Reolink 12MP 8 dome cameras + NVR (16 channel) PoE kit $650

Costco has this 8-camera kit on sale until May, 31st.
NVR has 16 channels so you can extend with 8 more cameras. Includes 4GB storage (which is not great, but ok.)
I think you can also use cameras individually eg put an SD card and still have motion detection and sound without NVR – but you’ll need PoE adapter to power it.
