Super Low Light Surveillance Guide

Author: IPVM Team, Published on Aug 01, 2017

At the beginning of this decade, low light performance of megapixel cameras was generally terrible.

This was the era of super slow shutter where 'ghosting' was a common tradeoff of brighter low light images.

Now, a lot has changed.

The rise of integrated IR is certainly one major improvement with literally most camera models offering their own IR 'lamps' built-in.

Another major increase is the rise of what is often called 'super low light' - achieving superior low light video without depending on IR.

In this guide, we explain super low light covering:

  • Enhances in image processing / gain control
  • Expansion of cameras with larger imagers
  • Introduction of professional photography sensors to security cameras
  • Image quality relative to conventional cameras, integrated IR and thermal cameras
