Panasonic Smart Coding Tested

By Ethan Ace, Published on Apr 11, 2016

Panasonic is the latest entrant in the smart CODEC trend, introducing their own version, called 'Smart Coding' as a firmware update to nearly their entire existing line, with claims of up to 70% bandwidth savings "without sacrificing video quality."

We tested this new firmware against smart CODECs from Axis and Hikvision to see how it performs and whether it lives up to these bold claims.
