Very easy trophy.
Just as it says: destroy 15 cameras.
This can be done on multiple playthroughs with the same save, or in the VR missions.
The tanker has 2 cameras you can take out, and depending on the difficulty, the plant can range from 1 to several.
VR missions range all over the place, and depend on the mission type. Eliminate all has a few during the last missions (respective of the character), and if I recall the Bomb Disposal missions have a couple here and there. Replaying a VR mission for the cameras is an option as well, if you want to grind them out.
