5. 

Screw the four HDD mounting screws provided into the holes on the underside of the HDD until the screw heads are about  
1/8 inch above the surface. 

6. 

Position the HDD in the recorder chassis with the HDD mounting screws fully seated in the holes and slots in the bottom of the chassis. 
The HDD should be above the front panel ribbon cable, and under the front panel black cable. See the photo above for the location of 
these cables. 

APPENDIX A 

HDD Installation

The following procedures illustrate hard disk drive (HDD) installation in a recorder without an HDD, and installation of a second HDD. If you 
purchased your NVR without a HDD, or you want to replace the HDD installed in your NVR or add another, use this procedure as a guideline. 

NVR compatible HDDs

For the best performance of your system, install only a high-reliability security grade HDD, such as Western Digital® Purple series or 
GreenPower™ series HDD. Security grade HDDs are designed to stream video efficiently and have a very low failure rate. 

The NVR can accommodate one HDD, with a capacity up to 6TB. 

HDD Installation 

Cables and screws needed to install the HDD are provided. 

CAUTION

Follow recommended electrostatic discharge (ESD) guidelines while performing this procedure. Install the HDD in a static-free 
environment, wearing a certified ESD wrist strap. If a static free environment and ESD wrist strap is not available, touch the bare metal of 
the NVR chassis frequently when installing the drive to dissipate the static charge naturally generated on your skin and clothing and avoid 
touching electronic components.

1. 

Power off the NVR, if necessary, then disconnect the power adapter and all other cables from the recorder. 

2. 

Remove the top cover from the NVR by removing the six cover screws. Two cover screws are located on each side, and two are located 
on the back. See the drawing below. Save the screws for use later. 

3. 

The photo below shows the inside of the recorder without an HDD. Become familiar with the items identified in the photo.
