Anyone use a driveway alarm?
I'm looking for a fairly inexpensive driveway alarm. The way my house is, I'm on a hill, and can't see when someone comes up my driveway. And, I don't like it when someone is suddenly standing at my door. It bothers me, and startles my dog. I'd prefer to know when someone is walking/driving up my driveway.
I looked at Driveway Patrol, which is cheap. But, the alarm seems annoying, and it seems like there is no way to change the distance it monitors. It seems like if I put it on my mailbox, when my neighbor mows his lawn, the thing would go berzerk! Anyone use any of these systems? I'd love something relatively inexpensive that I can control the distance it monitors, won't go off every time a bird flies by, and doesn't have an annoying noise. Tall order, I know.. but maybe it's out there.
Mighty Mule seems promising.
