How to check if a video has been edited? Has the video file been modified? and how can I verify the authenticity of the video file from the webcam? I so understood on checksums? or else how? who knows?

Answer 1

If the installation was done correctly, then no way. You can identify it by the frequency characteristics of audio and video streams at the installation sites, because of the gaps there will be bursts.
But in general, the task is quite difficult.

Answer 2

Checking is very simple - you need to hire an expert to conduct an examination, and put all your questions before the expert. The courts do this.

Answer 3
