Description

Technical Field

[0001] The utility model belongs to the technical field of access control iris recognition, and particularly relates to a lifting and adjusting mounting frame for access control iris recognition. Background Art

[0002] With the continuous advancement of science and technology, people's awareness of security has gradually increased, and access control devices are used more and more widely in our lives. Access control devices can effectively prevent outsiders from entering and exiting at will, making a huge contribution to personnel management. Iris recognition access control devices are also gradually appearing in our lives. Iris recognition mainly relies on iris cameras.

[0003] Access control iris recognition cameras are usually fixed on a certain device, and the height of the device cannot be adjusted. People of different heights cannot be quickly recognized successfully during iris recognition due to the height difference with the device, which brings inconvenience to people. Therefore, we propose a lifting and adjusting mounting frame for access control iris recognition. Utility Model Content
