Some passengers traveling through Denver International Airport this holiday season are in for a treat--or what amounts to a treat in today's high-throughput, high-stress security environment. As they go through TSA screening, they'll be able to keep their hands at their sides because of a new type of rapid body scanner. Instead of standing sideways in a plastic tube while a scanner shwoop shwoops around them, Denver fliers will step between two white plastic walls, about 4 feet apart. There are no moving parts, and the scan takes less than a second; if all is clear, the passenger moves on. The Denver scanner is built by Rohde & Schwarz, which also has a system up and running in Cologne Bonn Airport, Germany.

The global videos surveillance market is expected to post a compound annual growth rate of close to 11% during the period 2018-2022 according to Technavio. The potential benefits of leveraging artificial intelligence (A) in the physical security industry have pros and cons on both sides, but the debate over the ethical ways to leverage AI and surveillance continues as more and more surveillance systems are getting the brains to match what they see. AI startups like Boulder AI, which offers a vision-as-a-service and IC Realtime, which lets you search and analyze your video feeds from CCTV system; are gaining traction. Alongside the Chinese facial recognition startups like Megvii's Face with $600 million in private equity; SenseTime with $62o million from a series C; and, Yitu Technology with $300 million from a series C, the potential uses of facial recognition technology are well funded.
