Philips Wi-Fi Smart Lock
Score: 72/100Rankings

The eufy Smart Lock C33 is a keyless deadbolt featuring integrated Wi-Fi and adaptive biometric fingerprint recognition that learns from handle grip usage. It offers multiple unlock methods including a keypad, app, and physical key, with a focus on easy 15-minute installation without drilling. It is ideal for front/side doors, garages, bedrooms, offices, short-term rentals, or guest rooms where quick biometric access and easy install matter over premium security or video features.

The Philips 4000 Series is a hub-free smart lock with built-in Wi-Fi, offering fast fingerprint recognition and IP53 water resistance. Its primary limitation is the low fingerprint capacity of only 20 users and the absence of an emergency power backup. It is ideal for small families or individuals seeking affordable, keyless entry with voice control capabilities.
