UPS Backup Power for Surveillance Guide

Author: Brian Rhodes, Published on Jan 27, 2016

Backup power for surveillance systems generally rely on batteries, especially since UPSes for computers are common and easily available.

However, uncertainty in picking the right backup power supply sized with the right batteries is a common problem, and the pitfalls of poor selection stretch beyond just having a weak system.  In the note, we look at battery backup, the most common method for surveillance power backup.

Inside we examine:

  • UPSes run time delivered
  • Understanding UPS power units of measure
  • How to calculate surveillance system wattage
  • Using runtime graphs to determine supply duration
  • How much backup runtime is needed
  • Common factors affecting runtime
  • Why consumer UPSes often are too weak
  • Why battery equipped power supplies may not be enough
  • Why commercial UPSes are often the best choice
  • Using generators for longer runtimes
