Hi all,

I do have the problem that there is moisture in my Dahua IPC-HDW2231R-ZS which makes it hard for me to have a clear picture.
Is there a way to solve this?
Should I open the camera?

Thanks for your help in advance.

You will need to take it down, open it up in a dry (low humidity) environment and get it dried out. There should be a packet or two of desiccant inside and they may need to be replaced. Take a good look at the rubber seal and make sure it was seated properly. A little bit of petroleum jelly on the gasket will help seal it.

I had this problem on one camera that would get rain directly on the can. It has the desiccants and the rubber seal but fogged anyway. Ultimately I ran a ring of electrical tape around the two halves of the housing and that has fixed it. Luckily I had white electrical tape so you don't even notice it.

Hello bruce the boss, unfortunately the camera will have to undergo surgery to fix the issue.

It'll need the guts removing and a good look over to see exactly where Water has entered the camera and it will also need the optics to be cleaned as well (a basic clean will make images more clear).

Replacement Silica gel packs will be needed as they'll have absorbed as much water as they're able.

Not too sure on the suitability of petroleum jelly with the gasket, probably best to find a suitable silicone safe grease or at worst you may need to use a silicone sealant (that's if you've got a bad leaking issue that really needs to be fixed).

And I forgot to mention that if you have access to an Air Dryer it would really help to remove moisture quickly without damaging the housing, optics, cabling and electronics. As they can achieve a constant 40°C.

Hope that you get it sorted out though and good luck.

Make certain the cable entrance to the cam is sealed as well. Maybe a dab of silicone.
When getting a new camera, always check all screws to make sure they are snug, I've had some that the screws could easily be turned another 2-3 rounds.

Also, if you notice that rain droplets are falling directly onto the camera itself, you might want to consider adding an "umbrella" to the camera

Recently had to do this for a IPC-HFW5231E-Z12. Take part was easy once I learned the THIN plastic surround at the front peals off.

Two hours at 158F in my 3D filament dryer (a repurposed food dehydrator) got the camera thoroughly dried.
New silica packs and a bit of silicone dive grease on the gaskets later, she was back in action.

BTW 158F metal housings are pretty hot for bare hands. Be careful taking back out of dehydrator if you use one to dry a camera.

A company called Haenim do UV sterilizers with a drying function, very expensive but also very useful.

The Haenim HN-04 is the latest version with Bluetooth so that you can know exactly how long is left in a cycle.
