Optex BX-80N BoudaryGard Outdoor Perimeter PIR Detector

hi in this video I'm going to discuss and show the difference between the optics DXi which is the new generation the old one was called the BX 40 this is an vxi outdoor prr dual passive and this is called the theory the Sdn theory and also made by object these are two sensors and they are quite different in their operation while the the sensing range is considerably different for example this one senses 90 degrees which means you can set this 90 degrees so the sensor will measure 12 meters at an angle of 90 degrees the maximum is 12 meters you can reduce it while the FET series can give you 5 meters or 2 meters depending on how you set it inside and it really gives it in a straight line this is closer to a dual beam although you don't need a receiver on the other side while this one is a PIR and it kind of gives you a flood of same thing for example let me show you if I move again this
