The D-link DCS-3420 takes the usability attributes of the D-Link DCS-1110 and piles plenty of extra functionality on top, starting with 802.11b/g (WEP and WPA security included), moving from support for four cameras to up to 16, and accommodating interchangeable lenses (chief among them the optional infrared unit for shooting in total darkness). We didn’t receive the IR or auto iris lenses for testing, and our unit seemed biased by default for shooting in low light as images were very over-exposed.
However, altering the video settings for optimal balance between bit rate, frame rate, and quality and tweaking the image settings (brightness, hue, etc.) yielded substantially better results. Even with the stock lens, though, low-light video proved remarkably clear.
