External Microphone

The Microphone Unit is not adjustable.

This unobtrusive product, when connected to a DVR or audio verification control panel, makes an ideal addition to your security installation.

The “Gain” of each unit has been factory set.

It is therefore important that the location of each unit to be installed is carefully considered such that it provides the optimum performance.
