Dahua Night Color 2.0 "Fusion" Camera Tested
While cameras including both monochrome and color imagers are rare, the Dahua N45DUD2 claims to provide "full-color images in poorly lit scenes", but how well does it actually perform?
IPVM bought and tested the Dahua N45DUD2 Night Color Camera and compared it to Hikvision 2347, Hanwha ANV-7012, and the Wyze v3 Pro, and in this report, we examine:
