vadimo 0 Posted February 28, 2011 I have about 12 x IK-WB15A installed. After 2 years i re-visited site and now see that most of the cameras have diffect: on inside of clear bubble plastic cover there is like a patch of smudge, its not dust! I noticed the patch is only where the lense and cut section seat in home position, i can only think that its the heat comming from the solid state components and exiting via lense cut section on to the bubble cover Problem i have is you cant take these cameras apart, 2 pcbs seat on top plus all the moving parts inside, i cant even twist the bubble. Anyone else has such problem? PS: they are powered using supplied PSUs not via PoE switch Thanks Share this post Link to post Share on other sites
