By installing eufy Security Smart Lock Touch & Wi-Fi, you will never have to worry about losing your key again and always have secure access to your home. The Smart Lock is powered by a Mabuchi motor that allows you to unlock your front door in less than a second. With a sensor area that is two times larger than on a smartphone, the Smart Lock is less likely to miss your fingerprint. Every time you unlock Smart Lock, the recognition rate improves because of the self-learning AI chip. This Smart Lock is weatherproof with an IP65 rating, so you can rest assured that your home is always secure. The Smart Lock is tested to last for 250,000 unlocks and is designed to still function after 30 years of use.
