For Integrators Discovery Tool

The Louroe DigiFact E (LE-875) is an ONVIF Profile “T” compatible, wall mounted IP Network 4′′ microphone designed to provide one-way audio monitoring with an omni-directional microphone.

The unit, housed in a vandal and NEMA water resistant enclosure, harnesses the value of networked audio monitoring technology which analyzes and streams bi-directional audio.

Integrating into the Louroe Microphone Application Platform (LMAP), these wide dynamic range audio devices deliver the broad frequency response that users seek, capable of sensitivity in picking up low and-high frequency audibles. Featuring a robust quad-core microprocessor selected to deliver “judicial”quality audio, the LE875 is capable of running an analytical application which detects and processes sounds of a threat including:

  • Pre-set decibel audible alarm
  • Belligerent voice/aggressive voice signals
  • Breaking glass
  • Car/panic alarms
  • Gunshots/explosions
  • Other user specific sounds
