FYI for the folks using trail cameras for hunting, game watching or security. Just bought a Primos Easy Cam for under $50 and really like the simplicity setting it up.
Drop in a blank SD card in the camera, turn it on for a minute or so while it installs date/time software, turn it off and remove the SD card. When you put the SD card in your computer the date/time software copies the date and time from your PC!
Then put the card back in the trail cam and turn on..that's it. Very compact also, no video - images only. Really a neat little camera and pictures look great with time/date displayed.
