I missed the following out originally, as I didn't want to give out too much private information.
I've recently had a spate of things, such as an attempted burglary (I shouted at the culprit(s) (there were between one and a few culprits, at different stages of the break in attempt), the Police were in attendance, as the culprit(s), may have been hiding), EDIT:**possibly actual burglaries (unsure if they managed to get in or not, some signs of damage/messing inside, but not 100% conclusive) and significant damage to a number of things, outside.
It is costing thousands of pounds, to put things right. But some of the things could have done with being renewed, anyway. So, the real cost is hard to estimate.
E.g. They smashed up a window, a few days ago. I don't know if it was the same culprits, but I suspect it was.
I might be at risk of physical harm, so I have to deal with the immediate threats, and try not to confront them, myself.
The Police and other people, know that other property(s) in the region (Town), have had possibly similar issues, but it could also be unrelated.
Some (e.g. The Police) think that these are targeted attacks, and they are seeking out certain properties, on purpose.
As others have kindly pointed out (both in this thread and through other communication, mediums), thanks!
This situation and my CCTV requirements, don't have the time to wait for me to mess around with Raspberry PIs and stuff, taking many months or a year, to eventually sort out what I need.
So, I need to take what immediate steps that I can do now (thanks for the advice!).
Such as activating any existing cameras, I can very quickly get to operate, such as a wildlife camera (with internal SD card, and passive IR detection to start and stop, recording, which I can put in a suitable spot, quickly), I've got, but not used yet.
Panic alarm(s), as it is getting risky, if intruders manage to break in.
My overall physical home security, is being improved, on an ongoing basis. Making it a lot tougher for intruders to get in.
So a professional CCTV company, can rapidly access the actual specific building layout, and devise suitable solutions, given the exact situation.
Also, as already mentioned. Lighting is extremely important. So I intend to have the existing security lighting situation, significantly improved.
I feel a bit like when a beginner, starts a thread, saying something like, they feel they need a 200GHz 16 channel oscilloscope, to start learning about electronics for the first time. So, they have decided to start off by building their own, 200GHz oscilloscope from scratch, using some transistors they bought for $0.99 on ebay, from China. How hard can it be?
EDIT:** Most likely, nobody, actually broke in. But there was an attempted break-in (while I was in, I heard it (loud bangs) and went to where they were trying to break in, and shouted, which worked, and they ran off, to (what I presume, as I saw them all together, when I searched the street for the culprits, a couple of minutes or so, later) meet up with a few others, in the street or on the other side of where I am).
E.g. (There was a lot of electronics stuff, where I was most suspicious, they may have been), but they would have disturbed a number of things, in that area, just by messing around there. But everything I've looked at, seems to be where it was, from before the incident(s).
Such as a set of resistors (on cut tape, through hole, 1/4 watt, with perhaps 10 or so, on it), which had fallen, and were only just stopped by something, from dropping onto the floor, about half-way up. I'd noticed them a while ago, but (lazy) didn't bother to put them back where they belonged.
