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 Black Miller

firmware bug, most likely. This could be fixed with a firmware fix but I can't wait: this rather expensive item will be returned for a refund within my 30 day Revain window. The alarm inputs are important and have been verified by me in my tests. I received emails with photos and buzzer sounds. But the VIDEO was not recorded to disk as required by my very careful setup. I'm a hardware testing expert and I know when to keep them and I know when to throw them away and get my money back. THAT RETURNS.
