Not what they used to be
Living in a very humid and hot part of the world life expectancy for anything electronic is limited so every couple of years I have to replace the 6 motion sensors we use to be forewarned of vehicles and people coming into our farm in the tropical Costa Rican jungle ,So far it s the 4th time I replaced them and they always worked flawlessly except for the ones I just replaced , they all detect and signal movement on a very sporadic and erratically basis.not something I can rely on.....!they re located along the road leading up to our premises ,the furthest ones a quarter mile away the closest 50 yards,but I switched them around so distance is not the issue,batteries are new alkaline Duracells....oh the plastic lens in front of sensor was loose and not stuck to the double tape in 2 of the brand new sensor I deployed ......that gives me the idea that quality control is not what it used to be......
