Maybe if you open it up and have a go!
However, I'll be completely honest and hopefully it does not upset... unless you have line of site, these are almost useless.
I would never use one again, I tried one to get me out of a situation with CCTV and a client wanting to view it in the bedroom about 2 meters away but through a wall.
In the end we lifted the floor and ran a cable... things are as useful as a ashtray on a motorbike!
