Repositionable Multi-Imager Camera Guide

By: IPVM Team, Published on Dec 22, 2017

Multi-imager usage has been growing strongly over the past few years.

Now, a new segment of multi-imagers has taken off, with many manufacturers offering repositionable models enabling the user to pan and tilt the cameras to customize the field of views covered.

Below is an example of positioning one such unit:

Inside this guide, we explain the following key elements in repositionable multi-imagers:

  • Number of imagers
  • Fixed vs. varifocal vs. motorized lenses
  • Positioning/panning differences
  • Motorized positioning
  • Tilt limitations
  • Corridor mode support
  • Size tradeoffs
  • Resolution and FPS options
  • Advanced features (WDR, super low light, IR)
  • Comparison to single imager cameras
  • Comparison to fixed lens multi-imager cameras
  • Comparison of Arecont, Avigilon, Axis, Hanwha, and Vivotek repositionable offerings

Repositionable Multi Imager Introduction

Repositionable multi imagers consist of multiple camera assemblies (lens and sensor) mounted in the same housing, each typically with its own 2 or 3 axis gimbal for individual positioning.

There are three key variances in repositionable model coverage:

  • Number of imagers: Most commonly, four imagers are used, but three and two imager models are available from some manufacturers.

  • Fixed or varifocal: Repositionable multi-imagers may be either varifocal or fixed focal (with interchangeable lenses). Varifocal models are growing in popularity in the past ~12 months.
  • Motorized zoom/focus: Additionally, some manufacturers include motorized focus and zoom in their repositionable models, allowing users to aim cameras in the field and fine focus/zoom remotely.

Imager Panning Differences

How individual imagers are positioned also varies, with two broad categories:
