3.2 Check Unpacked NVR

When you receive the NVR from the forwarding agent, please check whether there is any
visible damage. The protective materials used for the package of the NVR can protect most
accidental clashes during transportation. Then you can open the box to check the accessories.
Please check the items in accordance with the list. Finally you can remove the protective film
of the NVR.

3.3 About Front Panel and Rear Panel

The model number in the stick on the bottom of NVR is very important; please check
according to your purchase order.
The label in the rear panel is very important too. Usually we need you to represent the serial
number when we provide the service after sales.

recommend to use HDD of enterprise level or surveillance level. It is not recommended to use
