being left unlocked can allow for an uninvited visitor to slip in undetected and steal a small item such as car keys, wallet or mobile phone whilst the homeowner is upstairs or in another room.
