Why the video is red (pink) tinted? How to fix it?

No worries about the red (pink) tinted picture. This is caused by the PIR sensor when SENS8 was initially set up. It should adjust itself later or you can manually adjust it by following the instructions below.

You can fix it by covering the top of the device with your hand for a few seconds till the video turns into night vision (black and white picture), then check it again.
