From hospitals and schools to banks and retail departments, AXIS T8355 Digital Microphone is ideal for any location where you need distance between the audio source and network product. Audio right where you need it AXIS T8355 Digital Microphone offers a broad range of mounting accessories to help make installation fast and flexible.

This makes the microphone perfect for surveillance situations where the network product is installed in a control room, away from the audio source, such as is often the case with casinos and airport security control. Additionally, AXIS T8355 Digital Microphone is powered by the network product, so no additional cables or power supplies are needed, helping minimize time and installation costs.
