Product Description
A high-gain electret microphone module that adds an audio channel to CCTV recording systems. It suits installers adding audio capture to an existing video setup rather than starting from scratch.
What it does
The module houses a sensitive electret microphone with a built-in amplifier, boosting sound pickup beyond a passive mic. Output is via a standard RCA connector, so it connects directly to any DVR or NVR with an RCA audio input channel — check the recorder has one before specifying this module.
Power and fitting
Power comes from 12V DC via a 2.1mm DC jack, the same connector type common to CCTV camera power supplies. That means it can often share power infrastructure already run for a camera on site, rather than needing a separate feed.
The module is compact enough to sit inside a junction box, camera housing, or equipment cabinet, keeping it out of sight rather than mounted as a standalone unit.
Where it fits
It's built for indoor and sheltered outdoor installations — under a canopy, in an enclosure, or similarly protected — not full outdoor exposure. Typical use cases include entrances, retail counters, offices, and warehouses where audio alongside video is wanted. For best results, mount away from strong airflow or vibration.

Frequently Asked Questions
Is a separate power supply required for this microphone?
It runs on 12V DC via a 2.1mm DC jack, the same connector standard as many CCTV camera supplies, so it can share existing power infrastructure.
Is it compatible with any DVR or NVR?
It connects via standard RCA audio output, so the recorder needs an RCA audio input channel to accept it.
Can it be mounted fully outdoors?
It's specified for indoor and sheltered outdoor use, so it needs protection from direct weather rather than open exposure.
Where is it typically installed?
It's compact enough to fit inside a junction box, camera housing, or equipment cabinet at locations like entrances, retail counters, offices, and warehouses.
