As a few of you are aware 2 of our tents got robbed at Oulton Park this year and the thieving bastwards took £230 in cash and cash only (not traceable) anyhooo we've since got wireless remote PIR sensor tent alarms
only £7 each on fleabay
they work a treat
just point at ya entry/exit point when you out our go bed and use the remote to arm/disarm
should make a noise when scum's creeping round.
