I've got a mostly Reolink system (mix of turret, bullet & PTZ cameras) with a Uniview NVR501-08B-P8 (8Tb drive).
Power/network is managed by a Yuanley 11 port gigabit switch (8x POE, max 120W), currently £49 on Amazon - incredible value and has been rock solid in the two years I've owned it.
I put micro SD cards in each camera (128Gb in each, except the PTZ which has a 512Gb), so I can quickly view & snip compressed footage on my phone via the Reolink app, then if I need to access the full resolution recordings or search specifics using AI, I can use the NVR; it displays on the TV in my study, or I can access it via my PC/Tablet.
Really happy with the system - the cameras are great quality and Reolink's warranty is first class (they've replaced two cameras that developed condensation with the next models up, no quibble).
The Uniview NVR was a bit of a steep learning curve to set up (Onvif/Static IP issues), but I paid £150 with a 4Tb drive on an eBay deal (about 70% under RRP) and although it's not quite as user friendly as the Reolink option, it has a lot more features and headroom for more (higher res) cameras in the future.
