Two of the popular home safety products that I knew of are the HomeSafe Wireless Home Security System and the TeleSpy Intruder Alert. They are quality and reliable alarm systems.
My bungalow is secure with the HomeSafe Wireless Home Security System. When its sensors detect motion from the windows and doors, it would sound off a shrill alarm and automatically dial pre-programmed numbers to alert the owners and the base.
You need a landline telephone to activate this system. The window and door sensors are equally effective even at 250 feet away while the motion detector has an 8 yard range. With the remote control, I can activate or deactivate the system. I usually do that when I have visitors.
