McCallister Guard

McCallister Guard protects your home through deterrence rather than just alarm. When a sensor detects an intruder, it does not simply sound a siren — it makes the house appear occupied by triggering dog barks, flashing blue police lights on connected screens, silhouettes in the windows and realistic lighting patterns that mimic a home in full activity. The goal is to make an intruder turn around at the door, before anything happens. At night, a quiet Perimeter mode monitors only the exterior doors and windows you choose, and sends a notification to your phone if someone tries to enter — without waking the household with a siren. When you leave home, full protection takes over: deterrence starts in a zone away from the intruder, escalates automatically to a full siren alarm if they do not retreat, and a presence simulation keeps the lights cycling to make the house look lived-in. Everything runs locally on your Homey Pro — no subscription, no cloud service required.
