Solution Overview
The Dahua Human Body Temperature Monitoring solution offers the latest hybrid thermal network camera that combines a Vanadium Oxide (VOx) sensor with a 2 MP visible-light sensor. The solution also provides a blackbody calibration device that maintains a constant temperature as a reference point for the thermal camera. The thermal camera coupled with the blackbody calibration device and a feature-rich 4 TB Network Video Recorder delivers a contactless solution for continuous, contactless, and non-invasive temperature monitoring.

Human Body Temperature Measuring technology assists in preventing the spread of viral diseases by allowing for quick, accurate detection of elevated body temperatures. Thermal imaging equipment can easily be installed and implemented to detect elevated body temperature in environments such as airports, hospitals, clinics, office buildings, cruise ships, and any large public gathering location.

Thermal Camera Functions

Uncooled Vanadium Oxide (VOx) Technology
Dahua thermal cameras use an uncooled Vanadium Oxide (VOx) sensor that delivers higher thermal sensitivity in a more compact and cost-effective package. Vanadium Oxide cameras are also more reliable, as compared to other thermal imaging technologies, due to less moving parts.

High Thermal Sensitivity
The VOx detector offers high thermal sensitivity (? 50 mK) that allows Dahua thermal cameras to distinguish objects in a scene with minimal temperature differences. The camera captures detailed images where thermal contrast between object and background is minimal.

Smart Alarm
The camera is equipped with a white-light illuminator and an external speaker that can be triggered when the camera detects an abnormal event either via the thermal or the visible-light sensor. The camera also takes a snapshot of the scene and can record the snapshot.

NVR Functions
The Dahua DHI-NVR5216-16P-I combines Analytics+ algorithms with Dahua's ePoE technology into an all-in-one network video recorder. This NVR uses a powerful multi-core processor to provide 4K resolution processing for applications where impeccable image details are required. In addition, the NVR can be employed as edge storage, central storage, or backup storage with an intuitive shortcut operation menu for remote management and control.

The Dahua Analytics+ algorithms significantly improve accuracy and reliability, as compared to standard intelligent features, to achieve precision human facial analysis. The NVR processes 24 facial images per second on up to four (4) channels of video stream face recognition and supports 20 face databases that can store up to 100,000 total face images. The Analytics+ facial recognition extracts facial metadata, including detecting a human wearing a mask. The system can identify certain facial attributes, including when a human wears a surgical-type face mask. Wearing of such a mask still allows for temperature measurement without interference.

Real-time Face Recognition
Analytics+ performs real-time facial recognition on up to four (4) streaming video channels simultaneously. The server captures and analyzes facial features to determine gender, age, expression, glasses, moustache, and mask, and then can record the faces and store the associated structured data. The server also filters incoming video to display faces that match target features.
