Sharp Ccd 540 Tvl

[Scott NCA]

Hello all what great forum this is!!

I need some input regarding some sharp 540tvl ccd chip camera’s i have installed in a retail shop. 14 have been fitted in total and the overall picture is ok but a cycle of yellow and white pulsing in the image is happening over a period of time. I have contacted the supplier and all they have said that its a result of the ambient fluorescent lighting, but surely this would flicker not pulse and get shadows? if some one has any input i would appreciate it or any views on the said chipset. I have a link to some footage with an internal player if some one can make any sense from it
