What camera can connect speakers?

For example, Logitech camera, Google camera and Oni camera can be connected with external speakers.

The camera can listen to audio in two ways, one is the built-in pickup; One is an external pickup. The built-in pickup camera usually comes with pickup function when it leaves the factory, and you can listen to audio after installation. Here's how to connect an external microphone.

Generally, an ordinary pickup has three wires, namely, a white or yellow audio signal wire, a red power positive electrode and a black power negative electrode (male * * * ground wire), and the black male * * * ground wire needs to be connected to the 12V power negative electrode and the audio IPC ground port (G).

If it is a pickup with lotus connector, it can be converted through the corresponding adapter and then connected to the audio camera through RVVP shielded cable.

Just connect the camera and the video recorder with a network cable, and there is no need to add another transmission line. You can preview the picture by searching and adding IPC in the normal way.

After the pickup is connected with audio, a camera needs to be configured, and the IP address of the camera can be accessed on the webpage. In the configuration-video parameters, you need to change the video type to "composite stream", and in the audio parameters, the audio input is selected as "Linein" for saving and restarting. At this time, in the preview screen of the video recorder, click the speaker icon to hear the real-time sound and audio of the surveillance camera.
