Beware Out of Date Knowledge

Author: John Honovich, Published on Oct 09, 2014

You know that guy.

Confident, brilliant, tells you exactly how the world worked.... ten years ago.

One of the biggest challenges in technology is to keep one's knowledge up to date. As technology changes, so too does what is 'right'.

False 'Truths'

In surveillance, take for example:

  • "CCD is better than CMOS"
  • "H.264 is worse quality than MJPEG"
  • "Low light performance is all about imager size."
  • "Integrated IR is for cheap, low end cameras."
  • "You must focus cameras with a welder's glass."

Technology Advances

All of these, at some point, 5 to 15 years ago were true or, at least, significantly true. All of these today are, minimally, bad advice, if not completely wrong.

For example, when IPVM first started in 2008, there was a genuine debate about whether H.264 would work with megapixel cameras and if VMSes could handle that. Today, of course, that just seems silly.

And, at that time, true multi-exposure WDR was quite rare and Pixim was 'state of the art'. Today, Pixim is effectively gone and multi-exposure WDR MP is commonplace.

Of course, not everything is guaranteed to get better. Video analytics and PSIM struggle largely today as they did in the past decade.

Be Prepared / Be Aware

Technology advances but not uniformly across all areas and at varying rates.

The good advice - the cutting edge knowledge you have today - may wind up being foolish and wrong a year from now.

It is imperative to remember this and to continue to learn.

This is definitely one of the core reasons we proactively test each new claimed technology advance because some of them really do work and, when that happens, what is 'true' changes.
