If a recent model Pi Camera faces the sky for months or years, is there anything known about damage to the sensor from long term exposure sunlight?
Of course I know this might not be advised, but I'm asking about knowledge, experience or data for this camera, either with the standard lens, or a fisheye.
Assume the standard color camera (e.g. camera module V2) is viewing through some glass or plastic window for environmental protection. Since exposures can be long (no fast movement needs to be recorded) I can add a neutral density filter to cut down on the intensity, but I'd like to know if there is any existing information on this so I don't have to burn up a bunch of cameras first.
Consider the application of a dispersed group of sky cameras for tracking meteors as a way to estimate where the meteorite or fragments may have landed by analizing images from several locations. The cameras may be left facing skyward to operate autonomously for extended periods of time in weatherproof housings such as shown in Instructables.
