Voice intercom in the surveillance industry refers to voice communication between surveillance equipment and computers, mobile apps, and platform software. For example, when previewing the monitoring screen on a mobile phone, you can synchronize voice conversations with the characters on the screen. At present, the voice intercom function has been widely used in our daily monitoring environment. It should be noted that it is not possible to talk between devices, such as video recorders and cameras, and between cameras and cameras.
We know that to implement intercom, the device must first support audio input and output, so when selecting a device, you must choose a device that supports audio. The sound on the device side needs to be collected by a pickup and then transmitted to the computer or mobile phone. When the sound from the computer and mobile phone is transmitted to the device side, the sound of the device side is needed to realize the sound output. Therefore, pickups and speakers are essential for the intercom function.
At present, among the full-line products of TSINGSEE Green Rhino Video, the GB28181 protocol national standard platform EasyGBS supports the voice intercom function. This application scenario is suitable for outdoor operations. The voice interaction between the control center and the device can perform real-time operation safety and accuracy. Take control.
The specific operation process is as follows:
1) Visit the camera on the web page, select "Configuration-Audio and Video-Video Parameters", and change the video type to "Composite Stream" (the same applies to the recorder web page access to "Composite Stream")
2) The camera actively registers to the streaming media platform EasyGBS through the GB28181 protocol of the national standard (the camera supports audio, select composite streaming), and at the same time "turn on the audio" function on the server.
3) In this way, the client can collect audio and video data and send it to the device for playback by the camera. The audio pickup system of the camera collects the audio around the device and transmits it to the client synchronously, realizing two-way voice interaction.
Regarding the implementation and usage scenarios of voice intercom, we have listed several cases in the article " How EasyGBS Realizes the Voice Intercom Function ". Users who are interested or in need can read this article. Voice intercom is still in need of continuous improvement in the current environment of the security surveillance industry. Therefore, as a leading manufacturer in the security surveillance industry, TSINGSEE will continue to develop new directions and propose new research topics to further achieve comprehensive Pave the way for the future of voice.
