Fever detection technology added to biometric hardware by Dermalog, Telpo, DFI, Hikvision and Kogniz
A new camera which measures body temperature with high accuracy and speed has been developed by Dermalog for biometric fever screening to increase public safety.
The company notes that the German Robert Koch Institute says almost 90 percent of people infected with COVID-19 in China have been diagnosed with a fever, making fever screening a valuable tool for virus transmission prevention.
The new Dermalog camera can simultaneously check up to five people for fever, and set of an alarm or deny access if a fever is detected, for instance as part of an automated access control system. The camera is also highly accurate at a distance of up to two meters, according to the announcement. The company says its solution is already in use at border control points, airports, trade fairs and events, and could be applied to healthcare facilities such as hospitals and nursing homes, as well as factories, offices, shopping centers, hotels, and schools.
Telpo, Hikvision offerings reviewed
After pushing out a series of updates and additions to its biometric identification technology to likewise leverage fever detection as a means of limiting virus spread, Telpo has provided an overview of the new offerings available.
Contactless sensors from industry leaders like Heimann and Melexis provide fever detection within seconds, blackbody temperature calibration, high temperature warnings, unified data management and multi-scene management with different installation methods and languages supported are among the new devices’ features.
New hardware includes the TPS530 bus validator, the TPS980T is intended for offices, and the TPS450 is designed for supermarket applications, while the TPS350 provides handheld mobile identification and temperature screening.
These include the handheld DS-2TD2TPAN A/VI, which scans people in one second and automatically uploads an image of a person with a fever to a central server, two “bullet” cameras for fixed long-range temperature screening, and Hikvision’s DS-K1T671MF and DS-K1T331(W) facial recognition terminals for multi-biometric checks at scale and wireless operation, respectively.
DFI and Kogniz each integrate temperature checks
Many existing deployments of infrared cameras and devices that have emerged as an alternative to manual temperature-taking with a digital thermometer for access control still require human involvement, such as to take action if a fever is detected, according to DFI. In response, DFI has launched the Centralized Smart Thermal Control System, which is based on recognition technologies and a software platform from ioNetworks.
The system integrates body temperature checks, facial recognition, and access control processes to remove intensive human labor from the process. Footage from IP and thermal cameras are combined to identify people fever is detected in for immediate action.
The system is recommended for applications such as airports and transport stations. Multiple entrances can be tracked by configuring cameras in a network, which logs events and makes clear which individual is the one triggering the alert.
The combined hardware and software, including DFI’s IPC interfaces and stable computing power, can also be integrated with existing access control technologies as a turn-key solution.
While intended to help control the pandemic outbreak, DFI says the product is also meant to enable smart city applications in the longer run.
Kogniz is offering the Kogniz Health Cam for autonomous temperature monitoring of people in high-flow environments. Temperature is checked in real-time as people walk by, and any person found to have a fever has their image captured and their temperature displayed.
By calculating a histogram of temperatures of every person walking by, Kogniz says it is able to provide extremely accurate temperate detection across different office environments. Alerts can be sent through SMS, mobile push or Slack, and live video streams can be access through Kogniz Health, and remotely through the Kogniz mobile app or web interface.
The system also provides exposure identification, and detects temperature up to 16 feet away.
