Arpha 211791: 5-in-1 smart security
Stop guessing who's at your door. This ARPHA smart lock lets you see, hear, and grant access from anywhere. When the doorbell rings, you get an instant alert with a live HD video feed right on your phone. Talk to a delivery driver through the two-way audio, or remotely unlock for a family member.
- Five ways to unlock: Fingerprint, keypad code, app control, or physical key. No more hiding a spare.
- Auto-lock: Set a timer (10 seconds to 30 minutes) so you never accidentally leave the door unlocked.
- Weatherproof: Rated IP65 and tested from -31°F to 158°F. Works through rain, snow, and summer heat.
- Easy install: Fits standard US doors with just a screwdriver. No wiring needed.
Note: WiFi is 2.4GHz only. The camera only activates when someone presses the doorbell — not continuous recording. Ideal for monitoring deliveries and guests without battery drain.
