How to choose the face recognition attendance system?

1. Check whether the Face Recognition Attendance has the function of liveness detection

The liveness detection function, as the name suggests, is the function of judging whether the current person is a living thing. Some people may use photos to deceive the machine. Liveness detection can effectively resist common attacks such as photos, face changes, masks, occlusions, and screen remakes.

Liveness detection is divided into cooperative and non-cooperative. The cooperative mode means that people need to perform specified actions according to the requirements, such as blinking. The non-cooperative type does not need to do any actions.
Generally speaking, if you can use non-cooperative, use the non-cooperative type. After all, it saves trouble and effort, and people are always lazy, but the non-cooperative type has certain requirements for the hardware and algorithms of Face Recognition attendance.
2. See if face recognition attendance can cope with complex scenes
Scenes and people are changeable, and face recognition attendance must be able to consider unexpected situations such as environmental changes and personnel changes.
In order to cope with complex environments, the face recognition technology used must support various complex environments such as strong light, low light, and dark night backlight, and can detect multiple faces such as frontal faces and side faces.
Only in this way can the requirements of Access Control be met, and the efficiency of face recognition attendance can also be improved.
If the face recognition attendance is placed outdoors, then the requirements for this function will be very high. You should not want people to work when the sun is strong, thunder and rain, and there is no light.
Facial recognition attendance is useless.
3. Check whether the face recognition attendance can be upgraded from the old recognition attendance
At present, the identification and attendance Access Control System has been developed for more than 20 years. The identification and attendance access control is almost everywhere in shopping malls, units, communities, and subways. It can be said that the traditional identification and attendance has covered a large area.
It can directly transform and upgrade the face recognition attendance on the original old recognition attendance, which can not only save the expensive cost of replacing the entire recognition attendance, but also save materials and protect the environment
If the old identification Time Attendance cannot be transformed, once the new identification time attendance is settled, the old one will only be thrown away, sold, or scrapped.
4. Check whether the face recognition attendance algorithm is deployed locally
Generally speaking, the face recognition algorithm in face recognition attendance will be deployed on the cloud server or locally.
If it is deployed in the cloud, the hardware configuration requirements for recognition attendance are not high. In order to reduce hardware costs, some face recognition attendance algorithms will be placed on the server. In some cases, face recognition cannot be performed, and data may be lost. It is best to choose to deploy the face recognition algorithm locally on the machine, even if it is offline, it will not affect the use, and it can also protect local data and avoid data loss.
