Audio recording

In our CCTV world, there are two types of cameras used for surveillance. There is the IP CCTV and the analog CCTV and both can record audio pretty well. The cameras used in a system determine the manner in which sound will be recorded and later replayed.


In an IP system, there is an audio input in the IP camera. The audio input is thus fed straight into the camera. In this system, video transmission between the microphone and the camera is analog. Digitalization of the transmission happens only when the audio hits the camera level. After digitization, the camera would then send a digital signal transmission for playback to the NVR. The IP CCTV system can accommodate several microphones depending on the number of cameras in the system. If the system has five channels, the system will, therefore, accommodate five cameras if there is need.
