That makes sense, I reviewed the footage and it doesn’t look like a thermal camera. I read this one of the YouTube comments:

“Professional photographer here. That was not a thermal imaging camera. That was a canon 1DX camera. A popular photography and video camera. The big thing around it was a camera stabilizer gimbal, most likely a Movi M5. That set up is used for filming high-end videos and commercials, sometimes TV shows. A police department would not have a set up like that. I use set ups like this to film car commercials. That was not a thermal imaging camera.”

maybe you missed the part where Fresno PD pulled up to his house with a vehicle mounted thermal imaging device (its in the photos and last video) to see through his walls to make sure he wasn’t home.
