i have motion sensor lights,you have to break 2 beams so animals dont set it off, motion sensor cctv battery operated £75, i have those road works low steel barriers placed just inside the gate on rubber pads and connected to my electric fence with a gap to the side for me only i know that bit isnt live. if anyone grabs that during the night you would hear it as ive walked into the fence in the dark and it makes you shout. MARK, no offence but youre a dreamer, you put a loads of expensive stuff in a field and are surprised when it gets nicked. and those long dark lanes are the best places to nick from..... with all the birds i have and other stuff £200 isnt a lot to deter thieves,(and foxes). MARK and others, people will take you stuff and always have done. ELECTRICUTE THEM almost.
