Burglary Protection: Planning Outdoor Lighting with Sensors

Also quite in the dark.

Sure, the onset of darkness usually serves as an indicator for the bastard whether someone is home or not, so I may have expressed myself imprecisely. I rather wanted to point out that it is not as often assumed that the burglar comes at night. Light never hurts, and the burglary-deterring effect on ground floor doors/windows certainly makes sense. My remark is more in the direction that besides a basic "minimum security," one should definitely consider their individual situation and also exactly what they want to protect themselves against, since advisory services often go overboard and recommend the maximum package. I just read this today and found it funny: "For a safe home - Classic and smart video intercom systems". Depending on the property, this can be a nice useful thing, e.g., in an ordinary single-family house, the protection against burglary tends toward zero. Ultimately, it is like with the heating, the controlled residential ventilation, or other technical things in the house; the builder should carefully consider what exactly is appropriate for their very individual situation.

....maybe this is so rare because it makes little sense

I would find the crawl-under protection quite useful. If the burglar approaches the building because you haven't covered every meter of the garden with motion detectors and moves along the facade to his entry window, the lamp would trigger with crawl-under protection. Without crawl-under protection, as unfortunately very few have, he can move close to the facade without it lighting up. Right?

I would already find the under-crawl protection useful. If the burglar approaches the building because you haven't covered every meter of the garden with motion detectors and moves along the facade to his entry window, the lamp would go off with under-crawl protection. Without under-crawl protection, as unfortunately very few have, he can move close to the facade without it getting bright. Or not?

If it reassures you, then you should do it. There is no proof whether it helps or not. If you want to exclude any approach by a criminal, such as "crawling under" to your house, it becomes a never-ending story, and in the end, it still turns out differently. As also wrote, it is mainly about making it as difficult as possible for the burglar to break into your house—you cannot prevent it anyway. It is about conveying to the "ordinary" home burglar that it might be easier in the house next door. Burglars are usually quite lazy and want quick success. Therefore, equip hardly visible side entrance doors, windows/patio doors on the ground floor with proper burglary protection. That seems to me to be sufficient and adequate protection against home burglars. If you want to protect yourself against other things or are afraid of something (unpleasant people at the door), then just use a peephole in the door leaf or an intercom system. In general, for me, it is just too much spraying everywhere that is done in this area to supposedly live safer.

Security is subjective. As previous posters have already written, more than just light is needed. A dog (no matter how big) deters more. There should also be sufficient mechanical protection.

Be clear about how much "security" you want or need and what you are willing to spend.
A proper security concept involves many areas and costs accordingly.

Mushroom head locking on windows would already be the first step for opportunistic burglars.

Therefore, equip hard-to-see side entrance doors, windows/patio doors on the ground floor with proper burglary protection.

And that hard-to-see door can even be under floodlight – the organized burglars know exactly where to go to avoid being seen.
Anyone who looks at their house from the visitor’s side with open eyes will “see” the areas that are not visible.
But everything that seems subjectively safe should also be implemented.

For example, we don’t have much security apart from mushroom locks, a visible dog food bowl, and on the terrace there is a coffee cup, shoes, and garden tools lying in front of the patio door, which look like we just quickly dashed into the house. I arrange that before every vacation, and then I also feel comfortable.
