> Most places where there are surveillance cameras are places where there are also people

I assume you're concerned about reflections from the camera lens or housing? In my mind, the archetypal camera is mounted on a nice tall pole, silhouetted against open sky, and painted matte black.

Surely those would be excessive for someone attacking the sensor, unless they want to remotely sear some graffiti by burning away paint.

Hitting the lens at an oblique angle won’t fry the sensor though? You have to get close to the cone of visibility which is then within the bloom area.
