Depends where you live I suppose.
In the greater vancouver area (Canada), I use US based Alarm.com
The system is great and convenient with lots of system features, zwave stuff, automated locks etc.
A few months ago our house was broken into. I was about 10 minutes away. I raced back and was greeted by 3 RCMP cars blocking my driveway, they were already inside sweeping the house.
We lost nothing. The guy broke in via a rear window and sensor logs show he raced around the lower floor, missed easy pickings, pulled the knob off our stereo cabinet door, dropped it and exited via the rear patio door in under 2 minutes, and got away (until a couple weeks later a few blocks away).
Earlier, my wife entered the unlock code on the door incorrectly, and inadvertently entered the duress code. I got a push notification on my alarm .com app, checked the sensor log and felt it was likely a false alarm. I called my wife to check in, she hadn't realised from the symptoms that she'd triggered the duress but it made sense to her in hindsight. I assured her to expect a knock at the door shortly, and sure enough, again the RCMP were there, insisting a thorough check of ID, an interview, and a tour of the house.
I couldn't be happier with the performance of the system and the service. Far better than I had in the past with ADT, Chubb, etc. even in the same house with the same police force, the response was not that good, and in fact before I switched, I got a letter from ADT saying that there would no longer be a police response unless the monitoring company was able to connect to the home owner and the home owner requested it.
On the other hand, no Neighbors, heard, noticed, or responded.
