Surveillance Camera Specification Guideby John Honovich, IPVM posted on Aug 19, 2013 About John Contact John
This 28 page report provides the most in-depth guidance on specifying surveillance cameras.
Specifying cameras correctly can be hard, as many factors impact performance and 'best' practices are prone to major errors and manufacturer manipulation.
RFP reviews show a sad tale - RFPs copied from more than 10 years ago, vague and confusing ones, specifying older tech at extremely high costs, systems costing 20x more than planned and systems underestimating needs and then failing.
The Big 3 Issues
We find 3 patterns that we examine inside the Guide:
- High level specifications where users think they are providing responders freedom but make things worse
- The Frankenstein specification that literally creates a monster
- The borrowed specification that unknowingly booby traps themselves
The 5 Most Common Camera Specification Errors
Then we examine the 5 most common specific errors, including:
- Low light: confusing choices and tricks involved
- WDR: dealing with untrustworthy specs, real and fake WDR
- Resolution: how much is needed and why more can be worse
- Using PPF without the ugly downsides
- Overcoming traps in storage duration
Finally, inside the Pro section, we provide recommendations and template for another 20 common specifications:
- Transmission Type: IP vs. Analog HD
- Form Factor
- Frames Per Second
- Main Target of Camera
- Horizontal Field of View
- Distance from Camera
- Maximum Exposure Setting
- Integrated IR
- 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
