Perhaps this has been addressed previously, my apologies if it has...
I operate 3 of these cams at a remote location. I find that when the Day/Night Mode is set to Auto, the switchover between modes always triggers a flood of emails (via Motion Detection). I've tried rolling back the sensitivity, but the only solution is to set the cameras all to full time night mode. This means that in sunlight, the images are quite washed out.
I would like to see the firmware improved to include something like a 20 second suspension in motion detection when the Day/Night mode is switching over. This would give the camera time to stabilize the image before the motion detection kicked back on.
