Anyway to improve image

Getting the hang of it

Cameras are HDW2231R-Z. Current setting for night profile is Shutter priority at 0-8ms (1/125) and 3DNR is at 30. I have tried 3DNR at 15 it is more noise on the image. It seems like 20-30 give less noise but I like to see if there is any setting I can improve the image.

Lights on garage exterior are 75W, 5000K led. Street light also white LED. Would changing 75W to 100W light help?

@master_tinkerer Couple minutes to change the light. The bulb right now is 800 lumens. I can try to get the light out of view.

@tangent I more prefer color as the surrounding are pretty well lit. But I won't rule out your suggestion. Thanks.

Yes, I agree, both cams are staring at your lights. Need to move them over a bit to get them out of FOV. The pics actually don't look too bad, but if your complaint is getting good facial recognition, you need to zoom the cams in to the area of interest (cars). It is all about pixels on target.
 
A little bit more zoom and a little bit more light. These are with 1200 lumen/100W bulbs

I think the only substantial improvement you can get is to zoom the cameras in.
 
I suggest adding one IPC-HFW4239T-ASE for capturing color. It has a bigger lens allowing it to collect more light which results in a brighter picture.



Then the other cams can be put in IR mode and zoomed in and you will still have one cam doing color at a wide angle.

Also, an 8 ms maximum exposure might not be necessary for capturing foot traffic. I'd consider testing at 8ms and 16ms to see if the image quality at 16ms improves enough to outweigh the additional motion blur.

Brighter lights would not hurt either, but you can only go so far with visible light before your neighbors would start considering it offensive... lol. Certianly I'd upgrade the bulbs. It probably wouldn't be unreasonable to go with 2000-4000 lumen bulbs if you can fit them (they are quite large). I've had good luck with this brand: https://amazon.com/s/ref=nb_sb_noss_2?url=search-alias=aps&field-keywords=SANSI+LED

Thanks for the amazon link on the bulb.
I put 1 cam on IR and the other in color, also zoom in a bit on both. Will test out brighter light and 16ms exposure.

Comparing the post #1 to #17, I don't see any substantive improvement in the color images.

With that considerable amount of ambient light, I don't see any benefit to the B/W mode.
 
Sure it's not a day and night improvement on the color, I would have say about 10% improvement. I could have zoom in more but I think this is a good compromise between detail and overview of the area without the need for a 3rd wide angle camera. To me the BW image gives more detail for ID than color images.
