Contactless temperature screening stations deployed in Chinese and Korean universities
Shenzhen University (Shenzhen, Guangdong, China; www.szu.edu.cn) has deployed a temperature checking kiosk developed by smart terminal and solutions provider Telpo (Foshan City, Guangdong, China; www.telpo.com.cn) as part of its pandemic containment measures.
The TPS950T terminal, 188 x 94 x 27 mm in size, runs off the Android 8.1 or Linux O/S. The system includes an 8-core 1.8 GHz processor, 2 GB DDR and 16 GB eMMC memory, and RS485/Weigand and RJ45 connections for connections to access control stations and the internet respectively.
The system, designed to deploy on walls, floor stands, or turnstile mount brackets incorporates an infrared (IR) image sensor developed by Melexis (Ieper, Belgium; www.melexis.com/en), a silicon-machine thermopile with digital outputs, and uses a dual-lens RGB + IR camera to measure forehead temperature within 0.3°C from 50 to 70 cm, according to Telpo. Two white-light LEDs allow the kiosk to function at night or in low-light conditions as well as in daylight.
An alarm triggers if anyone using the kiosk scans at a temperature higher than the normal body temperature threshold set during system activation. QR-code or near field communication card scanning provides identity verification, and the kiosk can also detect whether the user wears a mask. The terminal can also register visitors and provide real-time temperature reports.
To participate in the test, Shenzhen University students must provide health information to obtain a clean bill of health and a green code. The students must have their body temperature scanned three times each day and swipe their student card at the kiosk to confirm their identity, for 14 days.

Chung-Ang University (Dongjak-gu, Seoul, Korea; neweng.cau.ac.kr) installed for testing the UBio-X Pro2 contactless face recognition system from biometric solution provider Union Community Co. Ltd (Songpa-gu, Seoul, Korea; www.virditech.com), on the university campus at the Da Vinci SW Education Center. Test candidates will apply for non-face-to-face visits in advance and then certify their entry to the test location on the same day.
According to the manufacturer, the UBio-X Pro2 can recognize faces at up to 3 m away and measure body temperature with an integrated thermal camera. The device has a 149.7 x 208 x 56.4 mm footprint, runs on the Android 6.0 O/S, features a 1.0 GHz Quad-Core ARM Cortex-A9 and 900 MHz Dual-Core ARM Cortex-A7 CPU, 16 GB eMMC and 8 GB DDR DDR3 memory, and has RS-232/RS-485 and Wiegand interfaces.
