Ward off pandemic with smart thermal imaging and entrance control

More labor has been put into monitoring body temperatures of those at public entrances as the battle against the COVID-19 pandemic escalates on a global scale. When there’s heavy traffic, people will have to queue up just to be pointed at by a digital thermometer, one at a time. Infrared cameras and devices of the sort have thus emerged on the market as a makeshift alternative, but the equipment is not smart enough and still calls for on-site human force to identify anomalies — in this case, feverish people — and take timely actions. Places with multiple entrances may, from time to time, be swarmed with people, which makes it harder to keep these places airtight, in term exacerbating the risks of the crowd falling prey to the infectious coronavirus.

To tackle the need of a smarter way of public pandemic control, DFI took on the recognition technologies and software platform developed by ioNetworks, and rolled out the centralized smart thermal control system. The system integrates the crucial elements into the platform — body temperature, facial recognition, and entrance control — and frees the whole process of labor intensive duties.

The centralized smart thermal control system eliminates the current over-dependence on human labor in rerouting the traffic flow, guarding entrances, and screening the feverish. The system combines the thermal and IP cameras into one to synchronize both infrared and RGB footages. That way, snapshots of the feverish can be instantly marked with temperature readings and stored in the database by the system, which in the meantime also alerts the staff to take actions. It means that no one has to be placed in front of the monitor to manually identify anyone with high body temperatures, and no one will have to tediously fast forward through the CCTV footage to track down a possible breach.

In major transportation facilities such as airports and stations where there are multiple entrances, the high-end model will work wonders. Multiple areas can be configured on the camera to simultaneously track multiple entrances that fit into the frame — each area is marked with its own temperature reading and is stored separately. When an anomaly is detected, the RGB snapshot and the area of the camera encircling the entrance will be instantly captured, and the system will issue it as an event, and then alerts the staff which entrance is encountering a breach. There will be no more debating back and forth trying to figure out which passer-by corresponds to the thermal warm spot, saving tremendous time and effort in exchange for higher efficiency and accuracy.

In places such as private premises and schools where entrances are rather straightforward, a standard low-cost model can be opted to work with the system and leave the digital thermometers and the guards alone. With no more manual temperature taking while keeping the traffic smooth at the entrance, the impact of the pandemic control on everyday life is kept to a minimum.

The very feature that makes it a turn-key solution is this: the existing access control can take part in the screening process and make the solution truly smart. The system based on the integration between hardware and software  can tell the access control system to initiate a lockdown of an electronic entrance, deny the access, and block the feverish outside. The staff can then sit back in the control center and avoid human contact or the risk of getting infected.

The smart system does not solely assist the pandemic control as a short-term goal, but it aims to pave the way to a smart city in the long run.
