From a security standpoint, I would not recommend Wi-Fi or battery powered devices if you can help it. There’s been cases across the US where burglars have used Wi-Fi jammers prior to burglaries to take cameras offline. I have a Wi-Fi doorbell camera but its backed up by a hard wired PoE camera that can see the approach to my front door.
In terms of brands, there’s lots of good stuff out there these days. Ubiquiti (as posted above) makes good stuff but I don’t think its very cost effective. If price is not an issue then I would highly recommend looking at AXIS, Verint, and Hanwha/Wisenet. Those brands are what you see getting used on the commercial side for facilities with high levels of security (banks, colleges, prisons, etc). Hanwha/Wisenet (Samsung) has a line of camera called the A-series that performs pretty well for a more budget conscious individual.
Personally, I have my house wired up with PoE Reolink cameras. I think the performance is good for the price. I think my biggest complaint with Reolink is the ghosting during nighttime. It’s a well known issue with the cameras and I think it has to do with the sensors they use. What drew to that brand though was the ease of connecting to cameras outside of my network. My parents, siblings, and myself all use Reolink and we can share our cameras with each other. So I can see my parents driveway and they can see mine as well. Probably not very secure from an IT perspective but it is helpful with looking after elderly parents when you live in a different region.
I tend to recommend that people avoid Hikvision and Dahua, mainly if you intend to connect them to your network. They’ve been caught before sending signals to Chinese servers and both companies have ties to the CCP so they are definitely not very privacy conscious. Many countries have actually banned them from being used on government facilities for this reason. If you isolate them from network access they actually perform pretty well from a cost vs capability standpoint.
