Video surveillance IP cams, NVRs, servers etc.

If there is a break-in at our place, lights go on throughout the entire house (several hundred LED watts!) as well as 4 LED floodlights outside. Since we also have domes inside, there should be something usable on them somewhere. The cams also serve to check if everything is okay from vacation. There could also be a false alarm.

Then you at least have super well-lit footage and in Full HD (probably even 4K for you) of most likely masked people emptying your house. Yay

Seriously, I also install cams, that's not the point, but I seriously doubt that it really prevents break-ins or significantly aids in clarification. It's more of a subjective thing, but I don’t want to sugarcoat it. As mycraft already said, as a supplement to significantly more effective, passive measures that prevent break-ins.

At the end of the day, you probably still get in trouble for not putting up any signs saying "This area is under video surveillance" anywhere

Can you say something about the clearance rate of residential burglaries, and to what extent video material leads to significantly higher clearance rates? Purely out of interest.

According to police statistics, most burglaries occur during the day when people are at work and the neighborhood is somewhat deserted.

No..it's not about having usable material for me. I'm not fooling myself there. It's about two things: 1. the outside perspective for me (as already mentioned) and 2. unsettling the burglars through a lot of noise (external alarm, smoke detector, dogs barking from all speakers, lots of light, all shutters up immediately) and scaring them off immediately when the alarm goes off... I think that's not entirely unrealistic.

PS: who luckily has a home office and therefore the issue shouldn't be too problematic during the day

Can you say something about the clearance rate of apartment burglaries, and to what extent video material leads to significantly higher clearances? Purely out of interest.

No.
And if I may say so: since there is no obligation for the victim or complainant to record high-quality video material and make it available to the investigative authority, there can be no meaningful statistics on this. It is simply a "nice-to-have" for the investigative authority to receive this material in order to, for example, narrow down the time of the crime. Quite simply, the police have leads and causal chains that a citizen has no insight into. Chance may play a role here, but also traces and movement images. And this certainly does not depend on just one offense.

I have experienced this as well. The police were not particularly diligent there either.

Yes, I know that: the citizen sees a very different picture than the police.
"Back then" I was still taught: even if there is no trace image that can be evaluated by us, always do something for the complainant so that they are satisfied. So that it is not said that we are not active.

We gladly accept a nice color photo of the perpetrator at the crime scene, preferably a portrait suitable for facial recognition.

I have a Jovision Poe and soon maybe a Digoo Wifi Cam, depending on whether I can get it to work properly without an app. Actually, I would take more cameras, but outside I find it difficult to find positions where no neighbors are recorded. Also, I have not yet found the perfect software. Especially the software-based motion detection is not perfect; I have tried Ispy and go1984. For example, with the camera in the garden, spider webs keep triggering movements. Hopefully, the whole thing will eventually be integrated into Openhab and run on a Raspberry; the cameras will only be activated during the day when no one is home. The goal of my outdoor cameras is actually to detect people who are checking something out in advance. It’s my own little theory that I would never break into somewhere without knowing where I have to go.

Hello ypg

Briefly to explain: shortly after the attack (approx. 60 minutes) I was able to narrow down the whereabouts of the 3 perpetrators to an area in a street of about 20 houses with certainty. The police did not consider themselves able to ring the doorbells of these houses and ask about the perpetrators.
