I am using HikVision I bought from Alibaba about 5 years ago. They have been rock solid. No firmware updates though as they are grey market cameras. There are so many options now though. Lots of cheap off brands available now. Just black hole them on your firewall so they cannot call home and life is good.

So I need to replace. I did purchase the Amazon wifi cams. But I feel alot more comfortable using the existing cat6+Poe runs.
