David, we have tested 3 manufacturer's smart codecs and they work very well to reduce bandwidth / storage. We highly recommend them.
Smart codecs still have limited overall availability and knowledge of smart codecs remains low in the industry, but we'd encourage you to use them.

Thanks very much, John. We'll focus on these models for applicability in our environment.
I have been using Panasonic's smart codecs for about a month now I havent had any issues other than compatibility with mobile apps which they should be fixing here shortly.
its really useful if you have 4K or 30-60fps environments

Thanks for the feedback, Eddie. IPVM review was pretty positive, as well. We're looking seriously at them.

Just started using smart codec for Panasonic WV-SFV481 replacing a Sony SNC DH140
substantial savings on storage Sony camera used 100 GB for 14 days Panasonic used
22 GB for 14 days.
so far i have had these results with Panasonic
720p 30FPS smart codec 270kbits with no motion , motion ~2Mbs
1080p 30FPS smart codec 700-800kbits no motion, motion ~ 3.8-4Mbs
4K (SFV481) 15FPS (max setting) smart codec no motion 1.5Mbs, motion ~ 8-12Mbs
i haven't got my hands on a 7 series yet that run full steam at 30 FPS probably wont for a while since they are about $2K and fugly.
when the camera has motion it ramps up so it only advantageous if you record 24/7 or view live over a small bandwidth connection
I am currently testing SamWha TechNet smart codec for their wisenet lite series if i can remember I will post those some where
Looking at the zipstream review John posted above
Testing Axis Zipstream
it looks like Axis enables the possibility to have the a Zipstream camera dynamically alter the GOP, with a default maximum GOP of 1200. At 10 fps this could be an I-frame every 2 minutes. So I am wondering how much strain dynamic GOP could place on certain features in a VMS (in the worst case).
An example is playing footage in reverse, or step-back. For instance, when stepping back, the VMS software has to go back to the previous I-frame and decode every subsequent P or B frame just to get the previous image. In the worst case, this implies that the result of clicking a step-back button will mean decoding 1 I-frame and then 1198 P or B frames, which I guess would work, but could be annoyingly slow, especially for high resolution video. I have similar concerns with thumbnail/scrub searches that only display I-frames.
Anyone encountered any problems along these lines?

Thanks for the info, John. This gives me a better understanding.
