After Police departments in Boston and Los Angeles, Hong Kong is now testing drones outfitted with thermal cameras to fight terrorism, catch bad guys and help with search and rescue operations. The Hong Kong’s elite police squads have recently begun testing with thermal drones. The drones manufactured by DJI, the world’s largest manufacturer of unmanned aircraft vehicles, that recently had its products banned by the US army, were being considered for anti-crime and antiterrorism operations, police officials told the Post. The drones would not be used for surveillance at protests and rallies.
