I have put some video cameras from my 0.7 save-file in the mailbox. The "smuggled cameras" have a very weird attribute to them.
There are no differences between the smuggled camera from the old version and the buy-able cameras from the store. They look the same, they have the same view, same features (infrared, emit their own light and remote control) what separates them from each other is that they (the untouched, bought from store-camera) can be placed down properly with Alt+R without spinning and flying into the orbit and the other one (the smuggled camera) spins like crazy until it flies into the orbit.
Only after some experimentation have I found out that only smuggled cameras have this remarkable property. Otherwise I would have never known what would have caused this and for a short amount of time I was about to give up on placing down any cameras until the next patch, unfortunately this is only an issue with smuggled cameras. This drove me crazy as I have had two cameras on my radio tower: one facing east, the other west. Through black magic, I was able to attach one of them to the tower, even though it was spinning like crazy. The other one was spinning so much that I haven't been able to find it for hours.
