One of the Tactacams finally sent some pictures.
It’s normally warmer right beside the river but not today.
There's a setting on my Tactacam that sends a daily pic just to verify it is working properly. I use it on one particular camera that is there for security and thankfully has very little activity.
Finally had the last camera thaw out at 3:50 this afternoon, and they’re all sending pictures again.

Inside moisture? I had another camera “fog up” from inside moisture. I pulled the battery pak, SD card, SIM card and removed antenna, thereby exposing all orifices. I then laid a vacuum hose in close proximity of the SD port and let it suck air thru the camera for several minutes. Worked great and cleared it right up and has stayed that way. Helped that the house humidity was very low when I did it.
I strongly suspect it was just frost on the outside, because it cleared up on every camera as the sun came out and got warmer.
There’s nothing I could do about it from 500 miles away anyway.
