This is one common problem we see, where industry veterans come in and grasp incredibly tightly to beliefs that were true years ago, but are now wrong due to advances in technology.

"False 'Truths'

In surveillance, take for example:

H.264 is worse quality than MJPEG"

I need to "properly interpret the words / language presented" here. With the proper bandwidth, scientifically and visually (When zoomed in), MJPEG is better. On the other hand with low bandwidth, H.264 will be better as you proved here.

Jeremiah, Please post your test results to prove that.

Beyond that, the point of that statement, and how we have heard people say it, is that H.264 is fundamentally worse quality, people just use it to save bandwidth, which is wrong. Please, I really no one believes anything like that.

Related, many people have no idea what compression levels are and think resolution is the only thing that impacts quality is resolution / pixels.

I agree with the main point that too often we let our knowledge get rusty. Thats definitely not something you can let get rusty.

Best,

John

My only comment is we should have such a problem that their ideas are only 10 years out of date. Try 15-20.

Agree and as mentioned, very difficult to keep up with such rapid changes. Its one of the reasons I like IPVM, you do most of the work for me & I just have to read up. That said, I wish every end user was an IPVM member & actively utilized the sites when comparing bids. I can't tell you how many times I've lost a project to an inferior submission because the competition went in with something lame & poorly designed but cheaper. End result is customer is stuck in old technology with a system they aren't ecstatic about, has no migration path for the future and I lost the deal by a pittance (as low as $200.00!). If only the customer had been better educated on exactly what he/she was signing up for they would have thrown out old technology bids and only compared the right technology bids. I would still have had competition & may have lost it but at least I'd know the customer was getting a good project. I encourage every end user I talk to to join IPVM!
