I was adjusting one of my 54IRs today and notice the outside of the camera ball felt pretty hot. I got my thermal heat measuring gun and it showed the temperature to be 127°. Is that within the range? Thanks

Since these temps aren't an issue, it seems that they may serve a good purpose by mitigating moisture?

No; it causes the opposite to happen: High temps cause the internal desiccant packs inside the camera to release the moisture they previously captured back into the air inside the camera, which then condenses on the clear window in front of the lens if the temperature suddenly drops. Typical scenario: Hot day, clouds and rain roll in, camera suddenly fogs up. Heat doesn't make moisture "go away", it just raises its dew point. This is why turning the A/C on in your car is far more effective at clearing condensation from your windshield than turning the heat on high. The cold condenser coil causes the moisture to condense out of the air, where it then drips out onto the road, leaving the air actually dry, causing it to quickly absorb the moisture from your windshield as it blows past. All the heater can do is raise the dew point and cause the moisture to slowly evaporate from your windshield back into the air.

I've had to take apart about a dozen of these cameras and replace the desiccant packs because the camera started fogging up—the cause almost always was clearly an incorrectly assembled camera (either the body or SD card cover screws weren't properly tightened down, or one of the seals wasn't properly seated). I now manually tighten all camera screws prior to installing to try to reduce the chance of this happening. In fact, I've got one camera in right now with that problem.

Wild, I live in Houston which is probably the most humid place on the planet, and I've not had 1 mess up
