Long distance transmission 
The maximum control distance is consistent with that of the UAV, which can reach 7 to 10 kilometres.

Loud and clear 
The maximum volume exceeds 130dB, the effective broadcast range is 300 meters to 500 meters, and the full broadcast range is more than 1000 meters.

Multiple play modes 
The loudspeaker has a variety of broadcast modes, such as text-to-speech (custom timbre) scanning Qr code to transmit text, voice broadcast and audio file playback.
The automatic synchronous pitching function can follow the camera to ensure the accurate direction to achieve the best broadcast effect.

Application
Forest search and rescue
The loudspeaker raises the sound over a very long distance to guide lost people through the forest to open areas, and can quickly locate targets with
other equipment such as an RGM camera/thermal camera, like the E20TVx 

Traffic police to guide
When there is a traffic jam, our loudspeaker can help traffic police to achieve long-distance traffic command and rapid communication.

Other aspects
It can be used to deal with mass incidents, natural resources protection, environmental protection, urban management, maritime law enforcement, etc.
