Embodiment Construction

[0018] The visitor system registers fingerprints through the fingerprint visitor system. When the fingerprint collection unit 3 is abnormal, the CPU will switch to the fingerprint entry system, through which the two visitor systems operate alternately and are combined with the image visitor system, after the fingerprint is passed, the CPU calls out the image in the resource data pool to compare with it , The visitor information is entered only after the image similarity reaches the preset value, and the visitors are diversified, effective and accurate.

[0019] The visitor system in the present invention can also flexibly select the entry mode of the visitor system according to the actual situation when installing and using the fingerprint collection unit, and when the fingerprint collection unit is in normal operation, it can send a prompt through the voice broadcast unit, which is convenient for visitors personnel use.

[0020] The above descriptions are only preferred impl...
