What's with the pink picture?!

Hard to tell exactly what is causing the pink picture, but I believe it may be a malfunction of the camera possibly due to extreme cold. Temperatures over the holiday weekend were frigid and on Tuesday morning, the picture was pink. This same scenario played out in early December with extremely cold conditions then. The pink has only occurred with the nestbox camera image--the ledgecam so far is unaffected. Luckily, simply unplugging the camera seems to put the settings back to normal. We'll continue to monitor the situation!
