New Cam 2C pro not working in color during the night

Just bought a Cam 2C pro to add to my additional 2 standrard Cam 2C units. I’m noticing when I turn on the Cam 2C pro to view the video it, the video stays in color for about 2 seconds and then automatically switches to black and white. I’ve notice this happens at night when its darks. My original Cam 2C cameras do no do this. They stay color when I view the video. I’m wondering if there is something wrong with the Cam 2C pro camera I just got?

Spotlight turned on?
