to be fair home security systems have been using the same assumptions many years before IoT became a thing. most of them rely on cellular (can be jammed), or phone line (can but cut) or power (can be shut off).
- michaelt 10y agoI don't know about most countries, but in my country higher end security systems include backup batteries, a 'continuous monitoring' connection where a monitoring centre can detect the line being cut (e.g. in my country, 'BT Redcare' [1]), and some also include a GSM backup connection. So even if you cut the power and phone lines, the alarm monitoring centre can notice it's happened. Of course, you can buy cheaper alarm systems that don't have these features, but they're certainly not uncommon. Of course, no amount of technology can fix the fact that when the alarm triggers, the response companies often respond slowly (or not at all) making it unlikely any criminals will be caught in the act.

- kyriakos 10y agoIn my country the line detection doesn't exist but alarms do have backup batteries. I have known cases in my area of houses that got broken into with the use of a GSM jammer. Especially if a household relies on broadband telephony, knocking out the land line is a matter of turning the power off.
