Why is my video feed displaying only black and white?

If the image displayed is always black and white, the night vision might be auto enabled in settings, the LED's might be unclean or not working properly. First, plug your camera into a computer to install Dropcam's software to access its settings. In settings, you will find an option for disabling or enabling night vision. Make sure that this is set to "Auto." If this does not fix your issue, you can follow the guides on the troubleshooting page to fix or clean the LEDs.

I have 4 camera only on is in black and white why.
