preferably out of glass. plus somehow in the process of removing and cleaning the other camera lenses I managed to lose the lense. anyone know where I can get a replacement lense?
Help this is my now fourth IPC-HFW5241E-Z12E with water intrusion through the lense. does anyone make a replacement lenses?

Maybe it's the time to replace its drier bag, the wet air inside when meet some cold wind or rain, inside will have condensation.
Also check the seal if still in good condtion.

our temps go from 72 at night 95 during the hot days, but the solar heat gain would be much higher than that. but it seems the seal at the lenses is failing.
also how are you getting the cameras apart to reach the desiccants bag?
is there an a newer model?

4 down one to go
@Dave Lonsdale advised @bradner successfully about the front cover on the sister 5231 in Dec. 2020 here ==>> Assistance with removing condensation from Dahua HFW5231E-Z12
are the factory lenses clear or yellow tinted? mine are yellowed and they are starting to get little defectives in them like they heat stress cracks. we rarely see temps into the mid 90's but the solar heat gain is high here
One thing I’ll note is you painted the housing black. That isn’t helping you or the hardware at all. I understand why you did that to run more stealth / blend in.
But, you’re not helping your cause or the hardware because it’s going to fail. Heat is the biggest contributor to short service life or failing electronics. Failures on a component level almost always impact capacitors as they dry out, expand, or explode.
Anything that generates heat like the power supply will also be impacted by the excessive heat.
If you see fogging of the internal lens and it’s not related to a sealing issue. It’s almost always due extreme temperature differential in combination with the amount of humidity inside vs outside.
Once you see persistent moisture inside this indicates the electronics are exposed to the same. The end result is corrosion causing higher resistance somewhere which translates to higher voltage / current draw.
Have all of that for an extended period of time.
Poof . . .

but yet the same lenses are used in their other cameras that you can order in black
Sure, but as you noted in your personal environment it gets hot. Everyone can relate to being outside and say it’s 90’F.
You go open the door to your vehicle that was sitting there baking in the sun?!? The interior is easily 120 - 150’F plus depending upon where you are in the world.
You take something that is in a very small confined space which by default generates its own heat?!? Whelps, things are going to fail prematurely or explode in an epic fashion.
Everyone who sees a black housing as it relates to a camera would just assume it’s designed and so rated to endure the extra heat!
One would think but in this day and age that common sense aspect has been lost on people.
In the past you would be very hard pressed to ever lay eyes on any camera that wasn’t a shade / hue of white.Today you do see a few but I can assure you extremely few of these companies changed anything to allow said (black) camera to operate with the higher temperatures.

I’ve had 2 do this over the years. Both were 52xx series… I replaced one after it died completely and I upgraded the other. But both started with moisture under the exterior plastic cover. As it faced the west sun the cover became yellowed and cracked and I was able to swap it with the good cover from the one that died. It held up until I upgraded it.
The one I upgraded with is a 5241 Z12 I’ve had up for about a year and a half with no issues yet.
95 degrees and 90%+ humidity is normal here. As are torrential daily storms and the occasional hurricane. It seems the problem as noted comes from quick temp differential.

I have noticed that the silicone caulk that is put in around that lenses cover is not cured all the way through and is still gummy even after about a year in our Florida weather.
but since the Dahua offers that same camera in black and surely their engineers have seen sunshine before

I took mine apart and replaced the desiccant bags (bought some from Amazon) but the camera never came back on-line unfortunately. I gave up on that model. It wasn't too bad taking it apart but I think there's a design flaw.

What you did with it? I could take it apart and study it a bit, maybe we can learn from it.

You could try mounting a plate over it so it sits in the shade, That will help reduce the temperatures, shield it from rain and if it overhangs the front (recommended) will also shade the lens and reduce reflections. Not going to say it's a fix, but it should at least help if not a cure. Also note the comments on colour. White reflects heat, black absorbs heat so black will definately be raising the temperature of your camera considerably if in full sun.
