To me the big issue is that this is about surveillance without a warrant. Not that they're DOING surveillance, but that they're doing it without a check&balance...As far as I understand it (from my time as an intern who worked with the feds) its the premiss of reasonable expectation of privacy. you have a reasonable expectation of privacy in your home, bathroom, car, maybe your backyard if you install a privacy fence. However your front yard is very typically openly visible to any one on the street, Officers and Agents do not have to have a warrants to sit in their cars and do surveillance on you and thats how the cameras came to be. Its much easier for cover to be blown sitting there than watching a secure online database of cameras.
These cams go up on light/power poles.... put up by "power co" or "phone co" reps. They target areas visible from the street. This is not trespass because of the proximity of MOST power poles to the public right of way (the road and sidewalks.) It's not a violation of civil rights because you have no reasonable expectation of privacy in the areas targeted... Think of it like this... if your on the sidewalk in NY, or downtown Charlotte these days, do expect to have any privacy? Probably not. Same goes for any street or sidewalk in the nation even if its your residential street.
One thing a lot of people fail to remember is that the vast majority of agents and officers are JUST LIKE US! They are not out to get you because you shoot, or collect guns, or drink on the weekends. These cameras cost THOUSANDS of dollars to use a week (secure wireless data transfers, secure websites, secure internet services, etc.) They are watching people we all want off the streets... Career Thieves, Possible Kidnappers, Drug traffickers/Manufacturers/Distributers, High Level Gang Members...
Sometimes I wonder why there are sooooo many skeptics in the gun community and I am sure that people who are on the outside looking in at all this stuff wonder why so many of us feel the need to be threatened by Law Enforcement.
