You didn't showed any footage how moving people/cars are looking at night..
How many details are visible (faces, car plates etc)..
This is final exam for any camera - is good or not.
About 2K price question - no it's not worth 2K to the average person.
Especially that at this price, You have 5216-EI NVR + 6 * 5442-ZE (or Color4K-T) + 2 * 5442-Z4E (or 5241-Z12E) combo in Andy shop, with which You can do complete house CCTV system with 6 overview cams around house and 2 zoomed at street ones..
Yes, it will have a little worse night performance. But it will cover all house and street needs for 95% folks..
But it can be worth for You.. As You told, you want to see better images of people across the street at night...
