Ask a question about the method of monitoring audio connections.

With audio function, it means that the network camera has an audio input interface, which can be connected with a pickup, and the pickup should be purchased separately.

If the front-end is a webcam, the camera supports audio input, and the pickup is connected to the camera audio interface. The back-end video recorder NVR only needs an audio output interface to connect the speaker to play sound.

If the front end is an analog camera, then the pickup is connected to an analog video recorder DVR, and the video recorder supports five channels of audio, so five audio interfaces are enough.
