Could you elaborate on what you think the benefits are?
I'm of the opinion that systems that indiscriminately check whether all people nearby are currently committing a crime should not be things we should be building in our society. I would prefer there be a reason to suspect a person of a crime, and pursue on a targeted basis, rather than simply have panopticons charging people with crimes.
For example- with the system in this article, I would prefer if a person were required to call in and complain "there was a too-noisy car at this location at this time", and then a person reviewed footage from that location at that time and determined whether to send a ticket out or not.
Regarding your points about transparency, I completely agree with you.
