Some systems are mesh, as you have some wiring, receivers can likely be distributed throughout the system if it's really necessary. Pneumatic drills with decent bits fly through engineering brick or even concrete and rebar. I have yet to find a job that's not possible... Two sensors on a 6-core is possible via EOL wiring, which most systems are now. For control panels they mostly do the same stuff and every installer has there own preferred kit they have trained on, if your DIY'ing a one off it probably doesn't matter. Proper systems are not designed for installation by end users, so your not going to find reviews. You will possibly also struggle to get manufacturer support or manuals at all.
