Q: The Logitech Wilife outdoor cameras have a known defect (caps melting).[...]They fail in about a year. This is due to the following four 1000uF caps: C26 C27 C31 C32. The initial was a10v cap then later releases were 16v. I replaced them with 25v. See Digikey part number UHE1E102MHD6. The caps are from Nichicon and are Aluminum Electrolytic. They are rated for 10,000 hours at 105 degrees C. The caps don't fit perfectly (the original are 8mm diameter versus 12.5mm that I put in) so insulate the leads and let them float above the circuit board.DLC-810e, CLC-110e, DLC810e, CLC110e, Lukwerks Outdoor Camera, 961-00290, Wilife Outdoor Camera, Logitech Outdoor Camera
