Re: How to "Infrared Enable" a normal CCTV camera

["Tim Fletcher" <timfletcher@xxxxxxx>]

Be sure to check the spectral response of the sensor.  Although many
sensors are sensitive into the IR (850nm+) manufacturers often put an IR
Block filter onto the sensor bundle - sometimes this is removable, so check
first.  An easy check is to use a TV remote - if you can see the LEDs you
should be ok!!!

Cheers,

Tim.

Hi everyone,

has anyone converted his cctv camera to an infrared-enabled one? I have
lots of those small pinhole ones and after the sun sets they are crap. I
presume that building an array of infrared leds (850-880nm) would do the
trick. However they are a bit expensive (0.50 pounds each) so building a
big array of them is not really worth the risk at least before asking
first.

So, any ideas or sources of information?

Thanks,
Thanos

I know that a few people on this group have a Rotozip for various bits of
work. These appear not to be available in the UK any more. I am about to
order a number of accessories and spare parts from the US from
www.homelumbercom.com. If anyone else requires anything, please contact me
off list and I sure we can add bits and bobs to the order. For small items
like drill bits I would only be looking to get the UK postage costs
covered,
however if you want something a bit bigger (I'm getting the large hole
cutter) then a portion the US shipping costs would be added. I assume that
we will get clobbered for VAT/import tax at some point as well.
