Wally,
Seems many people prefer their cameras stay in the Day Mode (a much better-quality video picture than Night Mode), when there is plenty of external lighting available.
But currently only the camera decides (when it gets dark) when to switch from Day to Night Mode, and many people want to be able to decide if they want to stay in Day Mode, regardless of the time of day …
The black glassy-portion of the cam (where the Blue LED can be seen when the camera is active) there are several items hidden behind this smokey plastic, which include the motion sensors and a light-sensing photocell. When there is plenty of light, determined by the photocell (in Day Mode) your camera displays in color. When the photocell does not sense a sufficient amount of light, currently the camera decides on its own to go into Night Mode, and hence the black & white IR video is displayed. You cannot control when it switches between Day or Night Modes. If the cam viewing area is already bright enough, it is possible the cam will remain in Day Mode all night long. Also, if the cam is already in Night Mode in a fairly well-lit area, when the cam’s spotlight activates this additive light might be enough for the photocell to decide to switch to the Day Mode. But currently this all depends on whether the photocell ‘sees’ enough light and how quickly it reacts to switch to Day Mode.
I hope this helps you.
