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 Kyle Hong

Better overall bandwidth than the previous version results in smoother videos when you have many 4K 30fps cameras. Much smaller and much quieter than the previous version - a big improvement. Noise reduction, storage capacity is slightly reduced - it can accommodate two large-capacity hard drives, not four small ones. The font on the screen is too small when the display is set to 4K video. This cannot be adjusted (firmware update?). This issue is worth the partial star deduction, but downgrading a product to 4 stars is too much of a penalty, so 5 stars.
