Construction monitoring at a semi-detached house: Where is the best place to install cameras/floodlights/(siren)?

Hello everyone, attached are two photos for front and back views, the green half (right from the front) is mine, these are rendered photos, people are fake.
Where would you best place the construction surveillance cameras and floodlights, for planning where I need the PoE cable.
It will most likely be PoE UniFi cameras (complete network planned with them), alternatively Reolink, smart via HomeAssistant, and additional NAS for storage. I am aware of the laws regarding filming other properties, this can also be masked in the software.

I have read that the cameras should already be 3m high, but not necessarily higher so that faces can still be recognized. Would it be best to use smart or even deliberately classic motion detectors that first illuminate the garden at night? Or better to couple them, so that when the camera detects that it is really a person and not an animal, it only then switches the smart floodlight on in the garden?
Can the cameras also be well mounted on the downspout, or do the mounts come loose with strong temperature differences?
I am currently having a very hard time with this, visually it should also not be too conspicuous. Do you place them between two windows for example, or rather centered or on the edge of a window? Floodlights directly with or above the camera? Or deliberately somewhere else, for whatever reason?
A video doorbell is planned for the front, also probably from UniFi. Is that enough for the front? Or should I film the entrance area from the outer corner of the garage at an angle? Although then you would film the neighbor every time, with the doorbell you can nicely censor that, but not really from an angle.
And an alarm siren?
What do you say?

At the front, you’ve already pretty well identified the problems with the geometry – there’s not much you can do. I could at most imagine a camera mounted at the corner of the house pointing at the garage entrance.

This of course only applies to the camera – lighting-wise, you can do whatever you like. Here it would be interesting to know the phase regarding through traffic / pedestrian frequency – if you keep turning on a floodlight constantly, you won’t make any friends with the neighbors...

At the back, I would coordinate with the neighbor – but generally, you’re free there. In the middle between the windows for the camera and a floodlight on each the right and left side is always possible. Important: switchable – otherwise garden parties won’t be any real fun.

Not at all. Would do without them.

I read that the cameras should already be 3m high, but not necessarily higher so that faces can still be recognized.

That is not entirely correct. Whether you can recognize faces depends on the resolution as well as the quality of the infrared light and focus setting. You need less floodlight, rather light with a motion sensor. And not in floodlight quality either, because that washes out the details of the culprit due to overexposure. Three meters height is therefore appropriate so that the culprit cannot destroy or twist the camera with a long arm. However, you film more the top of the head than a face. Entry is usually from the side facing away from the street or a window with privacy protection (hedge). For the garden side, if anything, a garden shed is suitable, on which you set up the camera directed towards the patio doors. For the entrance side, you have a camera at the door, you say. That should actually be enough. Newly built housing estates are very rarely targeted. Usually there is nothing to gain there. Young people rarely have much cash at home anymore, gold jewelry is usually no longer in the wardrobe either. Close building guarantees many witnesses – so the risk that you will be targeted is not visible at all. Only certain categories of car types are interesting. Light with a motion sensor should deter the rest of the other culprits who might wander in at your place. That should also suffice for the feeling of security. Camera recordings on the phone can also make you more nervous. Ask yourself what you want to achieve with light and camera. What you get out of it. What you need it for. The police are grateful for good material, but they also don’t want to evaluate every person quickly passing through the garden. What is located behind the garden? Another row of houses? Street? Forest or field?

... from a Tecklenburg project, if I’m not mistaken.

Isn’t floodlight rather counterproductive when using night-vision cameras?

I am aware of the laws regarding filming other people’s properties, you can also mask that out in the software.

I find that problematic: you would probably have to set up the software masking so that it pixelates the area from the start. But try doing that for a camera that is supposed to pan. Edits in postproduction make the evidence vulnerable; unpixelated recordings, on the other hand, can lead to a “dismissal based on the right to one’s own image” (and successful countersuits). Why do you want to override the protective function of the identical-looking neighborhood by marking your house with surveillance equipment as the one where the person with something to gain lives? A sensible high earner disguises themselves precisely by blending into the inconspicuous area (and drives a 5 Series / E-Class like the neighbors instead of a 7 Series / S-Class). Camera, rotating beacon, and siren are also a kind of “criminal sign,” only placed by the victim themselves. Prevention works differently. If you want to stand out, do it better in the other direction: with insignia showing that a clan lives here that you better not mess with. Imagine a money-launderer’s Lamborghini in front of the house.

That looks completely different from the NoGo Area according to the description from your old thread:

Directly around this area are many old dilapidated large social housing/apartment blocks; only a few meters lie between the garden areas of the new buildings and the social housing, mostly separated by tall trees. [...]
