Magnetic lock refers to the lock which directly USES fingerprint as the input signal and identifies and processes relevant information to control the opening and closing of mechanical actuator. It mainly consists of the following two parts:
Fingerprint identification and control: it consists of a fingerprint acquisition device, an operational control unit and an input/output circuit.
Lock body and shell: it consists of mechanical lock body, shell, handle, etc.
The main functions of magnetic lock are: fingerprint login, fingerprint deletion, information preservation, permission management, alarm, emergency unlock, etc. In addition, many manufacturers also add some additional functions, such as integrated doorbell, voice prompt, Internet connection, telephone alarm, etc., high-performance magnetic lock is also equipped with LCD and other human-machine dialogue systems, with a high level of intelligence, with guidance operation, inquiry door opening record, built-in parameters, setting status and other functions.
The technical parameters of magnetic lock mainly include fingerprint capacity, photoresist resolution, verification and comparison time, rejection rate, false recognition rate, identification Angle, working voltage, working environment, etc.
1. The maximum storage capacity of fingerprint can be registered by the fingerprint head.
2. The optical resolution optical fingerprint head is accurate in reading fingerprint images, and the higher the theoretical resolution, the better. Currently, the light sensitivity resolution of fingerprint head is generally 500DPI(dots per inch).
3. Verification and comparison time is also called matching time, which is the time difference between fingerprint acquisition and fingerprint matching results.
