The Wi Fi is a boon for those living in rural areas who wouldn't be able to use the monitoring service because of patchy cellular coverage. If you're concerned about IoT threats, you don't have to connect SimpliSafe to your Wi Fi network, the monitoring works just fine without it, though you won't receive firmware updates. Inside the base, there's a siren, a backup battery the company claims will last up to 24 hours, and a SIM card for cellular communication. The entry sensors are also redesigned, and are much smaller about half the length they were before, squarer, and modern looking. They're powered by inexpensive, user replaceable CR2032 coin cells that should last an average of five years, and the system will warn you when they need to be replaced. Installation requires no wiring or drilling; I simply
pulled off the battery activation strips, peeled the backing on the 3M Command like strips, and adhered
each component after naming and pairing it with the system more on that below.
