Multi-Imager Camera Guide

By: Ethan Ace, Published on Jan 02, 2018

Multi-imager usage continues to grow, with most manufacturers now offering at least one model, making them an attractive option for covering wide areas compared to multiple fixed cameras traditionally used, such as this ~200' wide parking lot:

In this guide, we review key issues impacting multi-imager camera selection, including:

  • Multi-Imager Basics
  • 180° Vs. 360° Vs. 270° Models
  • Separate Streams Vs. Stitched Views
  • Stitched View Aspect Ratio Issues
  • Rotated Imagers vs. Standard
  • Multi-Imager Licensing
  • Integrated IR
  • Advantages/Disadvantages Vs. Repositionable Multi-Imagers
  • Image Details Vs. Fisheye Cameras

For reference, users should also see our Repositionable Multi-Imager Camera Guide and Fisheye Panoramic Camera Guide

Great Article

I am a fan of the repositionable style. Particularly with each head have a varifocal lens. Corner mount 270 degree, each with a wide or narrow FOV are versatile. Also at "T" hallway locations. They are bigger however not 2 or 3 times bigger. The prewire is easier .... They are sometimes not as movable as one would like however that is the size tradeoff.

rbl

For reference, also see our Repositionable Multi-Imager Camera Guide.

I would say that some of the repositionable models are 2-3 times bigger than 180/360 models. The Hanwha PNM models and Axis P3707 are quite wide. The Avigilon HD Multi Sensor and Arecont Omni models not so much. They're not much bigger than other multi-imager domes.

This is great stuff.  In your comparison between fisheye and 180/360 multi-imagers, what models are used?

That was a Hanwha PNF-9010R for the fisheye, and Pelco Optera for the 180/360 examples. 

Which were the fixed 180 degree cameras shown in the image?

Ethan,

Do you have any bit rate statistics for these cams?

One would like to think of them as simply X number of single cams, but real life does not support that notion completely.

Hi

Personal experience. Multi imager that don't stitch are useful. No doubt. T For a camera that calls itself "panoramic", stitching should be standard. It shouldn't be the exception.

 I believe we all have been in situation where the customer expected stitched images when buying "Panoramic" ... That disappointment however slight will result in lost sales at one point or another.

On that is there a list of Panoramic cameras that perform stitching? VMS that can do stitching? Those lists would be much welcome as the manufacturers are very obtuse about stitching...
