Face recognition technology is based on the facial features of a person, and recognizes the input face image or video stream. The recognition process first determines whether there is a human face. After identifying a human face, scan the position, size and position information of each main facial organ of each face, and then further extract the identity features contained in each face based on this information , And compare it with known faces to identify the identity of each face. Compared with fingerprint recognition, its main advantage is that the face recognition lock can actively obtain user information without user contact.

solid and composite rivets use in Medium and Small size contactor,switches, Micro switches relays. Small circuit breakers
Bimetal Rivet
Pure silver contact:
Features:
(1) Pure silver has extremely high electrical conductivity
(2) Very low contact resistance
(3) Easy to solder
(4) It is easy to produce, so silver is an ideal contact material
(5) It is one of the most widely used materials in small capacity and voltage
AgNi contact:
Features:
(1) AgNi contact material contains 10% to 40% Ni
(2) Produced by powder metallurgical production, with low and stable contact resistance,
high hardness and mechanical strength
(3) Material transfer in case of DC is very low
(4) High electrical and thermal conductivity
(5) With very low arc erosion. On making higher current, normally asymmetric pairs
with AgC contact materials are applied
(6) Wire of solid and composite rivets produced by powder sintering-extruding methods
AgSnO2 contact:
Features:
(1) AgSnO2 is the ideal material of AgCdO and has excellent properties of contacts
(2) AgSnO2 has higher thermal stability
(3) AgSnO2 has higher resistance against welding and erosion than AgCdO material
(4) Non-poisonous. So it is a new material which is empoldered and developed actively over the world
(5) For AgSnO2 contact material, the contact resistance can be controlled within
the limited range by putting in a small amount of additive of special metal-oxide
(6) In this aspect, contact materials produced by powder metallurgy processing method have higher resistance against arc erosion and less arc bumming than those produced by oxidation processing method
AgZnO contact:
Features:
(1) ZnO, one type of material in AgznO contact, has comparatively higher thermal stability
(2) The welding resistant and resistance against arc erosion of the contact making
ZnO material a higher product
(3) The AgZnO contact material has higher welding resistance and low arc erosion
with strong magnetic arc blowing under large switching capacity
(4) AgZnO contact material is innocuous and has no pollution to the environment
(5) AgZnO contact material is mostly suitable for contactors and circuit breakers
with large capacities
AgCdO contactt:
Features:
(1) AgCdO is a kind of most important contact material among silver metal-oxide materials, and it is widely used for low-voltage devices
(2) When the temperature is higher than 900oC, CdO is sublimated and the contact surface is cooled down in order to reduce and even extinguish
the arc energy. This method can increase the resistance against welding
(3) Contact materials produced by powder sintering-extruding methods have higher
density and low resistance rate(4) It also has higher welding resistance and uniform arc erosionInner

Faced with the elderly and children, their fingerprints cannot be accurately identified due to aging and unformed fingerprints. For some adults, their fingerprints are inherently fuzzy, or they will lose the accuracy of fingerprint identification after sweating. sex. The face recognition lock has no related troubles, and it can be easily recognized by both the elderly and the children.
