This patent, US 6831556 B1, basically says that these guys are entitled to be the only company who can package off-the-shelf video and audio recording devices with cameras in a police car and market it as such. That is ludicrous and it makes me wonder how a patent is acquired for such non-sense.
I am not a competitor but a consumer and received a letter from this company (patent holder) who essentially markets their system by threatening consumers with patent infringement if they buy a competitors product instead of theirs. When I looked to verify the patent, I was confused and amazed that such a patent could even be acquired.
They sent a nice but passive aggressive cover letter with their catalog saying that they heard we may be in the market for such systems and, oh, by the way, you may want to consider buying from us because we will sue the heck out of you if you buy from someone else. Effectively saying, "We are the only people who can legally pair a camera, microphone, and digital recorder together as a system inside a cop car."
And, the company doesn't even manufacture any of those products, AND, they are not the first people to have done it. This thing came about after the year 2000. I know cops who were putting cameras in cop cars in the 80's.
