Bosch Divar NVR Tested vs Dahua

By: Ethan Ace, Published on Oct 05, 2017

Bosch has a partnership with Dahua.

But what type of partnership is it? How much is Bosch's own vs taken from embattled mega-OEM Dahua?

We bought and tested a 16 channel Bosch DIVAR network 2000 to see how it compares to Dahua's own models, examining:

  • Software similarities and differences
  • Physical construction
  • Internal components
  • Hard disk mounting
  • Firmware features
  • Web interface similarities
  • Bosch/Dahua software discovery and operation
  • Cyber security issues

See our full findings inside.

Improved ************ Bosch NVRs use a strengthened chassis design, with a double layer of metal on the bottom of the unit, further isolating interior components from dust and vibration. By contrast, Dahua chassis has numerous mounting holes and other perforations in the bottom, for hard drives, standoffs, PCBs, and more, shown below. Over time, these penetrations are likely to introduce more dust and debris than the side vents of the recorder.
