Hello,

A few weeks ago I posted about using an IP camera as a baby monitor and
commented that it didn't do so well in low-light conditions.

Due to a fault with my ISPs news servers I've had to unsubscribe and re-
subscribe to all groups and I've lost all the posts.

Someone suggested that I place some IR LEDs in the room to improve
things in zero light. I would like to learn more about this but don't
have a vast amount of time, therefore can anyone tell me about it here
or point me to a web resource?

The camera is a linksys WVG54C. A supplier of LEDs might also help.

Thanks

Ebay's a good place for LEDs.

940nm and above is invisible so no red glow.

That should never be a problem.

An IF lamp will be a lot more use than an array of Leds.

OK I understand the principle of IR etc, but if I simply stick an array
of IR LEDs or an IR lamp in the room my camera will be able to "see" in
the dark then?

Is it really that simple?

sadly not. you'd at least have to wire em together in series/paralell and put
power through the circuit to get it to work ) but, yes, the camera will be able
to see whatever is in the room but it looks like a scene out of blair witch.

Black and white CCD cameras are very sensitive to IR light (colour CCDs
usually have IR-block filters in front of them).

This looks useful to you:

He can use a TV remote to get an idea of sensitivity.
Obviously a colour camara is only going to yeild a B&W (well monochrome to
be precise)
image.

Not always. Some (many) cameras have an IR filter over the back of the
lens or the front of the sensor. You can prise this off and then you'll
have really good IR sensetivity, but daylight images will look a bit
odd.

This sounds like a plan. SO I stick the camera in the room and turn all
the lights off, then point my sky remote at it and see how brightly it
lights up?

If I can see a white dot coming from my remote then an IR lamp or LED
array will "illuminate" my room in the dark?

Yes. But even those with IR filters can do that - it's just that if you
take the filter off it's much brighter.

That was me Have you seen those external CCTV cameras that plug into
your TV? They do a variant of that which consists of the camera element in
the centre and a ring of IR LEDs around the outside (about 8 of them I
recall), these seem to do the job quite well. Could cannibalise one of
those, but the quickest and easiest way is to get some IR LEDs from Ebay,
hook em up in parallel, put a current limiting resistor on the positive
side, then hook up to a suitable powersource (which you may be able to
parasite from the camera). Quick guide he

This module works well:

It's an Aussie firm but they do supply to the UK.
