1. What is face recognition? What is its basic principle?

Face recognition is a biological characteristics recognition technology, using the inherent physiological features of humans for ID recognition. The technology does not need to be carried about and will not be lost, so it is convenient and safe for use. The basic principle of Hanvon face recognition includes:

2.What is F710 and what is its target market?

Face ID is industry first embedded facial recognition system with leading “Dual Sensor” Facial Recognition Algorithm, FAR <0.0001% which makes facial recognition more faster and accurate, different source-light technology enable the system works well under different environment for access control and time attendance

3. What are the advantages of face recognition technology compared to fingerprint technology?

Face recognition is the most natural biological features recognition technology according to the cognitive rule of human beings; its algorism is ten times more complex than a fingerprint algorism. Face recognition is featured by the following advantages compared to fingerprint:

Accurate and Fast Identification:
●Industrial Leading “Dual Sensor™” Facial Recognition Algorithm, match more data than fingerprint, FAR<0.0001%
●1:Many up to 1400 users less than 1 second

High Usability and Security
●Failure to enroll and acquire rate is less than 0.0001%, fingerprint technology will have problems for enrollment with cold, wet, desquamation, elder, around 5% people can not get enrolled with fingerprint technology
●Incident trackable for security with photo which captured by camera, there is no evidence with fingerprint technology to track the incident.

User friendly design:
●Contactless authentication for the ultimate in hygienic

4. In what aspects does the “Dual Sensor® V2.0” face recognition algorism exceed the general single-sensor face recognition algorism?

Hanvon Technology has been dedicated in pattern recognition for over ten years. As the technological and market leader of handwriting recognition and OCR technology of China, Hanvon focused on world-class face recognition technology early as 2003 and actively engaged in R&D of face recognition ever since. Five years of effort finally produced the Dual Sensor”® face recognition algorism with fully independent intellectual property.
Adopting specific dual sensor, it is a semi-3D face recognition technology, recognition ability of which is far superior to 2D face recognition, while the complexity of its algorism is far less than that of the 3D face recognition. It’s a world-class technology with recognition capability dramatically better than the average single-sensor face recognition algorism – in other words, their difference is the same as the difference between a two-eyed man and a single-eyed man.

5. What’s the rejection rate and error rate of the “Dual Sensor® V2.0” face recognition algorism?

FAR <0.0001%,FRR <1%. (Testing database of over 100000 samples)

6. Can the product recognize twins?

Differentiate twins is difficult by face recognition; however, our Dual Sensor ”®V2.0” face recognition algorism can differentiate some twins, the differentiate rate is 80% based on 15 twins templates.

7. Will pictures, head models and waxworks incur error recognition?

No, they won’t. Our product has the unique live face detection function; nonliving objects, such as pictures, head models and waxworks, would not cause recognition error.

8. What if there is recognition difficulty or error for some particular person?

The security performance of key and card is far less than that of biological features recognition. The average error rate of key is only 1 in ten thousand. So if there is a difficulty or error for one person recognition, you can register again or activate the face contrasting function.

9. How many people can the product support in maximum capacity?

It supports 1:N face recognition with capacity up to 1400 users.

10. How many face product templates can one person in the product support?

Up to 18 face templates can be supported by one person to include more postures information and to enhance the face recognition ability.

11. How many records can be stored by the product in maximum capacity? Is there any signal if it’s full?

Up to 200000 face recognition records and 70000 card-reading face contrasting picture records can be stored, enough for two months’ use. When the storage capacity has been consumed 85% or more, the stand-by interface will display clear percentage signals which are upgraded automatically, to remind an administrator to export and clear all records.

12. What’s the capacity of the SD card in the product? How is it used?

The SD card of the product has 2 or 4GB capacity, chiefly used to store 70000 card-reading face contrasting picture records and the security picture (which is stored no matter whether the recognition has succeeded or failed). As a result, the SD card should not be pulled out when in use. The security pictures are replaced by new ones based on time order; in most cases, pictures taken in the last week can be kept, then you can upload and view the pictures through computer management software.

13. Why is the security picture black-and-white?

Considering the many layers of graphics, storage space will be saved if the graphics are compressed. So we make the security picture black-and-white.

14. Why does the product adopt the unique slope structure?

The height range and comfort of users must be considered in face recognition technology. For this reason, Hanvon developed the unique 53° slope structure, which could expand the height range of the product to 50cm as well as ensure a comfortable cervical vertebrae curve angel.
The product is suitable for people between 1.45m and 1.95m. In cases of special usage (such as in kindergarten), the overall height of product installation could be lowered accordingly.

15. In what environment can the product be used? How is its adaptability to ambient light?

The product can be used indoors in surroundings such as offices. It can be used in 0-50000 Lux (unit of luminance) and will not be affected by ambient light.

16.What is the ideal distance for use of the product?

The face should be 30 – 80 cm from the product.

17. What is the dimension of the product?

200* 95* 115 mm.

18. Will the data stored in the product be lost when powered off?

No. The product uses flash memory and a SD card to store data.

19. Does the product support TCP/IP network communication and WAN?

Yes, it supports TCP/IP and WAN (please contact the network administrator for the correct network configuration).

20. Describe the hardware platform of the product, and how fast is face recognition?

Face recognition is featured by tremendous calculation volume, which is ten times more than that of fingerprint recognition. So we adopted the high-speed digital signal processor produced by the American company TI, with basic frequency up to 600M, i.e. 4.8 billion commands can be processed in one second. Through algorism optimization, our product is the first in the industry with the capacity of processing five face recognition frames per second.

21. Users must first register with an administrator to use the new product, why?

Yes. To use the new product, it must first be registered with at least one administrator. This is because of the high security and optimized management system of the product.

22. Can the product read cards? How to grant rights?

Considering the card-reading habits of users, the product support card-reading, and then conducts 1:1 face contrast and saves the small color picture. You can grant the card-reading rights for face contrast during the registration or modification of administrators and users.

23.Does F710 support Wiegand protocol?

F710 supports Wiegand 26 output or Wiegand 34 output. It is standard Wiegand protocol that compatible with most access control panel.

24. Does F710 support encrypted communication door access functions?

Yes, it does. The F710 can be set in encrypted communication mode, which is one-to-one corresponding to the specific controller HC2008 (needs to be purchased separately) to meet higher security requirements.

25. What should be noted in user registration and recognition?

a.Keep head low naturally, and the face parallel to the screen; Distance at 30 centimeter to 80 centimeter between face and screen required;
b.During the enrollment, please show your face in the middle of the screen according to the guide on the screen like turn head to left or right side, or raise and lower head slightly, so that the every part of your facial character will be acquired by the sensor;
c.When the white dashed frame appears, it means your face can’t be detected by the system, please adjust your face expression and position;
d.The green line frame will display if the device detects your face successfully;
e.Below conditions are preferred: indoor use, normal face expression;
f.Below conditions are forbidden: direct sunshine, wear Sunglasses;
g.When you are wearing glass, please take off your glass/specs after the half enrollment process then continue the second half enrollment.
