Baitpile, the sensor I am using is the "1 by One" unit. I got a set of 5 sensors with one receiver. It works very good in detecting, but the light is so bright on the transmitter that it illuminates more than the front window. It's almost like half the unit lights up. I have noticed that coyotes won't come down to the bait since I have been using these.
I started out with Driveway Patrol brands years ago, and they worked on the same frequencies then, so I purchased a few units (expensive) but it worked great. I had several sensors at the bait site and the receiver in the cabin would work with all. Now DP doesn't work on the same frequency, which is a bummer. It gave off a slight red glow, but not like these I am using now.
So, let me understand better - you are placing a red film over the window sensor? Does it still glow some? Doesn't interfere with detection?
