RE: low light cameras with IR LED's

["Malcolm Surgenor" <malcolm@xxxxxxx>]

I notice the LL20 goes down to 0.003 Lux at F2.0 and has an Ex-view CCD
where as the CC50CH only goes down to 0.5 Lux at F2.0 w/o LED.  Both claim
to go to 0 Lux with LED.  So I guess the LL20 has a head start.  :-)

Yes - just found that out too - I tried walking up to it and was
illuminated. My older LL20's gave a much brighter image though (must just
be
much more sensitive)
