إنذار مستشعر الحركة PIR للممر

My orders arrived in one package with multiple damages, the Box of this alarm object was not damaged but when opened, defective parts came out of the Box, I reported it at return, Now afterwards I also see that the transmitter is missing so it is also incomplete, so I wait for my return and I will order a new one, I also cannot give an assessment so it will become 1 asterisk everywhere.

You can't choose the tone when people pass in front of the detectors.

one detector works well, but the 2nd one only detects about 10 yards.

Recommended seller, the product was received for 10 days in Ukraine. The product itself was turned over

Great devices! Worked very well. I took two. By putting the batteries, the parts connected automatically, convenient!
There is one of two that does not seem to work well .. I have to take a plus close look at why ..
Otherwise, very fast delivery. Thank you
