Surveillance Camera Specification Guide

Author: John Honovich, Published on Aug 19, 2013

Anyone reviewing RFPs knows there are countless common problems, with 'good' specs seemingly few and far between: RFPs copied from more than 10 years ago, vague and confusing ones, those specifying older tech at extremely high costs, systems costing 20x more than planned, and systems underestimating needs and then failing.

In this 30+ page guide, we look at top issues impacting specifications, camera specs that cause the most trouble, and give recommendations for over 20 different spec areas.

The Big 3 Issues

We find 3 major patterns that we examine inside the Guide:

  • High level specifications where writers think they are providing responders freedom but make things worse
  • The Frankenstein specification which literally creates a monster
  • The borrowed specification that unknowingly booby traps the design

Top Specification Trouble Spots

Then we examine the seven most troublesome areas of camera specifications, including:

  • Specifying camera target and field of view
  • Using PPF without the ugly downsides
  • Resolution: how much is needed and why more can be worse
  • Low light: the many confusing choices, technologies, and tricks involved
  • Integrated IR: how to realistically specify integrated IR cameras
  • WDR: dealing with untrustworthy specs, true and fake WDR
  • Overcoming traps in storage duration

Finally, inside the Pro section, we provide recommendations and template for over 20 other common specifications impacting camera hardware and software features:

  • Transmission Type
  • Form Factor
  • Frames Per Second
  • CODEC
  • Maximum Exposure Setting
  • Audio
  • Outdoor Rating
  • Temperature Range
  • Vandal Resistance
  • Multi-Streaming
  • Streaming Mode
  • Recording Mode
  • On Board Storage
  • VMS Compatibility
  • Power Supply
  • Auto Focus
  • Iris Type
  • Lens Type
  • PTZ Optical Zoom
  • PTZ Pan Range
  • PTZ Tilt Range
  • Digital Zoom / Total Zoom
  • Panoramics vs PTZs

Pixels *** ****: Choices - anywhere from 10 ppf to 100 ppf: use 10ppf if you just want outlines of people and cars, use 50ppf if you want to see details of face / license plates; go even higher if you want a higher margin of error / more robustness to environmental / lighting issues

Horizontal ***** ** ****: Choices - any width you want but must be specified with a pixels per foot metric - critical to defining resolution; common reference widths - double doorway ~6 feet, two lanes road ~ 25 feet

Distance **** ******: Choices - generally 5 - 50 feet; this is an optional specification; however, if provided helps integrator choose the correct lens length

Low *****: Choices- mechanical cut filter or color only; if you have poor lighting at night and need to see, require mechanical cut filter

Maximum ******** *******: Common Choices - 1s to 1/10,000; Recommendations - 1/30s to minimize motion blur at night; up to 1s if you are OK with significant motion blur but want a bright image

Frames *** ******:  Choices- typically 1 - 30; atypical up to 60; Recommendations - if you do not have regulations or legal requirements, most surveillance video is fine with 5 - 15 fps
