During the past five years I purchased 11 cameras to cover the perimeter of my house, but in the last three months two of the cameras (a HDBW4231F-E2-M and a HDBW4231E-ASE ) have died. I contacted Andy who said that these cameras have a useful life of 5-6 years, which makes the demise of my two cameras statistically understandable, but implies a terrible reliability. I searched the forum and could not find many complaints about cameras dying, so I'm wondering whether any of you have witnessed cameras failing close to the 5-year mark, or I simply have horrible luck.
