Here is an autonomous tethered drone system that makes it easier for law enforcement to monitor dangerous situations. Axon and Fotokite collaborated on this public safety system that delivers autonomous flight without needing a pilot. The Fotokite Sigma draws power from power sources on the ground and can fly safely in severe weather conditions such as rain and snow.
The Fotokite Sigma can stay airborne for more than 24 hours. Its video footage is integrated into Axon Evidence to let agencies know what is happening in a given accident. The drone can reach a max altitude of 150ft.
