“DARPA recently revealed information on its ARGUS-IS (Autonomous Real-Time Ground Ubiquitous Surveillance Imaging System), a surveillance camera that uses hundreds of smartphone image sensors to record a 1.8 gigapixel image. Designed for use in an unmanned drone (probably an MQ-1 Predator), from an altitude of 20,000 ft (6,100 m) ARGUS can keep a real-time video eye on an area 4.5 miles (7.2 km) across down to a resolution of about six inches (15 cm).”

“The Norwegian-designed Black Hornet Nano features a tiny camera and relays video and still images to a handheld control terminal.
It measures about 10cm by 2.5cm (4in by 1in) and weighs 16g (0.6oz).
The MoD, which also operates more than 300 larger-sized unmanned air vehicles in Afghanistan, said the Black Hornet is carried easily on patrol and works in harsh environments and windy conditions.
They have been in use in Afghanistan since 2012, a spokeswoman confirmed.”
