はじめに

The WiLife Outdoor Camera has a high failure rate, often malfunctioning after the warranty expires. Four faulty capacitors are the most common cause of failure.

This guide is based on the work of Steven Markham

Background

The WiLife Security Camera System was developed and sold by WiLife, Inc. This system was originally called LukWerks. Wilife was acquired by Logitech Corp in November 2007. The system name was changed to WiLife. In September 2010, Logitech discontinued support and production of the WiLife Security Camera System.
