Simplisafe Keypad Replacement Problem: Most wireless alarm systems have an Achilles heelif a burglar smashes the keypad quickly enough, the police dont 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.
