A remote control flying device, called Hawkeye carries a camera to monitor activity in the forest. Images are sent wireless to the forest guard station. Solar panels on the wings power the device and a sound suppressor prevents it from getting noticed. Layers of armored plates in the body panels make the Hawkeye bulletproof as it can be the target of illegal loggers.
