Bests & Worsts Reviews from Amazon

I finally pulled the trigger on purchasing the security system to go with my 6 wired stick up cams and I am glad I waited for second generation for aesthetic reasons alone. These sensors are much less bulky and accessing the batteries will be easier that Gen 1 IF YOU INSTALL THEM CORRECTLY. In my mind I originally wanted to place the sensor side on the frame of the window's outer casing with the logic that the sensor should be stationary and the smaller magnetic side should move with the window pane but this was problematic because to access the batteries, i would have to slide the sensor to the left but it is right next to the corner of the wall. I installed that one incorrectly and will need to eventually pull off the sensor and swap the sensor and magnetic strip. The rest I installed so the sensor was on the window pane's frame and that resolved the issue. *see pictures* Also worth noting, the Gen2 sensors seem to be more sensitive than the Gen1, which I see as a plus. When the sensor and the magnet are perfectly aligned, it only takes a little more than an inch of travel to trip the Gen 2. Some of my Gen1 sensors take almost 2.5 - 3 inches to trip.
