I seem to have started to attract some door bell ringing from the local

their mates)

I am thinking of leaving a video camera running in the house - positioned in
such a way that no-one just walking past on the pavement will be caught in
shot. Then if I get a picture of a face at the window I can show it to my
local Community Police Boy.

Any legal issues that you can imagine? Anyone at the window will be 15 feet
onto my property.

Put yourself in their shoes, what would scare the **** out of you are
stop you being a nuisance?
