UPDATE: The Hamilton County Sheriff's Office showed off their new Unmanned Aircraft Systems (UAS) Monday to the media.

The small four-rotor helicopters carry cameras that can transmit video and stills to the drone's operator, and help with search and rescue operations and the documentation of crime scenes.

Other uses for the drones include SWAT standoffs and bomb missions, where officers can avoid being placed in dangerous situations.

The aircraft, called Unmanned Aircraft Systems (UAS), will be used for life-saving efforts, such as locating missing persons and monitoring hazardous conditions. 

Agencies around the country are using drones to extend their ability to perform search & rescue operations as well as document crime scenes.

“This new aerial technology will allow the HCSO to better serve our community in times of emergency and will help ensure that our local law enforcement and emergency personnel are better protected when entering situations that may be dangerous or life threatening,” Sheriff Jim Hammond said.

The HCSO began the process for FAA qualification in December of 2014. Since then, hundreds of hours of training and flight time (over 160 training missions) have been spent to obtain an FAA Certificate of Waiver (COA), according to a news release.
