Yes, they are 12 volt devices and run from a wall wart. I considered
taking one apart and perhaps adding a heat sink and fan if possible
but have not looked inside one yet. That would probably require
mutilating the case to some degree. But so far, since opening two
windows for cross ventilation things have been working. However we
have not yet reached the hottest part of our summer here although we
have had some near 90°F days.
The building is air conditioned with a few window units. A shop for
rebuilding pianos. I might be able to rig a fan with some simple
flexible duct drawing air from below to cool the camera ...
