Dahua Smart H.264+ Tested

Author: Ethan Ace, Published on Aug 17, 2016

The smart codec trend continues, with Dahua adding Smart H.264+ to many of their models in new firmware.

In this test we see how it performs and how it compares to Dahua's key competitor Hikvision and their H.264+ smart codec in day and night scenes, both low and high motion.  

For more Smart codec details, readers should see our Smart Codec Guide as well as tests of Axis ZipstreamHikvision H.264+Panasonic Smart Coding
