Fisheye panoramics have become widespread, with most manufacturers offering fisheyes.

However, with many options, it can be confusing to understand the tradeoffs. In this guide, we explain:

  • Why Panoramic Camers
  • Fisheye Panoramic Basics
  • 'Warped' Video and Dewarping
  • Camera Side vs Client Side Dewarping
  • VMS Integration
  • Fisheye Mounting Heights
  • Ceiling Vs. Wall Mounting
  • Panoramic WDR Availability
  • Panoramic Low Light Weakness
  • IR Panoramic Availability
  • Image Detail Vs. Multi-Imager
  • Fisheye Manufacturer Availability

Multi-imager panoramics, a common alternative to fisheyes, are covered separately in our Multi-Imager camera guide and Repositionable Multi-Imager Camera Guide

Well done.

Great article! One thing I've always theorized, but have never been able to test is the potential downside of using client side dewarped fisheye panoramics use of additional client PC resources when dewarped. I'm sure this is negligible if dewarping one or two, but if you have a large amount of this style camera being dewarped it could be an issue.

Fisheye camera seems interesting but cost more...

The idea is you get more coverage with a single fisheye camera versus multiple fixed cameras which is how you save money with fisheye cameras.
