I have 5 lightly-used like-new unlocked/reset/unbound 16-port PoE Uniview NVR302 16P NVR units for sale. 3 are S2 series (retail $869) for $90 ea., 2 are S1 (retail $569) for $60 ea.. The S2 series added a few additional VCA search features to the firmware, and continue to receive firmware updates - the S1's have no firmware updates planned after 2023, but still provide robust features (including VCA). Selling because I've upgraded to NVR304's.
Both models allow up to 16 cameras (up to 8MP 4K, Ultra265/H.265/H.264 - you can run 16 cameras simultaneiously at 720p/30fps) and support ONVIF and RTSP. All have 2 SATA drive ports (redundant or spanned), up to 10TB per drive. All are NDAA compliant (safe), have simultaneous VGA (1080p) and HDMI (4K) direct output, and IMHO, the best web gui in the industry - and features from basic to advanced.
Price includes 1 set of sata power/data cables, usb mouse and power cable - you can add an 8TB WD Purple 3.5" surveillance drive for $70 ea. (3 available), or a 3TB Seagate Skyhawk drive for $30 (1 available) if you want.
If you're not familiar w/these units, I'd suggest you download & check out the user manuals prior to buying.
