Since I had an old CCTV camera lying around, I decided to connect it to the LCD projector...
This is a very nice CCTV camera. But before I
can use it properly, I would have to change the
lens. And by jove, I do have another lens too!
This was the wrong lens I bought when I was
trying out some CCTV theories (from my own
pocket, of course). And now, its needed here.

First test, the camera is working. This model
does not have those IR LEDs which allows it
to see in the dark. Not that I need it as during
close up, they might compromise the image.

Sometimes, changing the lens is very simple
which involves unscrewing the lens itself. But
in some camera models, you would need a
small screwdriver to untighten a retaining
screw. Its a pain but this screw is important
in CCTV application as it makes sure the
lens are never out of focus when some very
clumsy oaf (like me) fiddles around with it.

After the lens change, I got a much better picture.
In actual fact, I do not need to change the lens
at all as the original lens was quite OK. but I just
want to make sure it can do close-ups. So, this is
as close I want it to be and after some focusing.
