Problem: Most wireless alarm systems have an Achilles heel—if a burglar
smashes the keypad quickly enough, the police don’t get alerted.

Solution: SimpliSafe took the “brains” out of the Keypad and put them into a
separate Base Station, which is hidden somewhere in your home or office building.

• When an alarm is triggered, the Keypad beeps to distract burglars.
• Meanwhile, the Base Station stays quiet while it alerts the monitoring
  service (which takes just a few seconds). Once the alert has been safely
  sent, the Base Station will blast its sirens.

Summary: Unlike other wireless security systems, if a SimpliSafe keypad is
smashed, the alarm continues to function.
