I think it is less than a car, which you are moving and maybe even causing the usage of more petrol. And the car, you are driving it with intention.
1) Except for a motion run camera, every camera records everything that is in front of it. Every detail is printed as a different pixel – a PERSON is nothing more than a wall.
2) Even if it is considered Kesivah, you are not doing it – at most it is a garmi (direct consequence of your action), and according to the rishonim who say it has to be Beyad (the masser of issur/forbidden action must be done with your actions), here the computer is doing the action, so it a gromo (indirect consequence).
3) It is Lo Nischaven, maybe even Misasek (unintentional), and if you are just walking past, it is Psik Reisha dLo Nicha Leih (a consequence that you don’t want/need).
4) Even a camera run by motion sensor which only records when there is a movement, it is the same as a light-on-sensor outside houses, and the psak from R’ Shmuel Halevi Vosner Shlit”a is that there is no problem to walk past, providing you don’t want the light specifically.
5) It is practically impossible to walk down a main street without being photographed – apparently a walk from Golders Green Station to the North Circular (LONDON) – (twenty minute walk) – you get photographed 300 times. Every shop has one or more security camera, some houses have and the banks have multiple cameras. How do you walk on Shabbos if you dont go in front of cameras?
