If meaning wireless based alarms like those mentioned from Yale, these don’t work over WiFi using a router. All of the sensor types, e.g. PIR’s, door contacts etc., are battery powered and independently communicate with the main alarm monitoring panel wirelessly. The alarm panel is mains powered but with battery backup. The batteries in the sensors and in the external siren typically last 18-24 months.
Depending on the system, some will plug into a telephone line to call out and alert up to three recipients in the event of the alarm being triggered. You can also dial into the system to set, unset the alarm remotely.
I think somebody mentioned that it’s now possible to plug cameras into these systems and those individual items will probably need to work through a WiFi router.
