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

The keypad, also available in black or white and powered by four standard AA batteries, sees the biggest design improvement, with a 2.
