Ubiquitous surveillance would presumably try to have every camera within view of at least one other camera, so sabotaging them is a good way to get tracked down and arrested.
You don't have to attack the camera directly to sabotage it. Cutting power or communications cables and jamming transmissions works too.
Believe me, I wish it was that easy.
Jammers are trackable, but if you use them judiciously, I think they could be used to cover other attacks: activate jammer, attack camera infrastructure, deactivate jammer, and flee.
