Wildviews are junk.

I had the same problem with mine. I found out the sd cards in the wildview cameras need to be formatted. This helped but I'm not impressed with the wildview cameras.

I don't know if this will help but I called tech support on one of my camera's and I was told to always use the same card for the same camera. Call the cards 1A and 1B and switch them every other time.

I was also told always allow the camera to delete the pictures when placed back in the camera never delete on your computer. Not sure what this does?

Again not sure if this will help but something to think about.
