HITOLIGHT LED PIR Sensor Switch Human Body Induction Controller Black 8A DC12/24V for LED Strip Panel Light Energy Saving Switch

I got this to hook up to a setup I have in my safe. I got tired of having to fish around for the remote for my led setup all the time and having to point it directly at the control box for it to work. I replaced the stock controller that came with my led's with a wifi one I can control with my phone. Setup couldn't be any simpler. for now it is just sitting at the bottom until I have time to properly run a long enough wire all the way to the top. The terminals themselves are not labeled positive or negative but it does show you the correct polarity in the instruction sheet included. It doesn't come with any mounting screws at least mine didn't which is fine because depending on where you want to mount it you might need longer or shorter wood or sheet metal screws. Sitting in my safe it can detect me at about 3 feet and the time adjustments were pretty spot on. Can speak about it in terms of longevity but it is working great. It also does not turn itself on without any motion I left it open for about 5 hours without going near it and not once did it turn on until I walked up to it. The range might be more if I didn't have it placed where it is so my range of sensitivity might differ to one that is installed somewhere more open.I received a discount on this item in exchange for an honest review.
