Smart lock fit
Compare retrofit locks, replacement deadbolts, and handle-style options before changing hardware, keyways, or keypad access on an existing door.
Forget juggling a separate doorbell, camera, and lock. The Havion Deadbolt Smart Lock combines all three into one flush-mounted unit. It is built for the homeowner who wants a cleaner entryway and a simpler security routine.
The 2K QHD camera with a 170° field of view captures visitors from head to toe and packages left on the ground. The PIR and radar motion sensors work together to cut false alerts by 95% — so you are only notified when someone actually approaches, not when a car passes by. Use the two-way audio to tell a delivery driver where to leave a package, even when you are at work.
Access is flexible: use a fingerprint, a code, or a physical key. The app lets you create temporary codes for the dog walker or the house cleaner. With 32GB of local storage, you do not need to pay a monthly fee to save clips. The 10,000mAh battery lasts up to 270 days per charge, and an emergency charge port is there if you forget. It works with Alexa and Google Assistant for voice control. Install it on a 1 3/8-inch to 2 1/8-inch door in about 30 minutes.
