Had a customer in Phoenix who insisted on hiding a motion sensor behind a curtain
This was about three months ago, a residential job in a nice suburb. The guy wanted a motion sensor in his living room, but he didn't want to see it. He pointed to this heavy velvet curtain and said, 'Just put it behind there, it'll be fine.' I explained, slowly, that the fabric would block the infrared and the sensor would be useless. He got this look on his face and said, 'But it's a smart sensor, right? It should just work.' I had to pull out my test unit and show him how it wouldn't trigger with the curtain in the way. He finally agreed to let me mount it on the corner of the wall, but he was grumpy about it the whole time. Ever have a client who just will not accept how the basic tech works?
