Thanks, my initial search found cameras for oil rigs, which minimized sparks :) I've used carriage bolts to reinforce steel enclosures, with single-use wire rope seals for tamper detection on covers, minimizing exposure of the clamping point.

Axis P1204 has a small camera sensor separated from the camera body by a 25' cable, which makes it easier to enclose and secure the camera body. Not seen that elsewhere, must be a proprietary protocol on that cable, e.g. RPi camera sensor cables can only be a few cm.
