Can anybody explain the blue tint that I get at certain times of the day? Is it the camera or the NVR that's causing this?

Natural Color - No Direct Sun (cropped image)



Blue Tinted - Sun Hitting Camera (cropped image)



The reason I asked is because I just replaced my SWANN NVR8-7200 with a HIKVISION DS-7608NI-I2/8P. The SWANN had a 2MP NHD-820 camera (aka DS-2CD2022-I), whereas the HIKVISION has a 4MP DS-2CD2042-I. The SWANN camera never behaved that way. Also, I did not change the monitor, only the NVR and cameras.

I hope I can correct this blue tint somehow.

Wide dynamic range or head light compensation. Dahua has hlc but i think thats more for night time use. Not sure if Hik has it.

I would log into the camera and see what kind of settings you have.

@GH75, I'm still not following you. I'm a newbie, so please be patient.

Are you saying that the WDR should be turned off/on, or that the values are wrong. If values, what's the recommended? HIKVISION doesn't have HIC as far as I know.

Its ok. I really dont know if any of that will help. Just making some suggestions.

This weekend at that time of day, log into the camera and make some adjustments. One at a time and you should see the result instantly.

WDR may not help but it takes 60 seconds to try. Try it off and on. I do not think there is a value, just off and on.

I am not familiar with HIK. It may just be the way the camera works....

I modified the white balance and that corrected the blue tint problem. It still shows up a little at dusk (on the house only), but not during the rest of the day like before.
Thanks again @nayer for your advice.
