Live by all means, I was just thinking a minimal / minimised icon when the video starts / joins etc... I like the microscope idea.
Don't forget too that budget web cams can make cool night vision cameras: the cheaper and junkier the camera the better as they fall to bits faster
Once the chimp of Ird filter glass is biffed out then the CCD is typically very sensitive to a very small amount of Ird. I have found a single 'smokey' Ird LED emitter is enough for detecting Penguins in the cooler...
In the photo below you will see one setup with 4x Ird LED in series. This works out at almost exactly 5 volts raw off the USB port as 4x Ird LED's happen to draw exactly 30 to 50mA with no current limit resistor and really light up the scene.
Okay... so next stop motion detection > trigger > capture etc ?
