Surveillance Cameras on Light Poles Tutorial

Author: Brian Rhodes, Published on Mar 18, 2013

A growing trend makes putting surveillance cameras on the most logical choice in parking lots - light poles - very problematic. Increasingly, power is switched on, and more importantly off, via a centralized source. While this may be great for conservation it creates havoc for security cameras that need to run continuously. In this note, we explain what switch power is, why it is a growing trend and what solutions are available.

Switched Power Defined

In high-voltage applications, switched power refers to energizing or de-energizing entire circuits at main electrical distribution panel. Rather than individually turning off lights or outlets with breakers / switches, an entire area is designed to have power cut off at one central spot.
