This 21st century security device can save you hundreds of dollars a year in monitoring fees.  It can "guard" your home or office seven days a week, 24 hours a day.  If an intruder is detected within its large detection area (20 ft long by 90 degrees) it will sound a powerful 125 decibel  to scare away the would-be intruder and alert those inside to the attempted entry (the alarm feature can be disabled if you prefer a silent alarm).

Up to three phone numbers are automatically dialed and your pre-recorded message (up to six seconds long) is played.  You could program it to call your neighbor, the police, and your cell phone and play a message like, "this is John Doe, an intruder has been detected in my home located at 123 Maple St.." 

Features include simple operation (can be installed by anyone in only minutes), arms and disarms using a keypad (you set your own security code), and entry and exit delays help prevent false alarms.  Two alarm system warning decals are included.  Uses on your current phone line the unit comes with a line splitter (an additional line is not required) and 6 feet of phone cable.  This alarm measures in at 6 1/2" x 2 1/2" x 1 5/8". Requires four  'AAA' batteries that are not included.
