A story about pipe sewer camera audio function

How do you think of take audio function? It is convenient for our work. 

Also it will make some funny things. 

Last time when we visited a customer. He told us a story. 

One time when worker using the camera, he forgot to turn off the audio. 

But he said something is secret. The voices be recorded into the video. 

And his boss heard the secret… It was a little awkward. 

Warm notice when said something personal, please don’t forget to turn off the audio function.
