Before the lights go out...I'd like to have good security lights. Right now, the ones that were on my house trigger all the time...when the trees barely wave in the wind! Are there any lights out there that aren't THAT sensitive? I'm not exaggerating when I say if the small tree moves an inch or two it goes off! I'd like something that if it goes off, I know I likely have someone in my backyard. thanks. If there's nothing better out there, I'll just dial the range way back so it'll go off if someone gets up close to my windows etc.
