Getting the hang of it
Can you use both starlight and IR in the same area with no problem. It would be the IR camera crossing the starlight camera some 10 yards in front of it.
Heck, I am still waiting for the 1/1.2" sensor to make it's way into a vari-focal camera, and that sensor has been out for a while now.Cameras that are sensitive to IR light generally have an electro-mechanical IR cut filter that activates when in night mode and operate in greyscale at night. You can force a camera to stay in color mode but without enough light it may not see too well.
There are no issues mixing cameras that are in color mode and ir mode other than potentially seeing a bit of purplish light from ir emitters.
Most 'starlight' cameras can operate in IR mode, so your question is a bit confusing. At some point we may see security cameras that operate in a combined color + ir mode made possible by 4 channel image sensors (RGB+IR), these sensors have been out a while but few have made it into cameras
