An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup, is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or flywheels. The on-battery runtime of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment.

Surge protection is a smart investment in preventing not only equipment loss, but the potential loss of critical information.
Possibly the surveillance video itself.Emerson Network Power recommends the following:
1. Install surge protection devices on all components connected to wiring entering or exiting a building.
As detailed in the diagram below, a typical surveillance system is directly or indirectly connected to a building’s main
electrical service panel. AC power, data lines and coaxial cables...are all vulnerable to surges and transients. A single
surge event affecting exterior equipment, (like cameras), can follow a path leading back into a building, affecting interior
equipment as well. DVRs, interior cameras, midspans and power supplies may not have received the initial surge, but
because these components are connected, the entire system is at risk of damage or even destruction.
2. Install surge protection devices directly on the electrical service panel, along with each individual piece of
equipment (both interior and exterior).
The risk of damage from a surge event isn’t limited to only the interior and exterior video surveillance equipment...
loads, such as HVAC units, lighting and signage can be affected by a surge event occurring elsewhere.
