AA002 is a high-quality CCTV microphone. It can receive sound near an area and transfer it, along with camera video, to a remote DVR for recording via cost-effective audio and power cable. Moreover, the microphone has a decent performance that can effectively receive the sound in small-to-medium-sized spaces to save the audio recordings in a DVR.
