CYPER

Google Street view images are from 2012, so quite old. Recently the exterior of the building has been renovated and thermal insulation installed, so it looks like this now: The issue is that most residents don't mind the installation as long as they don't have to pay for it, thus I am footing the bill for the equipment and the electricity will be shared between the car owners. I might be able to install the RIP at the entrance, but that means 2x 10m cables running down to the sensor and then up again to the floodlight, which is doable I guess. Existing car park lights belong to the city and they certainly don't work if they are even there. I don't need to cover the entire area, just around the right block entrance, so half side of the block. So like 10x10m area max. Each apartment has its own owner/landlord. There is no central authority here. People are poor, nobody wants to spend any money. I have already purchased the flood light and will be doing this myself with the help of a few other owners. There are 3 apartments per floor, so 45 in total for the right entrance.

Same as UK: 230V It's for a flat I own in Bulgaria. Here is a view towards the mounting position, 4th floor roughly 10m height: https://goo.gl/maps/trd8ABzG7xrDMPJ78 I have spoken with a few neighbours + the block manager and they are all happy with the idea as it is for the benefit of the entire block. When people are coming home at night or there is someone in the parking lot the light needs to activate. I am paying for everything, so trying to keep costs down. Managed to get this LED floodlight for £25: https://www.amazon.co.uk/gp/product/B01LWKC0G0/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

What further information is needed to understand the full picture?

I am not looking for an all in one unit, but separate. I have permission to install it, it is not in the UK. But height is a relative term. If we vusually rotate the block of flats 90 degrees then its face will be the ground and so installation will be at ground level. And the parking lot will be like the opposite wall 10m away. If I adjust the mounting angle of the sensor would it work? Most cheap sensors have a max distance of 12m.

I live in a block of flats on the 4th floor and want to install a LED floodlight triggered by a narrow angle movement sensor. There is a parking lot in front of the block and the installation height is around 10m. Can you recommend a movement sensor to detect people walking downstairs but not across the entire parking lot. Also what floodlight wattage would be sufficient for 10m height? There are 100,200,400,500,800,1000W on Amazon. Thank you.
