image cropped on lower resolution

[kcinick]

image in 2560x1920

image in 1920x1080

is there a way to use the 1920x1080 resolution but without cropping, i wanna see the whole picture, i don't care about stretching if there is any...

Hi kcinick,

What camera is this, and what resolutions are available?

2048x1536
2560x1920

DS-2CD2155F-IS

1280x720
1920x1080
2048x1536
2560x1920

How does the 1280x720 image compare?

 

[kcinick]

just like the 1920x1080

 

[mat200]

just like the 1920x1080

Just like the crop on as the 1920x1080 OR less? ( that is even more cropped )

 

[kcinick]

the same

I think some cameras have configurable scaling methods, but for others the developers were lazy and don't provide an option, or maybe the chipset they used can't handle some kinds of scaling. Some of my old junky Chinese cams did this forced cropping thing, but I haven't known HIkvision to do it too

could be a solution changing the lens for a 1.8mm or something like that?

If you can find a lens that fits and is sufficiently high quality for a multi-megapixel camera with IR, that could be an option. It looks like that camera uses a standard M12 lens but that is no guarantee of a good fit, and there are certainly some M12 lenses that wouldn't fit under the dome or wouldn't be able to focus properly without physically contacting the sensor housing.

2560x1920 is 4:3 format, and 1920x1080 is 16:9 format (wide screen).

So 1920x1080 will just crop part of the top/bottom from the sensor to show you a wide screen image.

Yes, they could just provide a way/setting to adjust this, so it would still use all the sensor and then the 1920x1080 would just look stretched. But they don't

If you look at his screenshots though, they have cropped it on all sides, not just top and bottom!
