Smart Locks

A smart lock, like the Guardian Smart Lock, replaces your traditional deadbolt, offering keyless entry and remote access.

  • Key Features: Keypad entry, app control, auto-locking after a set time, and auto-unlocking when you arrive home (geofencing).
  • Why it's great: No more fumbling for keys! You can grant temporary access codes to guests, dog walkers, or contractors, and revoke them at any time. You can also check if you remembered to lock the door from anywhere.

Video Doorbells

See, hear, and speak to whoever is at your door, whether you're home or not, with a product like our Watcher Video Doorbell.

  • Key Features: HD video, two-way audio, motion alerts, and often package detection.
  • Why it's great: It's a powerful deterrent for package thieves and unwanted visitors. You'll never miss an important delivery, and you can answer the door from your couch or from the beach.

Sensors: The Unsung Heroes

Sensors are the eyes and ears of your smart security system. They are small, battery-powered devices that can trigger alerts or automations.

  • Contact Sensors: Placed on doors and windows, they alert you when one is opened or closed.
  • Motion Sensors: Detect movement in a room. Great for triggering lights at night or sending an alert if motion is detected while you're away.
  • Glass Break Sensors: Listens for the specific frequency of breaking glass, providing an extra layer of security.
  • Leak and Freeze Sensors: Placed under sinks or in basements, they can save you from catastrophic water damage by alerting you to the first sign of a leak.
