ADT installed 3 security cameras around the perimeter of my building that do not work in the dark - they're useless at night! The salesman only listed color cameras on my contract and made no claim that they would operate at night or without a great deal of illumination.
I have lighting on the outside of my building, but nothing to the degree that these cameras need to capture a clear picture. On top of what I have already paid, ADT is quoting me $175 per camera to upgrade to a model intended to work in no light - low light conditions
