Motion detection is based on heat signature so the camera can discern the difference between, say, a spinning fan, a small dog, and an actual
moving person who's breaking in to your home. Recently added, Alexa voice control lets you arm your system or check on its status on Amazon Echo
devices. Enabling the SimpliSafe Home Control skill in the Alexa app is simple, and commands like "Alexa, tell SimpliSafe I'm leaving" to arm the system in Away mode, "Alexa, tell SimpliSafe good night" to arm the system in Home mode, and "Alexa, ask SimpliSafe if my home is secure" to get system status worked well in testing. There was little lag between the voice command and the base station announcing status or changes in system modes. The Alexa integration only works with the new SimpliSafe hardware, and the system can't be disarmed via voice for obvious reasons. With the monthly Interactive Plan, you can use SimpliSafe's Online Dashboard or mobile app to control the system, including arming and disarming it.
