Audio Pickup for CCTV Surveillance
This microphone captures audio for CCTV video surveillance and IP camera systems. It connects directly to DVRs or audio matrices for synchronised audio-visual recording. The unit is designed for security installations that require sound monitoring alongside video footage. It suits installers adding audio capability to existing camera infrastructure.
Upgrades Silent Video-Only Systems
The device replaces setups that record video without any audio track. The jump is worthwhile when investigations or monitoring demand clear voice capture, such as entrance lobbies or interview rooms. It adds a high-fidelity audio channel without replacing the cameras themselves. Buyers who only need motion-triggered video recording gain no benefit from this addition.
Sustained Operation With Noise Control
A digital processing chip continuously filters background noise and high-frequency interference during long recording sessions. An electrical noise dynamic closed-loop circuit actively restrains hum, while echo-reentrant suppression reduces reverberation in empty rooms. Built-in automatic gain control keeps levels consistent across varying distances. The microphone maintains low power dissipation and stable performance over extended transmission distances.

Questions about this item
What connectors does the pickup microphone require to fit inside a CCTV camera housing?
The unit uses a top-mount audio head with a built-in processing chip and connects directly to a DVR audio input or audio matrix via standard audio wiring.
How is the microphone installed, and which step is often missed?
Mount the audio head on top of the camera, run the cable to the DVR or recorder audio input, then adjust the sensitivity on the processor — skipping the sensitivity adjustment is the common mistake.
What maintenance or replacement will the microphone need over time?
The microphone has no moving parts or user-serviceable components; if the processing chip or cable fails the entire unit is replaced.
