Great low light cam...,
Verified Purchase(What's this?)
This review is from: Foscam FI9831W 1.3 Megapixel (1280x960p) H.264 Wireless/Wired Pan/Tilt IP Camera with IR-Cut Filter - 26ft Night Vision and 2.8mm Lens (70° Viewing Angle) - White (Electronics)
Though the 9831 surpasses the 9821 in low and night lighting, the 9821 maintains a better balanced lighting perspective overall. With the 9831, I see significant amounts of chromatic aberrations from any sun-lit source in the background of the main image, such as anything beyond a window. However, with the 9821, you can view the main space, and the space beyond the windows, out to the outdoors.
This would be a fantastic camera for low light situations primarily, The image quality is high, but the normal light performance can be problematic. Perhaps I just got a fluke, though I still like the camera, if on sale.
