All of the systems we've tested feature an app that lets you use your smartphone as your command
center to arm and disarm the system, create rules, add and delete components, and receive push notifications when alarms are triggered. Most apps also allow you to do things like view live and recorded video
, lock and unlock doors, change thermostat settings, and silence alarms. Some apps will even use your phone's location services to automatically arm and disarm the system according to your physical location. The more expensive systems usually come with a wall mounted panel that acts as a communications hub, with a touch screen display that allows you to do everything the app does. The display lets you communicate with a professional monitoring service when an alarm is triggered and view video from any of the installed security cameras. While many systems use wireless components that are installed using double sided tape, some high end systems use components that require professional installation.
