The analogue noise-cancelling CCTV microphone
Most Turbo HD cameras have no audio capability at all, and the ones that do typically have basic built-in microphones with limited range and pickup quality. The CX-2301A is a dedicated analogue noise-cancelling microphone designed to add proper audio capture to any Turbo HD CCTV installation. Active noise reduction filters out the ambient hum (air conditioners, traffic, mechanical noise) that swamps standard CCTV audio, leaving clean speech and meaningful ambient sound.
Useful at shopfront tills (capturing customer interactions), reception areas (capturing visitor conversations), and any indoor or sheltered position where audio adds genuine value to the video record.
What this microphone is actually good at
- Noise-cancelling audio capture with active filtering of ambient hum.
- Wide pickup range for covering customer-area audio.
- Standard analogue audio output wired into the audio input on a Turbo HD DVR.
- Compact form factor for discreet ceiling, wall or counter mounting.
- 12V DC powered from the standard Turbo HD power infrastructure.
Where this microphone belongs
- Shopfront tills capturing point-of-sale customer interactions
- Reception desks and front offices recording visitor conversations
- Hospitality venue counter areas with combined audio-video coverage
- Body corporate communal areas where audio adds context to video records
Important legal context
Recording audio in South Africa is legal under the RICA framework, but with specific restrictions: at minimum, signage must inform anyone in the area that audio is being recorded. Installations of audio-recording CCTV need to be planned with the legal context in mind. We can advise on the signage and configuration requirements as part of the installation.
