Everything becomes dark. Jokes aside, power outages are serious problems, as the lack of electricity could cripple your home security system, leaving it as an open prey for criminals. Fortunately, the hardware manufacturers are well-aware of this fact, and they came up with a simple solution to counter this flaw. Every security console is fitted with a built-in backup battery that automatically activates when the power goes out. The battery life differs with every hardware provider, but at least 24 hours of backup energy is guaranteed. Also, base stations are often compatible with traditional landlines, allowing emergency calls during a blackout.
