Hello All, I have the Dahua IPC-HFW5231E-Z5 which I purchased from Andy, Empire Technology less than a year ago. We've had solid rain in our area for 3 days straight. I noticed there's water inside the lens. It's causing the image to be blurry and I can no longer read license plate. Is this normal? I emailed Andy and he says this is normal and he suggested that I take it apart and seal it better. I thought this is at least IP66 rated? What happened? Thank you.
