Fisheye Panoramic Camera Guide

By IPVM Team, Published Jan 18, 2022, 12:02pm EST (Info+)

Fisheye panoramic cameras are common but, because their lenses are fundamentally different than conventional cameras, their capabilities and tradeoffs are frequently misunderstood.

However, with many options, it can be confusing to understand the tradeoffs. In this 20-page guide, we explain:

  • Why Use Fisheye Panoramic Cameras?
  • Fisheye Panoramic Basics
  • "Warped" Fisheye Video and Dewarping
  • Camera-Side vs Client-Side Dewarping
  • VMS Dewarped Stream Integration
  • VMS Virtual PTZ Control Limitations
  • Camera-Side Dewarping Recording Limitations
  • Client-Side Dewarping Basics
  • Client-Side Dewarping Drawbacks
  • ImmerVision "Open" Dewarping SDK
  • Fisheye Lens Types
  • Stereographic And Panomorphic Lenses
  • Fisheye Mounting Height Impact
  • Ceiling Vs. Wall Mounting
  • Wall Mount Only Fisheye Cameras
  • Fisheye Model Availability
  • True WDR Panoramic Performance Improvements
  • Panoramic Low Light Weakness
  • IR Panoramic Availability
  • Image Detail Vs. Multi-Imager

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