Uhggg....I'm getting definite focus blur after the camera has warmed up. The camera does not even have to be exposed to direct sunlight. The video softens like a soft filter has been put on it. This happens with a CPL either on or off, also, with the camera either in or out of the car (not pointing through a windshield. I have a handheld surface temp reader, the outside of the camera casing will go from ambient 50 degrees in the morning, and after I have driven for awhile the case will reach around 100 degrees F without direct sunlight. Perhaps the case is not vented enough? Here are two screen grabs at a gas station. the 'Hot" one is when I pulled in and parked in the shade. Notice the palm leaves and the details on the building. Now the "cool" or cool down camera just 12 to 15 minutes later. Nothing else has changed but temp. See the difference? this is frustrating, as I have had this issue with Guardian in past. Note: my Viofo 119S ver 2 never displayed this issue. Its a major focus issue for me
