New Technical Article Provides Suggestions on Saving Time and Money in Installs.

Kris Nickeson, 3xLOGIC’s Technical Services Manager has written an excellent article detailing methods that will save installers time and money on every install.
The article is only available to our Authorized Partners and can be found in the private forums at: http://www.3xlogic.com/partnerforum/save-time-and-energy-installs.
Here’s a little excerpt from the article:
"So take a minute. Set it up on your demo box at your shop. Test that new IP camera on a simple setup, with a DVR, switch and camera. Remove all the unknown variables from your testing equations by keeping it simple and doing one test at a time, in a controlled environment, with known-good parts and equipment. Realizing you don’t have the proper dipswitch settings on your PTZ a day and a half after you returned the $500/day bucket truck is not how you want to end your install. Some of those cameras installed on the roof that you can’t seem to get working on your network may have been setup in 3 minutes in your shop on a controlled network. Now that they’re unreachable, some very valuable test are extremely time consuming. Is it my cabling, or a bad camera? That’s easy to test on a simple switch/DVR/camera setup with a known-good, prebuilt patch cable. It’s much harder to determine the cause of failure once the camera is 300 feet away on a roof somewhere, in a housing, running through 3 network closets & 4 routers. It happens, believe me."

Thanks
I just wanted to express my gratitude to everybody who has anything to do with the creation of this resource.
testing setup
Yes, I also have a grey-scale and resolution test chart, tripod, etc., for testing under known-good conditions. Not only for an introduction to a new camera or to try to check claims such as low-light performance, but to burn in a unit or software.
But there seems to be no standard for common camera performance criteria, such as low-light, actual output resolution, infra-red performance, etc. For example, what does a low-light number such as ".5 lux" mean?
Sensitivity measurements are well known and standard for decades for FM radio: it states the signal level required to produce a given level of output.
In video production, there is a standard chip chart that produces a standard waveform that is measured, 0-100%. With the iris set at some level, what light level is required to produce 100%? One can measure this stuff.
But in surveillance camera specs, there is no reference information--no standard target chart referenced, no camera info provided (iris, auto on, etc.), no standard output waveform--just an unsubstantiated number.
Any thoughts?
Mike
