I have nowhere else to turn so I thought I'd give this a shot.


I have a camera almost identical to your PTZ-LX700IR250L27X


Over the past year it has gotten some small fog spots on the inside dome face- the area that's over the lens itself. Turning on the fans manually in the camera does not clear it. It really needs to be wiped clean at this point. Is there any way at all that you know of to remove the clear face of this camera to clean the inside of it? I see the lens portion has a gasket type ring on the outside of the face. Do you know if this can be removed and then put back in place? I just want to wipe clean the inside of the clear face of this camera but I don't have a clue how or if it can be done. 


Thank you for any suggestions or help. I really appreciate it.

If it was our camera I would say lets get an RMA for it as I really would not want you opening the camera and voiding the warranty.  If you take the lens off you risk damaging the seal and it will leak for sure. Possibly getting some silicon packets inside the camera may fix the issue. (NOT RICE) The appearance of fog after months of usage tells me a seal may be bad or it is not venting correctly. See if that camera has a vent it may be dirty. If the camera is still under warranty I would send it back. If it is not under warranty then I would open it since its not like you are going to void the warranty. The issue you are most likely to have if you take it apart is re-assembly with old seals. A dab of silicone can go a long way to make sure the seals don't leak.

Thanks for you replies. This got the worst last year when our power was off for three days after hurricane sandy. I can turn the fans on manually, but it doesn't clear it. The heat fans maybe could, but I can't turn that on manually. They come on when it gets colder out and that won't be for a while. It may well be a dry pack that's done in there and any fan is just circulating that moist air now. I see the bottom portion can be removed to get to the boards. Perhaps there's a dry pack in there I can replace. But the face itself looks like it doesn't come off and I would really like to clean the inside part that's over the lens itself. Perhaps even clean the lens while I'm at it. I really think the fog rings are residue at this point that needs to actually be wiped clean. It's interesting because it states that a number of different camera modules can work in this dome, suggesting you can swap out the camera itself for something else, or if the camera dies. But the dome itself looks to be completely sealed with no way to open it properly. It's out of warranty now too. I'll try and post a pic, but the ball dome portion just has a seam around it and the back. There's no obvious way to open it. I even thought maybe the black lens ring on the outer face might pop off or unscrew, but I haven't messed with it. Thanks a bunch for your help. You guys are great to extend and hand even though this isn't your camera. That only inspires me more to make a purchase of some product from you soon! Thanks again.

I was able to get the clear dome face off. It's just a snap on, but you have to get the separation in the seam started and work your way around the seam and it comes off. There was a nasty film buildup on the inside part that goes over the lens. I wiped that clean and used a lens cloth to wipe the lens itself clean and reinstalled the cover. It's like I did cataract surgery on the ptz- it looks better than new!  I have been keeping a close eye on it and so far, the buildup has not come back. But it's nice to know that if I have to, I can do it again. This is also the only way to swap out the camera if needed, so getting the dome face off on this style camera is doable. I did not put dry packs in this time. I want to see if this reoccurs before doing that. I chose a low humidity day to do this, and I wasted no time getting the cover back in place. For anyone with a SCK ptz, you at least have the proper resource for support if needed. This may never happen to yours. It really shouldn't happen in the first place. Always call support to work through an issue if needed.
