Review on 📹 Dahua NVR 16Channel POE NVR5216-16P-4KS2E: High Performance 4K Recording & Playback Pro Network Video Recorder by Paul Freeman

When we plugged it in, the fan is so loud it could stand in the room it was planned to be in. In the cupboard above the fridge with a monitor. It's just too loud to be in a "live space". I called the Dahua factory and was told that this is not a covered product and the factory does not recognize the serial number and is likely to be "counterfeit". manufacturer guarantee. We are very worried and not happy at all at the moment! Dahua says the seller is NOT an authorized dealer and a black market item! Don't know what to do now? Expensive product has no factory support or warranty! Stay away from this seller.
