Summary of Face Recognition Time Attendance Machine
Face recognition time attendance machine is a new type of storage time attendance machine. It only needs to collect employee’s face image in advance and create files. When employees stand in the recognition area of face recognition time attendance machine on and off work, the time attendance machine will quickly Record attendance status and keep records.
The face recognition time attendance machine adopts today’s high-precision technology in the international scientific and technological field-face recognition technology (combined with the principles of computer image processing and biostatistics), and uses computer image processing technology to extract facial feature points from the video. The principle of biostatistics analyzes and builds facial feature templates. When a registered person passes by the face recognition machine, it will have a voice prompt “Hello” or the person’s name to indicate that the attendance has been successful. Moreover, it also has an image update function. If the image being taken is the first face, the second face will be stored. If the first face image is consistent with the second face image, the face recognition attendance machine The first face image will be automatically saved to update the second face image. This method can keep the user’s facial image updated, reduce the impact of facial shape changes on recognition, and increase the accuracy of recognition.
Features of face recognition attendance machine
1. The method of positioning key areas of the human face has high accuracy and good safety.
2. Generally, a dedicated dual camera is used, which is a quasi-three-dimensional face recognition technology. The recognition performance is much higher than that of two-dimensional face recognition, and the algorithm complexity is much lower than that of three-dimensional face recognition.
3. The recognition performance is not affected by the ambient light, and the reliability is good.
4. Upload user name list, download access control attendance records and photos via U disk.
5. The device status can be set through the TCP/IP network, as well as upload and download information; network communication data is encrypted.
6. Naturalness, the recognition method is the same as the biological characteristics used by humans for individual recognition.
7. Completely non-contact, can avoid bacterial infection, more health and sanitation.
8. Voice prompt, a real person utters a voice to prompt whether the face image is successfully verified.
9. It can be used independently, without connecting to a computer, it can complete functions such as personnel registration, face attendance, and storage of records.
Face recognition attendance machine working process
Face recognition time attendance machine is mainly used for the attendance statistics of company employees. When employees sign in, they need to collect employee facial photos through the camera, and then use the face recognition algorithm to obtain feature values from the collected photos and store them in the database in advance. The feature values of the employee’s face photos are analyzed and compared, and the employee’s name is reported after the recognition is successful, and the attendance is successful.
Performance comparison between face recognition attendance machine and fingerprint attendance machine
Face recognition time attendance machine combines radio frequency and optical sensor technology with digital camera technology. While punching in with fingerprint or proximity card, it automatically captures the employee’s image information and records it. The background management software can check and compare each Personnel images recorded by pen clocking in, thus effectively eliminating the phenomenon of clocking in for attendance. It is precisely because of this feature that the face recognition time attendance machine not only has the anti-passing punch-in feature of the fingerprint time attendance machine, but also has the advantages of the induction time attendance machine. Face recognition time attendance machine has the following advantages compared with fingerprint time attendance machine:
Because the fingerprint attendance machine has high requirements on the environment and the skin of attendance personnel, it cannot be recognized when the air is dry, the skin is dirty, or the skin is moulted, and the reading head is easy to wear. These reasons make the time attendance machine short life and high maintenance cost. The face recognition time attendance machine is to recognize the avatar information of a person, and it is not affected by environmental and personnel factors during recognition.
The fingerprint time attendance machine needs to be stored in the employee’s fingerprint information database in advance before attendance can be performed. When the staff changes, the fingerprint information database must be updated frequently. The operation is very troublesome, the face recognition attendance machine does not need to input any information, it is installed and used. The face recognition time attendance machine adopts a “U disk” to collect data from the face recognition time attendance machine, so as to avoid wiring. Since it is recognized by radio frequency induction and does not require real-time comparison, the attendance speed is much higher.
Since the fingerprint attendance machine needs to be stored in the employee’s fingerprint information database in advance, and the fingerprint information involves personal privacy, the enterprise has no right to forcibly enter the employee’s fingerprint information. The face recognition time attendance machine has a built-in camera that can take photos and archives of the card reader while swiping the card, so that the card reader can’t hide. Fast speed, swiping card + taking photos within 1 second. Adopt super large capacity memory. Instantly shoot and save. No personal privacy is involved.
The face recognition attendance machine adopts built-in camera and chip to make its performance more excellent. Although the price is higher than that of fingerprint attendance machines, its performance cannot be ignored.
How to use face recognition attendance machine
1. “MENU”-“Administrator verification, enter the system-“Registered user -” input “work number” and press OK-“Face image acquisition, after finishing press OK to save. If it is the first time to use the device and the administrator has not set it, press MENU to directly enter the configuration administrator module.
2. Device connection: After installing the software, click “Device Management”-“Add”-“Enter “Device Number”, “Name”, “Device Type”, “IP Address”-“Press “Confirm”. Then click “Employee Management”-“Import”-“Import from Device”-“Query All Staff Information in Device” to receive the employee information from the device-“Save All”.
Precautions for using face recognition attendance machine
1. Your portrait must be within the scope of the mirror frame; when sampling, as long as the face is within the scope of the mirror, the line of sight is parallel to the center of the mirror or the head is lowered.
2. Please keep your face facing the mirror at a distance of about 30-80cm from the attendance machine, stare at the center of the mirror, move your face back and forth slowly, and maintain a natural look when sampling.
3. When sampling, try to keep the sampling environment consistent with the attendance environment. It is recommended to take samples at the place where the attendance machine is placed.
4. Please keep your expression natural, avoid closing your eyes, squinting, and covering your eyes with your hair. Please do not wear glasses when taking samples and attendance. This will facilitate faster attendance attendance.
5. Do not use near windows exposed to sunlight.
