Surveillance Camera Specification Guideby John Honovich, IPVM posted on Aug 19, 2013 About John Contact John
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
- Maximum Exposure Setting
- Outdoor Rating
- Temperature Range
- Vandal Resistance
- 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
