Does CCTV camera record audio?
In short, the answer is yes, CCTV camera systems are designed to record audio in conjunction with images. However, whether or not an employer or a retail location is allowed to record audio is another matter entirely.
How do I know if my CCTV camera has sound?
If you want to tell if a security camera has audio, one of the easiest ways about it is to look around it. Though usually small, the microphone in a camera is generally very easy to spot. It should be around the camera's housing and is most likely a small black dot that is used for picking up sounds.
