HIKVISION DS-2CE56H1T-ITM - DS-7204HUHI-F1/S - Ghosting

[Alan Walker]

Good Afternoon,

I wonder if you could advise me please.. The picture is great, good quality, but if you have a building with the light behind it, you get ghosting from the building

Can you advise what needs to be changed please…


All the best from Alan

Hi Alan,
I don't think that ghosting is caused by the backlight / sky.
I guess you'll see a similar effect if you point the camera at something else, in the other direction.

I'd checkout / rule-out / replace the co-ax cable and BNC connections first.
See if you can get the camera on a short cable, or better still a factory-made cable and see if you get the same effect.

Good Evening Phil,
You are quite right, it does not matter where I point it there is always shadow/ghosting
tomorrow I will go to Maplins and get a shorter cable.

It is on a standard 20meter cable, 3m thick wire.

I will let you know how I got on...

Thanks again

All the best from Alan

Good Afternoon Phil,
I disconnected the Video cable and put 50ohm coax in place 5 meters, and it is perfect..

That leaves the final question, where can I buy decent cables from

All the best and thank you from Alan
