Rant: did a system upgrade in an old house and now I'm second guessing everything

I was swapping out a 20 year old DSC panel in a house built in 1923 over in Portland last Thursday. The homeowner said they never had a false alarm in 15 years, but I had to change six dead sensors. Got me thinking - are we making systems too sensitive with all these new gadgets, or are the old ones just unreliable? What do you guys think, is newer always better or are we creating more problems?

Those old houses settle so much even the door frames get crooked over time.

Man, that humidity thing's a real pain, I feel your frustration on that one.

Portland old houses and old DSC panels, I've seen that combo go bad in weird ways. The thing nobody talks about is that those 20 year old sensors used actual magnetic reed switches that required a pretty hard physical contact to trigger. New sensors are all Hall effect or digital hall sensors that pick up on the tiniest movement. I had a job in a 1910 craftsman where the new window sensor kept tripping because the old wood frames would expand and contract with the humidity, causing the slightest wiggle. The old system just ignored that because the magnet had to be practically touching the switch. So it's not just about false alarm sensitivity, it's about how the house itself behaves differently with modern components. You might need to add some deadzone or debounce settings in the new panel config if it has them.
