    Dahua 2017 International Product Catalog (Q1)

    The 2MP 1/1.9 is better than the 3MP 1/2.8. But it is not so much better. It is not as simple as 1/1.9" vs 1/2.8". The 1/1.9" is the old non-starvis IMX185. The 1/2.8" is the much newer starvis IMX123.

    Dahua Ultra 2mp Starlight, 6mp or 12mp camera?

    It does not only depend on the sensor size. As I have said many times, the technique used in the sensor is just as important. The 1/1.9" 2MP sensor is a normal Exmor sensor. It is very good but old. The 1/1.8" 6MP sensor is a modern back-illuminated Exmor-R sensor. This technique is much more...

    Dahua Ultra Starlight Varifocal Bullet (IPC-HFW8232E-Z)

    Hi Nayr, very nice. I'm looking forward to see your review. But such a sensor doesn't exist. It is the Sony IMX185 and this is not a starvis-sensor. ;-)

    Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)

    Please distinguish sensor and camera. Dahua don't call this cams Starlight, thats right. The sensor itself is in the Sony starvis line, like the IMX291: The IMX291 has a back-illuminated structure with 2.9 µm-square unit pixel, the IMX178 has a back-illuminated structure with 2.4 µm-square...

    IPC-HFW8232E-Z Sensor Type?

    According to the tech spec the HFW8232 is little bit better, 0.002Lux vs. 0.005Lux. But, please buy the new HFW8231, because I'm very interested in the DOL-WDR. ;)

    IPC-HFW8232E-Z Sensor Type?

    HFW8232 uses an old but bigger Exmor (should be IMX185) HFW8231 uses an new but smaller Exmor-R (should be IMX290) HFW8231 is Dahuas Ultra-WDR cam (140db) could be sonys DOL-WDR-function of the IMX290.
