It was surprising to see, in your news report on 14 January, a quote describing infrared people-counting technology as “outdated”. This is incorrect. On the contrary, many retailers have rejected video-based people-counting in order to adopt infrared thermal technology.

The Irisys thermal imaging-based solution is the most widely used detector for people counting and queue management in the world.

Infrared, thermal sensor solutions offer increased accuracy in people counting, with none of the privacy or security threats that are associated with a video solution. Outdated? No. Out in front.
