The SimpliSafe web page said customer service is open EVERY DAY from 9am to midnight. Said nothing about holidays. That taken into account...where I live we have these little things called Hurricanes that can cause evacuations and knock out power for weeks on end. I understand the base station batteries only last for 24 hours. What happens when the power comes back on? And, does SimpliSafe Recommend any other equipment to keep the system running longer than 24 hours?
