Product Description
This module adds audio to a CCTV system that currently only records picture. It works by pairing a sensitive electret microphone with a built-in amplifier, then sending the signal out as a standard analogue RCA audio feed.
Will it work with your recorder?
Only if your DVR or NVR has a dedicated RCA audio input channel — many budget analogue recorders don't. Check your recorder's rear panel or manual for an audio-in socket before buying; without one, this module has nothing to plug into.
Power and placement
- Runs on 12V DC via a 2.1mm jack, the same connector standard used by most CCTV camera power supplies, so it can often share an existing supply.
- Small enough to fit inside a junction box, camera housing, or equipment cabinet — no need for a separate visible unit.
- Rated for indoor use or sheltered outdoor spots (under eaves, in a canopy) rather than fully exposed locations.
Where it's used
Entrances, till points, offices and warehouse floors — anywhere you want ambient sound logged alongside the video. Because the amplifier boosts sensitivity, it picks up sound across a wider area than a basic passive mic would.
One practical note: mount it away from fans, air conditioning units or anything that vibrates, as that noise gets amplified along with everything else.

Frequently Asked Questions
Will this work with any CCTV recorder?
Only if the DVR or NVR has a dedicated RCA audio input channel — it's designed for recorders that support external audio, not standard video-only inputs.
Can I power it from my existing camera power supply?
Yes, provided that supply outputs 12V DC and terminates in a 2.1mm DC jack, which is the same standard used by most CCTV camera power adapters.
Can I fit this outdoors?
It's suitable for indoor use or sheltered outdoor spots such as under eaves — it isn't described as suitable for fully exposed outdoor locations.
Where should I mount the microphone for best results?
Away from strong airflow or vibration sources such as fans or air conditioning units, as these can affect audio recording quality.
