We definitely have these digital "trip wires" set up in various places. They are solar powered, and require no maintenance. The cool thing about them is the receivers all work on the same frequency. So you can have 2 tripwires, and 5 receivers. We have 1 in the house, and 1 in the grow op. 1/4 mile range, even in a metal building. Cheap too. I've had mine for about 3 years, no problems. You WILL get a deer, or rabbit trip it at 3 am, but it don't happen that often.I’ve heard people using drive way monitors. Super cheap . Sends audible alarm to unit inside when invisible line is crossed.Downfall, wildlife can trip them but you might want to know about that too.
