Showerthought: Are wireless alarm sensors really as reliable as hardwired?

I was dead set against wireless for years. Thought the battery failure risk was too high. Then I did a 12-unit apartment complex in Austin where we had no choice but to go wireless. After 18 months not a single dropout. Now I'm stuck wondering if my old hardwired preference was just stubborn habit. Anyone else flip on this?

...was totally in the same boat. I had this gut feeling that hardwired was just built tougher. Then I helped a buddy wire up his house and we went wireless for the door sensors. Three years now, zero issues. The batteries last way longer than I thought they would, like years. I honestly think the tech got good enough that the old gripes don't really hold up anymore. It's hard to argue with something that just plain works.

That's a fair point. I've been through this myself with a couple of installs. What I found is that the key is picking the right sensors and making sure they're mounted properly. A lot of people just slap them on the frame and call it done. You really need a clean, tight fit and to test the range before you commit. Also, a good quality hub makes a big difference. I had one system where the hub was in the basement and it struggled. Moved it to a central spot on the main floor and everything just locked in. It's not as picky as it used to be, but the basics still matter.

Wait, three years with no battery changes? No way. I swapped out my first wireless sensor after like 8 months because it kept chirping at 3 in the morning. Are you sure you're not just sleeping through the low battery alarms? My buddy tried a similar setup and had to replace two sensors within the first year because the batteries corroded inside the casing from humidity. Either you got a magic batch or the tech really did get that much better without me noticing.
