In case you shoot someone in self defense, you don't want a he said, she said situation. You want there to be a color video with audio recording. Even better, let them make an official deposition first before you reveal that you have a video recording. That way, the video will contradict their lies and discredit ALL their testimony as lies. It will taint any future testimony on their part and then it will be a he said they lied situation.
It also comes in handy when the cops give you a false ticket. The video clearly shows that my car has stopped but he gave me a ticket for running a stop sign. It nailed the policeman and my ticket was dropped.
Or lying co-worker accusing you falsely of sexual harassment even though SHE was the one really doing the harassing. Video nailed her and she was fired. Normally, nobody would believe a middle aged man if some young attractive girl accuses him of sexual harassment. However, thanks to my video SHE was fired and I was cleared.
Or the crazy lady that crashed into my car and then admitted that she crashed because she was using her cell phone. I have video of her on the phone. Later, she lies to the insurance company stating that I stopped suddenly causing her to crash and denies the cell phone. The video nailed her and the insurance paid up.
Buy it. It's cheap and it works!
