Sometimes, crimes are committed when no one is around to know. By the time anyone notices, the criminals are long gone. Nowadays, it is possible and easy to protect your home or office with alarm auto dialers.

An auto dialer is a gadget with passive infrared system that watches over any area you choose. When the unit is turned on or armed, the motion detector starts working. When movement is detected, a 105db security alarm will sound and the auto dialer will call up to 5 preset phone numbers.
