What is our micrphone for?
This audio surveillance microphone can be added to any surveillance system with audio input. The CCTV microphone is typically used as an add-on to CCTV cameras that do not have built-in audio.
This microphone is stand alone as it does not rely on the power source from a security camera. Plug and play cables can be used with these microphones to easily run both the audio and power centrally back to the DVR.
The Mic comes with its own 12V DC power supply and can be used with CCTV Camera Pros stand alone surveillance DVRs or PC based DVRs, such as Geovision.
Because the microphone has a female RCA input and most DVRs have RCA inputs for the microphone inputs, we include two BNC to RCA converters for each end of the plug and play cable. Order the cable with this microphone and the converters are included. See the below audio surveillance connection diagram for more information.
