The Louroe Electronics LE-771 Verifact B-ML Microphone is an omni-directional, low impedance device with microphone level audio quality. This electret condenser microphone is housed inside a high impact ABS dome designed for ceiling or wall mounting. The microphone element is suspended from the pre-amp and dome housing by a 3’ (0.91m) extension cable and is designed for high ceiling applications. The normal pick-up pattern is approximately 15’ (4.5m) from the microphone location in all directions or within a 30' (9.1m) diameter circle. This unit comes with a 20’ (6.1m) pre-made cable with a stereo plug on one end that can be directly plugged to the audio input of an IP camera.
