What is a Pan/Tilt Long Range Acoustic Hailing Device ?
Pan-Tilt Long Range Acoustic Hailing Devices send sound with directivity and high power unlike general loudspeakers, so are able to transmit highly clear and intelligible sound to a long distance. Therefore, it is suitable for announcement, warning broadcast, etc. It also has a pan tilt (drive unit), so it can be operated up, down, left and right.

Main Features of Acoustic Hailing Device
- Since it broadcasts with directivity and high power, it can transmit highly clear sounds to a long distant (1km).
- With maximum output above 142dB, it can get over the noise of the surrounding areas and can provide large and clear communication and warning signals to the inside of vehicles, ships or buildings, overcoming the limitation of the existing broadcasting system (P.A. System).
- It is possible to broadcast using a sound source and a microphone.
