By: Ethan Ace, Published on Jul 02, 2018

Based on member 4MP testing requests, we bought and tested Digital Watchdog's low-cost 4MP DWC-MTT4Wi to see how it performs in real world scenes, examining key features, including:

  • Full light performance
  • Low light performance
  • Integrated IR coverage
  • Integrated IR range
  • WDR performance
  • Bandwidth consumption
  • Physical construction

This is the latest in our updated 4MP entry level testing. Readers should also see our test of the Hanwha QNV-7010R and watch for upcoming tests of new Hikvision, Dahua, Uniview, and others this summer.
