SD
Sorry for the late reply. Unfortunately, we don't have any close neighbours as we built the house in a developing area. Our nearest neighbour is about
500 metres away so I don't think it would be effective.
It says on the box that it has 56-bit DES encryption but i think everyone knows that already.
Sorry I couldn't be of more help or the test pilot for this but if anyone else could it would be an interesting exercise.
