All photography and video is based on
light. The less the light the poorer
quality and more grainy. The low light
cameras are B&W so that they don't need as
much light. If you are monitoring for
safety reasons you will not normally need
colour or broadcast quality video.
If you have a lamp on in the room, you can
put an X-10 module on it, and then use the
built in dimming function to set the light
intensity as you need it while looking at
the monitor. The audio will be very
important.
You could even put a motion detector
directed at the child, and a remote chime
to indicate when there is movement if you
so desire. Lots of options ... and
certainly one is to spend a lot more money
on an infra-red solution. All infra-red
photos and video are black and white as
well ...
And as most people know babies sleep in the
daytime too. Some people don't realize the
purpose of eyelids. I don't know anyone
who puts a baby in a totally dark room at
night. They usually keep enough light to
walk in and check on the baby, which would
certainly be enough for a low light camera.
