Datasheet

This weatherproof camera module comes in a nice metal case with a
mounting hinge, a 1 meter long cable with the TTL & NTSC signals
brought out, and it has an automatic IR LED system for night time
photos. When the on-board photocell detects that it is too dark for the
camera to take a photo, it turns on a ring of 12 IR LEDs that illuminate
the nearby area for night-vision shots.
This camera was designed to be used in security systems and does two
main things - it outputs NTSC video and can take snapshots of that
video and transmit them over the TTL serial link. You can snap pictures
at 640x480, 320x240 or 160x120 and they're pre-compressed JPEG
images which makes them nice and small and easy to store on an SD
card. Perfect for a data-logging, security, or photography project.
One nice thing about this particular camera is all the 'extras' that come
with it. For example it has manually adjustable focus, auto-white-
balance, auto-brightness and auto-contrast taken care of for you as
well as motion detection built in! That means you can have it alert your
project when something moved in the frame.
