basilb Posted May 20, 2011 Posted May 20, 2011 Some cameras I installed a couple years ago have problems now with IR whiteout at night caused by the acrylic covers getting scuffed from wear & tear. They have the IR inside the dome around the lens. It doesn't seem to take much to get micro scratches in the plastic - I assume from cleaning &/or wind borne dirt. Is this a common problem & should I have stayed away from in-built IR?
Oxford Posted May 20, 2011 Posted May 20, 2011 I believe this is a problem, I have some Vista cameras at home and they have done the same.
Driller Posted May 21, 2011 Posted May 21, 2011 Can you not just replace the covers, are spares available?
Cubit Posted May 21, 2011 Posted May 21, 2011 Can you not just replace the covers, are spares available? more commonly, the seal between lens and cover fails/shrinks/distorts etc. This allows the IR reflections into the lens thus giving the white out.
satsuma01 Posted May 21, 2011 Posted May 21, 2011 the dome camera that looks over my koi/stergeon pond came with IR inbuilt into it but i unplugged the lead to the ir bit so ir doesnt work as like others have said it had a white ring round the lens which made video picture look terrible at night, luckily tho with the pond brick lights lit up during the night the irs arnt needed but i tried it and didnt think much of it at the time, imho its better to have a seperate ir lamp fixed to the building along side each camera "If you carry your childhood with you, you never become old.

IAS Posted May 21, 2011 Posted May 21, 2011 yes it`s a common problem but a couple of years ago LED`S were the answer to everything, today it`s "sens up" technology ................. tomorrow it`ll be something else. its always a compromise.
