I guess the major advantage over the keychain cameras some folks here use is that this can transmit video to a device over WiFi.

I recall seeing one of these in use on YouTube but I can't find the video at the moment. The guy solved the clearance problem by strapping it to a flatbed pushed by a powered tender. Unfortunately, while that solved one problem, it created another when the unbalanced weight distribution caused it to sometimes derail on curves. It did eventually work, as I recall.
