Dahua "Stronger AI, Better Image" AI Self Scene Adaptation Camera Tested
Dahua claims its AI Scene Self-Adaptation cameras use "stronger AI" for "better image", but how well does AI SSA actually perform?
IPVM bought and tested the Dahua N53CL62 AI SSA camera and compared it to Axis M2036-LE, and the Hanwha ANV-7012, and in this report, we examine:
- How does the AI SSA perform in strong backlight and flicker scenes?
- How does this camera perform in WDR scenes?
- How does image quality compare in full light, low light (~5 lux and ~1 lux), and dark (<.1 lux) scenes to the Axis M2036 and Hanwha ANV-7012?
- How does bandwidth compare in day and night scenes?
- How well does the camera integrate into third-party VMSes, including Avigilon Control Center, Exacqvision, Genetec, and NXWitness?
