Anyone using cameras or other setups to scan for fever for people walking into your office?

Not scanning with IR cameras. We deployed an employee app to check for COVID symptoms and gave all employees a thermometer.

We still have not returned to offices
Factories are not using cameras

We are headquartered in France. Since almost 6 months every large building is equipped with a camera and PC to do temperature check as people walk into the building. Exactly like you see in airports.
The scanners read temperature and a monitor shows the RED, AMBER, GREEN for temperature in certain range. Works fairly well except when the person walks over in hot temperatures. They may have to wait a few minutes to let the body temperature cool down before entering the building.

I work for a non-profit in DC. All employee badges have been turned off to prevent staff from entering the building without prior approval. A request process has been setup thru our ERP system for staff to both request building access and to agree to the conditions for building access. The conditions include: a mandatory temperature scan; an acknowledgement that PPE is required and acknowledgement that social distancing is mandatory. However, there is an outstanding question around what to do if an employee has received the COVID vaccine. The organization has no plans to require staff to get vaccinated. But vaccinated staff do not pose a risk, so the organization is struggling in how to handle the situation when some staff may have received the vaccine.
