Facial recognition, a biometric recognition technology based on the facial features of human, is a typical application of artificial intelligence. Facial recognition has been applied to some industries, such as the public security field (border inspections and criminal investigations), the transportation field (airports, train stations, and bus stops), and the education industry (facial attendance, dormitory access control, and kindergarten pick-up). It has great prospect as a portal for connecting people and intelligence.

The infrared non-contact temperature measuring technology is widely used in the field of medical temperature measurement. It can accurately measure the body temperature without direct contact between people, greatly reducing the probability of cross infection of viruses and bacteria.

The Kepler FX6 facial recognition device is equipped with a new built-in infrared non-contact temperature measuring module based on facial recognition. During facial recognition, the device can simultaneously measure the temperature of the person’s forehead and facial skin in a non-contact, accurate, reliable, efficient, and unaware manner. For those whose body temperature exceeds a certain threshold, the device will generate an abnormal warning and display their temperature. The unique waterproof and dustproof design of the device meets the IP65 protection requirements, effectively guaranteeing the service life of the device in most environments. Therefore, the device can be widely used in complex indoor and outdoor scenarios.

The Kepler FX6 facial recognition device addresses the high labor costs and low measurement efficiency of traditional body temperature detection devices, and reduces the contact between people and terminals and between people during detection, enabling the rapid screening of crowds.

Features

Effective bioassay with a dual-lens camera

The dual-lens camera can effectively distinguish between living body and pictures, avoiding deception.

Simultaneous detection of body temperature, focusing on personal health

The built-in infrared body temperature detection module achieves a recognition accuracy of ±0.4°C. During facial recognition, it also measures the body temperature of personnel and immediately generates an alarm when the body temperature is abnormal.

Ultrafast and large-capacity deep learning algorithm, accommodating various scenarios

Tens of millions of facial images can be analyzed based on the latest MxNet deep learning framework and aggregate algorithm, achieving world-leading facial recognition. A local facial database containing up to 5000 facial images is provided, achieving high recognition accuracy (> 99.8%).

Service continuity in offline recognition mode

The offline mode of the device ensures continuity of the facial recognition and access control services upon a sudden network disconnection, without being restricted by the network.

Presumable data transfer and offline retransmission, ensuring secure data transmission

Multiple mechanisms such as presumable data transfer and offline retransmission are enabled for device logs, ensuring the integrity and security of data upon network failure.

Application Scenarios

The device provides superb front-end intelligent processing capabilities and is widely applicable to residential estates, communities and streets, governmental organizations, transportation junctions, airports and stations, and schools. In addition to facial recognition, it also measures the body temperature of personnel. The device collaborates with back-end and cloud business platforms to provide customers with solutions such as personnel access permission management, personnel health status detection, visitor management, and attendance management.

FAQs

1. How to measure the temperature accurately? The ambient temperature should not change drastically, the head should be within the portrait frame, and the face should not move violently.
2. Why is the temperature measurement inaccurate after the device is brought indoors from outdoors? After being brought indoors, the device needs to wait for the thermal balance calibration (which takes 20 minutes after power-on as expected) before it can output the normal body temperature.
3. How to measure the temperature efficiently? The device needs to be aligned with the best area of the face.
4. Can the device be installed against the light? The device can be installed against the light, but it is not recommended. Be sure to avoid direct sunlight on the temperature sensor.
