All 4 items are Brand New. Genuine Bosch Products (Made in Portugal, not in China).
It was I who opened one of the boxes to see and show you the box's exact contents.
You'll receive 4 boxes: each box contains 1 motion detector with the mounting screws, and the manual - as pictured - (as it comes from the manufacturer) - Nothing else is included. If you don't see something in the pictures, that means it's not included.
