Two months ago Dahua released TIOC-PRO cams (3449H-AS-PV-PRO), which for first time in lower WizSense line had a bigger 1/1.8” image sensor with 4/6/8 Mpx resolutions. I had installed 6 pcs of 4Mpx turret variant and must say that night performance is very good, better that 5442 in very low light situations.
This is mostly due a new image sensors, the same which HIK is using in his ColorVU 2.0 cams. A new image sensor in 3449-PRO generates several times less noise comparing to very noisy sensor used in 5442/5842. I tested both at total darkness with very short exposure time (1/250 - 1/1000) and difference in noise is huge.
A few days ago Dahua teased on website and YouTube a new WizColor cameras category, which will be using big 1/1.8” sensor, open aperture F1.0 and a new AI powered Image processor. Today We can find a product pages for those new models called 2449-PRO:
For first time we see information what AI-ISP really means. Looks like 2D and 3D noise reduction algorithm were replaced by AI trained networks.
“The AI-ISP technology also incorporates a deep learning image processing algorithm with 3-layer temporal noise reduction, 2-layer 2D noise reduction, and precise motion detection” Bai said. “These advancements result in a significant upgrade to the denoising module, offering a 50% improvement in scene detail restoration, a 30% enhancement in color accuracy, a 200% increase in motion detection precision, and an 80% reduction in motion blur.”
Interesting is that a new TIOC-PRO (3449-PRO / 3649-PRO / 3849-PRO, Color4M in Andy shop) are also included in this new WizColor category. Models on actual firmware don’t have performance We see on Youtube demonstration but it looks that AI processing will be enabled in a new firmware.
Dahua announces a new OTA upgrade in October - probably which will activate WizColor / AI-ISP functionality.
