Material specifications confirm a zinc alloy casing designed for standard 2-1/8 inch bore holes, though it lacks certified BHMA or ANSI security grading. Technical teardowns indicate the integration of a 508 DPI capacitive biometric sensor and a standard 3V-6V DC gear motor. Signal fidelity metrics for the Bluetooth 4.2 protocol show higher latency between app command and motor engagement compared to higher-bandwidth 802.11 standards.
Technical analysis identifies this hardware as a Tuya-integrated white-label product, sharing a chassis design with several budget-tier brands.
Performance data suggests the fingerprint module may exhibit a high False Rejection Rate in high-humidity environments. The 5lb total shipping weight and small-bore motor assembly are calibrated for standard residential use but may struggle with high-torque requirements of misaligned frames. Emergency access is provided via a USB-C jump-start port, an essential feature given the measured parasitic battery drain of the Bluetooth module.
If biometric consistency in varied climates is a priority, the Evanshow Smart Keyless Door Lock with Fingerprint serves as a budget-accessible entry point into keyless hardware.
This device is positioned as a foundational component within the keyless smart locks biometric keypad repository.
