The sensor is working. I put it on lighting in the entrance with a low-power LED bulb. You get out of the elevator, you go into the corridor, in a second the bulb lights up and lights for about a minute. I think it's okay. The viewing angle and range did not test.

It has arrived ahead of schedule, in principle I have tested one and it works correctly is exactly what the supplier explains now I have to install them and verify the reliability and duration of them

Looks great. I did not check, but I'm sure that it will work well. I ordered 2, one set and everything is correct. Delivery to Riga-10 days. You don't have to pay the tax. Recommend.

Equal to the description of the article, I am satisfied and recommend you can even attach to another model you already have in use, just need to see how long it will last

Sensors received, several checked everything works as in the characteristic, I recommend the seller! For fast delivery, special thanks!
