Every IQ Panel 2 includes a bluetooth radio that allows you to pair up to five smart phones or tablets for Bluetooth Touchless Disarming. When your panel is armed in "away" mode you simply need to come within range and it will disarm automatically. It's secure, encrypted, and individually authenticated, and you can add automation rules like "when system disarmed by authorized user, unlock the front door and turn on the porch light" making it so your home is unlocked and disarmed as you approach it and you didn't have to do a single thing to make that happen.
Consider that for a moment: your home is secure, doors are locked, system is armed, and yet moments before you walk up your front steps, everything happens automatically for you. It's powerful, it's easy, it's the way any intelligent security and smart home system should behave.
