From the unattended & remote warfare department is this tool:
"The HUNTIR Round is a fixed-type cartridge designed to be fired from 40mm Grenade Launchers M79 and M203 (attached to the M16/M16A1 rifle) or a Milkor MK-1/[MGL-140] Grenade Launcher. The round consists of a cartridge case assembly, and a metal projectile body containing a first fire charge, a pyrotechnic delay column, an ejection charge, a CMOS Camera, and a parachute assembly. Upon firing, the projectile assembly is propelled to an average height of 700 feet, the first fire charge ignites the pyrotechnic delay element, which ignites an ejection charge that effectively ejects the CMOS Camera, which is attached to the parachute. The CMOS Camera provides up to 5 minutes of real-time streaming video to a handheld device with a correcsponding transmitter."
