safety alarm system
11n 2. 4GHz Wi Fi radio, adding another layer of connectivity with SimpliSafe's monitoring service. 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. Components are easy to move around without damaging your walls, and you can take the system with you to your next home, which is a welcome feature. The keypad, also available in black or white and powered by four standard AA batteries, sees the biggest design improvement, with a 2. 5 inch
LCD replacing a tiny monochrome screen.
