A high-speed fingerprint reader unlocks the door in under a second for convenient access. Additional methods include a touchscreen keypad, the eufy Security app, voice commands with Alexa or Google Assistant, and traditional physical keys for flexibility.
Clear 2K Video with Night Vision
The built-in camera captures sharp 2K resolution video with an f/1.6 aperture for better low-light performance. Dual motion sensors detect activity, and two-way talk allows real-time communication with visitors at the door.
