I am sure I have it wrong but the reason I wanted to use different frequencies so that I know which area there some thing going on, scenario alert sector 1 means some ones coming up the drive way I will have a motion and under drive way detector on that... Alert sector 2 means deer are in at the feeder and maybe alert sector three means some ones around the pole barn you know what I mean and the wife will know what each sector means and so I know where to look to see whats going on so they all dont say alert sector one and I will have no clue where or what its alerting me to..Please explain if I have it wrong, thanks Brent
