Review on Amcrest 4K NV5232 Network Video Recorder - Supports up to 32 x 4K IP Cameras, 1080P/3MP/4MP/5MP/6MP/12MP Compatibility, works with 2 x 10TB Hard Drives (Not Included), No PoE Ports by Stuart Dunn

Requires a browser plugin to view videos when accessed from the website. The layout is complex, I'm still studying all the possibilities of the box. I'm not sure how it will support 32 4k cameras as it only has one gigabit port, they should have two ports and you should be able to chain them in one lacp command, or a 10gb or sfp port would be nice. Video playback navigation sliders could be easier to use, you have to fiddle with them to view the footage. Other than that, it's a big upgrade over my Swann unit.
