(In fairness, the WyzeCam costs ~$20 to replace, so it might be seen as semi-disposable for many.)
But most indoor cameras cost more than $20, often hundreds. And even indirect water damage, freeze/thaw, or dust and mold can seriously damage cameras. Warranties for 'indoor-only' equipment typically are voided when the problem is traced back to outdoor installations.
One of the most common reasons 'indoor-only' ratings are ignored is because the outdoor versions cost more or are not available (as is the case with WyzeCam).
When you sell/install equipment, how rigid do you use only outdoor-rated gear outside versus risk damage or premature failure?
Okay - I'll admit it. We used some indoor Mobotix cameras for a couple short-term projects and they've worked fine - In fact, they are still in our inventory for temp jobs and still get used from time-to-time. As long as they aren't getting hit with direct rain or runoff, they've performed well. This would not be something we'd do for a client on a permanent install basis though. These are part of our own internal stock. When we get them back and clean them up, we can see the evidence of dirt/grim making their way into the camera internal areas through the ventilation holes/factory seams, etc. I would imagine that long term exposure to even temporary humid environments would eventually corrode the circuit boards and kill them off if we weren't periodically servicing them as they cycle through our inventory. Also, we prep the network jacks with a dielectric gel/grease to help prevent corrosion at those junction points - And actually do that on all our exterior installs. When we clean the circuit boards, we use ACF-50 or CorrosionX Aviation sprays for anti-corrosion.
