When using the fingers, they need only to place their fingers on the fingerprint collector. On the collection window, you can complete the unlock task and the operation is very simple. In addition, traditional mechanical locks, identification cards, and code locks are prevented from being lost due to the loss and misappropriation of keys, the forgery of identification cards, or the decipherment of code locks. At the same time, the system also has a screen Chinese character display function, thereby enhancing the protective measures for access control. Achieve security management functions.
Second, facial recognition access control
Facial recognition is also called face recognition, face recognition, face recognition, etc. The following are all called face recognition. Areas protected by security can identify the identity of the person trying to enter through face recognition. Face recognition systems can be used for business, residential security and management.
Facial recognition is based on the human facial features to identify the technology, including standard video recognition and thermal imaging technology.
Standard video recognition records the facial features such as the eyes, nose and mouth of the person being photographed through a common camera, converts it into a digital signal, and then uses a computer for identification. Video facial recognition is a common form of identification and is now widely used in public security.
Thermal imaging technology primarily produces facial images by analyzing the thermal radiation generated by facial blood. Unlike video recognition, thermal imaging does not require a good light source and can be used even in dark conditions.
