Earlier quoted context omitted.
The camera isn't your accuser. The municipality is your accuser, using the evidence from the camera as proof of the law being broken. If you break into a building and get busted by an automated silent alarm, the alarm isn't the one accusing you.
If i get pulled over by a cop and he doesnt show up to court, my ticket is dismissed. When i get mailed a ticket from a corporation, who is expected to show up in court to be my 'accuser'?
Some cursory googling turns up this as pretty common, occasionally it will be a police officer.
