IR Surveillance Guide

Author: IPVM Team, Published on Jul 31, 2017

Infrared (IR) has become an increasing core component to video surveillance systems.

In particular, the expansion of integrated IR cameras that build IR illuminators within the camera has become common. On the positive side, this means that cameras can 'work' now even in the dark, even when cameras are cheap. On the negative side, many differences exist with integrated IR, including range achieved, width of coverage, overexposure, underexposure, response time to moving objects, to name a few.

In this guide, we examine these elements in detail, including:

  • The State of IR in 2017
  • Infrared Basics
  • 850nm Most Common
  • 940nm Rare, But Increasing
  • True Day / Night Cameras Required
  • Integrated IR Usage Statistics
  • IR LED Comparisons
  • Warning: No Illumination Standards
  • Range Specs Increasingly Accurate
  • But Overstated Range Still An Issue
  • Beware Low PPF At Max IR Range
  • IR Coverage Patterns Often Poor
  • Smart Vs. Adaptive IR
  • Manufacturer Terminology
  • IR Power vs. Gain/Exposure Adjustment
  • Delays Returning to Full Exposure
  • IR Impact On Bandwidth Spikes
  • Integrated IR Cameras vs. External Illuminators Pros & Cons
  • White Light Illuminators
