Smart CODEC Guide

Author: IPVM Team, Published on Nov 29, 2016

Smart codecs are a next 'big thing'.

With cameras having more and more processing power available, it is enabling them to make 'smarter' decisions about how they compress video.

The marketing names will vary. Some include 'Zipstream', 'Smart Coding', 'H.264+', 'Smart Stream II' and more. It is also critical to keep in mind that the implementations and bandwidth savings can vary dramatically.

In this Guide, we explain what Smart CODECs attempt to do and the most common implementations.

To understand this, you must have a good understanding of CODECs, compression and bandwidth variations. Please first review our:

'Normal' CODECs today, like 'regular' H.264, set one compression level, one I frame interval. 'Smart' CODECs change one or both of those, reviewed inside.
