Although buying eavesdropping equipment is legal, as with more things, it depends on the use and intention. The eavesdropping of people to see what someone is doing on the computer or to see where someone is driving or what someone is saying is not legal and therefore possibly punishable. Before buying eavesdropping equipment, it is therefore useful to check whether the equipment and its use are legal.
