Every camera company is a bad company.

As someone who worked for a water damage restoration company thru high school, you would be very thankful for a washer that has a leak detection system. I cannot count how many homes we had to dry out from washers and water heaters that started leaking when the family was out of town. I agree with you that some tech is not good but when it comes to stuff like this I am all for it.

 

Unions are in a class by themselves, and each situation is different. Police tend to stop people committing crimes. Truckers are not automatically suspected criminals.
I'm in law enforcement myself, and I have cameras on me. The problem turns out to be that there isn't enough time available to the supervisors to review the footage over petty violations. So it's assumed that the officer is correct—even without any review of the camera footage. But then, I only deal with criminals. The camera footage is almost never used as a gotcha against correction officers. Almost never. I suspect that the reason for that is that if they did this, an already extremely hard-to-fill job would become even harder to fill. In fact, I'm almost sure that's the reason—based on my knowledge of the job and my peers. The union contract doesn't even have a place anywhere in it where it mentions their usage. I know the contract by heart. I would have loved to have reviewed footage this very morning, because of inmates trying to drive me crazy by conspiring to gaslight me on petty issues. But the supervisors tend to just be too busy, and I respect them too much to waste their time.
All this camera stuff winds up coming right down to integrity and good judgment of humans, yet again. I can catch inmates violating literally hundreds of rules per night. It would be impossible to enforce all of that. Some violations are really psychologically threatening in this industry where CO's are stressed to an average life expectancy of 58. Every inmate would be in jail for life if I wrote up every violation. It all comes down to my own tact and leadership abilities. Can I change behaviors? Can I deter bad people from doing bad things? Can I get respected enough to slow down violations? Only I can sort out the few rules that are propitious to enforce from the ones that simply would not result in a good ending, if enforced. And those are typically very serious ones.

I'm the one that runs the camera—no machine does it, and no third-party does the judgement of whether or not it actually happens. But truckers are not convicted criminals. And they ought not be treated as so. Truckers typically don't even have unions pushing back against camera usage either. The presence of a union can push back or even threaten to push back against over-use of technology. This makes a world of difference in your argument. An industry without a union can be divided and conquered. I can see why the police resented cameras at first. They were in an experimental phase, and to be quite honest with you as a person in law-enforcement myself, I can tell you that the system these days is getting scary-biased against us, where criminals seem to be making news almost as heroes these days even while blatantly committing serious crimes.
