Although I am not planning on doing this, I was wondering what parts of a camera could possibly wear out over time if it were to be used as a webcam all day. For convenience, perhaps it would be kept on perpetually. This would entail the camera being set on "video mode" and kept like that.
I presume that there would be no effect on the shutter life of the camera as the shutter would have to be flipped up once to activate the Live View mode. I am also assuming that the camera is powered using a dummy battery, so that battery wear is negligible.
Are there any points of failure in the camera with such a setup? One issue I could think of is that it may wear out the autofocus motors in the lens, which are likely not designed to be used for continuous use for many days. Are there any other potential points of failure that would come quickly with this setup?
