Top 5 IP Camera Mistakes

Author: John Honovich, Published on Sep 26, 2013

IPVM trains professionals from all over the world. We have found 5 particular mistakes that are common and critically important.

To help, we have prepared the following 5 minute video to explain and correct them:

Over 1000 of you have viewed this in the first few hours. The part most repeated is the pixel count table. Here is an excerpt of it. And, yes, you definitely need to memorize this. No excuses.

Memorizing this will not make you an expert but will let you work on more critical calculations and advanced estimates.

You nailed it John, that's a lot of great information in a five min video. As a recent grad of IPVM U I actually found it was a nice quick review. Thanks.

John, about the apple video. Compression value 90 gives a better picture than compression value 5? I think it's opposite.

Enlightening!

One question doesn't the slide of the apple showing res/comp have the compression numbers reversed, (as well as the audio stream)?

On all cameras i can remember, but specifically say Axis, the HIGHER compression number means LOWER quality...

I always thought it was a rough percentage of how much information was lost...

Pekka, Chris, good eye. The numerical scales for compression can be very confusing as manufacturers use both - high numbers mean high compression sometimes and other times high numbers mean low compression.

We have updated the slide in the video to say 'low' or 'high' to make it easier to understand the concept.

Indeed, the best way to truly understand how much compression is being used with H.264 is to use a stream analyzer and discover the actual quantization level selected. This allows comparing across manufacturers.

For those who care about video quality, I highly recommend our How to Measure Compression Tutorial that explains this in depth.

These are great tips for everyone to reveiw. I have never completely understood the F-stop but I do now.
