"Smart Codec" was once seemingly a marketing buzzword, but in 2020, nearly all new camera models include this tehcnology.
These marketing names vary, including 'Zipstream', 'Smart Coding', 'H.264+', 'Smart Stream II', and others, and critically, these implementations and bandwidth savings vary dramatically.
In this Guide, we explain what smart codecs attempt to do and the most common implementations, covering:
- Historic static compression, I-frame interval, and FPS techniques
- Smart codec basic
- Dynamic compression
- Dynamic I-frame interval/GOP
- Dynamic FPS
- Static compression regions
- Intelligent DNR
- VMS/NVR compatibility
- Manufacturer support
- IPVM test recommendations
- Bandwidth risks
- Smart codec outlook
To understand this, you must have a good understanding of codecs, compression and bandwidth variations. Please first review our:
'Normal' codecs, like 'regular' H.264, set one compression level, one I frame interval, and one frame rate. 'Smart' codecs change one, two, or all of those, reviewed inside.
