This is the first entryway alarm where the signal and receiver work over 150 meters and then penetrate the concrete/steel walls of my home. Both DAKOTA and Chamberlain are in front of my gate. DAKOTA only sends a signal to a line-of-sight receiver located on a window sill. Chamberlain sends a signal through the concrete and steel to the closet on the inside wall in my basement! Now I know when the UPS or FEDEX guys are going to come through the gate! Pretty amazing! Costs money!
