Why do you have a camera and a mobile phone to take people out, and you can still hear people talking outside in the store?

There are two main types of voice intercom for cameras. Class 1 is a home camera with its own microphone. After installing APP software on the mobile phone, voice intercom can be realized. The other is the camera used in the project, which needs to be equipped with a microphone interface, and then choose a microphone device for voice intercom. Let me share it briefly!

1, the camera has its own voice intercom function.

Home cameras have their own cameras. As long as the camera is installed, then download the mobile phone APP of the installation manufacturer, scan the QR code of the camera and bind it, you can realize voice intercom with the camera through the mobile phone APP.

2. Add a pickup truck.

For engineering machines, many cameras have no pickup function, so it is necessary for the camera to support the interface function of the pickup, and then add a pickup.

① The analog camera is equipped with a camera.

Adding a pickup to an analog camera requires the DVR to support the audio port AUDIO IN, which is connected to the pickup, while AUDIO OUT is an audio output port, which can be connected to an external speaker.

② The webcam is equipped with a microphone.

Now the mainstream is network monitoring. Installing a pickup in network monitoring needs to reserve a pickup interface in network monitoring. You can go to the corresponding official website to check whether the camera supports the audio interface. With the audio interface, you can install the pickup.

3. How to set it up

The current monitoring is network monitoring. After the line is connected to the camera and pickup, you need to enter the network hard disk video recorder configuration code stream, log in to the network hard disk video recorder management interface, select configuration, select audio and video, select video stream, change it to composite stream, check record audio, and finally save.

To sum up, for a family camera, it has its own camera function. As long as you install the mobile APP and add the QR code of the mobile phone normally, you can have a two-way voice conversation with the camera. For the project machine, the webcam is required to support the audio interface function, and a pickup is added; Analog cameras need to support audio in the DVR pickup interface.

Praise it.
