Product Description
What it is: a small in-line audio module that lets a CCTV system capture sound, not just picture. It takes a microphone signal, boosts it (high-gain) and balances it for the recorder, then sends it out over a standard RCA connector.
Why bother with audio on CCTV
Video alone often misses context — a raised voice, breaking glass, a car door. Adding a microphone module gives your recording a soundtrack to go with the picture, useful for reception desks, tills, gates or anywhere a conversation matters as much as the footage.
Connections and power
- RCA audio output — feeds any DVR/NVR or amplifier input that accepts a line-level RCA source. Check your recorder actually has a free audio-in channel before ordering; not every DVR does.
- 2.1mm DC jack — needs its own power feed. Plan for a nearby socket, or share a PSU with the camera it's mounted alongside.
- Indoor and outdoor rated, so it can sit inside on a reception wall or outside near an external camera run.
Fitting it in
Being compact, it mounts discreetly close to the camera itself or partway along the cable run — wherever is tidiest. It's an in-line device: it doesn't record or store anything itself, it just prepares the microphone's signal so your existing DVR/NVR can capture clean audio alongside the video.
