Thinking about doing a comparison. ADI had them in stock.

Hello Steve,
Thank you. Currently I can't decide between these two cameras:
DS-2CD2T87G2-LSU/SL - older model = 1/1,2" cmos - only 2x LED light
DS-2CD2T87G2H-LISU/SL - newlest model = 1/1,8" cmos and 2x IR and 2x LED light
I have 2x LED halogen lights around the house on each wall 2x 50W LED. So I think it's better to go for an older version with a better, bigger sensor without IR illumination.
Or am I mistaken?
The newer one with IR and 1/1.8" sensor is $15 cheaper on eBay
I wanted a 2.8" optic, but since I have small distances around the house, I got the 4mm optic version.
An acquaintance told me to buy a camera with a 180-degree angle for each wall ( DS-2CD2387G2P-LSU/SL ). But they are only 2x 4mpx sensors and I think the image quality will be nothing much. , but again only 3 cameras would be enough. Instead of 6.
I have only physically tested the 4mp cameras and the 8mp cameras. Not this 180 degree. Should I try to borrow it somewhere?
I also tried simulation via: IP Video System Design Tool 2024
What would you recommend?
Thank you very much for your willingness.
If there is enough light - then you will not use any LEDs and work in full color.
White light in cams are gimmicks - they don't have enough power, they overexpose people faces and also generates questions from neighbors about camera and what are they recording...
The best quality / value cameras on market now are the 4Mpx one on 1/1.8" sensor..
They give the best day & night quality, are most universal and don't have any big problems...
8mpx at 1/1.8" are too small sensor size (too small pixels) to work good at night..
Here a nice thread where someone are comparing 4 vs 8 mpx on 1/1.8" sensor at night:

8mpx 1/1.2" cams can generate very nice picture at night.. but those big sensors create problem with shadow depth of field aka Bokeh effect (Bokeh – Wikipedia, wolna encyklopedia). Both HIK/Dahua are trying to use digital sharpening a lot to hide that problem - but this create a lot of problems with digital noise & video compression, which can't handle that amount of digitally enhanced details...
3-4 years ago when first 8mpx 1/1.2" cams shown on market they very big hit, but now everyone knows long list of problem with them and they are not so popular..
Long thread about 8mpx 1/1.2" in Dahua version - but all problems are the same also in HIK version.

8MP IPC-T581R-ZE-S3 fuzzy view
Hi, I decided to renew my 10 year old cameras and ordered some from Andy, I have the 4MP IPC-T541R-ZE-S3 and then ordered the 8MP IPC-T581R-ZE-S3 as I thought the 8MP would give me a better clearer view. I have spent a few weeks trying different settings and resetting the 8MP camera various...

Worlds First Review - Dahua DH-IPC-HDW5849H-ASE-LED / IPC-Color4K-T - 2.8mm Turret
Ok, who's ready for not only a review BUT another World's First Review ? You heard it here first, new camera in hands and almost ready to review. Thanks as always goes to Andy (@EMPIRETECANDY) for providing this camera in exchange for a fair, honest, non biased, no holds barred review. I’ve...
Buy a camera for the shot YOU are trying to capture. This is step 1. What are you trying to record exactly? Ask yourself this. Go to each camera spot as use your own eyes. They will tell you you we need a panoramic or not. If you want general front and backyard shots then a regular non PTZ will do it. Simple watching a goldfish pond, no need for a panoramic.
If you are trying to read license plates or faces, things that need a ton of detail, then a PTZ should be looked at. $$$$
