Sound captured is a bit muffled, but certainly audible, though the camera does not currently support two way audio. Night vision footage is clear and motion detection sensitivity can be adjusted in the app. 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. The Dashboard also lets you view your System
Event Log, change your PIN, assign up to four guest PINs, and choose an optional Duress PIN, to use when an intruder is coercing you to disable the alarm. Enter it, and the alarm will stop sounding, but SimpliSafe will immediately send the police. You can also tweak settings like siren volume, entry and exit delay time, and manage and rename sensors in the Dashboard.
