Title: DCS-9XX - Fix for Visual Artifacts [Hardware Modification]
Post by: JavaLawyer on January 15, 2013, 12:45:43 PM
This procedure is designed to fix visual artifacts (e.g. horizontal lines) under low/no light conditions reported by multiple owners of DCS-930, DCS-930L, and DCS-932L cameras. The suspected cause is the omission of noise filtering of the CMOS signal under low light conditions. These image artifacts have resulted in reports of false positive motion detection events. This procedure involves opening the DCS-9XX case and soldering a capacitor on the camera. This procedure is a DIY hardware modification not supported or sanctioned by D-Link.
