Access control system

The access control system is a brand-new access management method: allow persons with authority to enter the designated area, and reject persons without authority. The protagonist of the system is the card reader or password keyboard installed on the door side. They transfer the read data to the local controller, and confirm whether they can pass according to the database compiled in advance.

CCTV

CCTV is an effective tool to prevent the loss of items, capture important suspects, and record the entire incident process in modern collective activity venues. The complete monitoring system includes: camera, matrix, picture splitter, control equipment, and digital video recording. ICD has extensive practical experience in this field. Whether it is a surveillance system for small offices or a large-scale complex surveillance system, ICD is also trustworthy.

Biometrics

Biometrics uses computers and advanced scanning technology to make use of the uniqueness of certain physiological characteristics of the human body for identification. With the development of PC technology, the speed of PC has made remarkable progress, the price is no longer expensive, and the application of biometric technology in access control is more and more accepted by people.

Fingerprint recognition

Fingerprint recognition is based on the fingerprint of a single finger.
Fingerprint recognition is an image analysis of the fingerprint of a single finger. The registration time takes 5 seconds, and the recognition time only takes 1 second. The fingerprint machine also supports proximity cards, magnetic media cards, smart cards, and strip cards. The standard capacity of fingerprint storage is 512 people, up to 32,000 people.

Palm recognition

The palm shape recognition machine scans and records the three-dimensional images of four fingers and part of the palm as the recognition object.

Iris recognition

The iris is more unique than fingerprints, and even twins will not have the same iris.
