Preface
The network disk recorders WJ-NX310K Series equipped H.265 CODEC and are designed for use within a H.265 surveillance
system, and record images/audio from up to 16 network cameras (hereinafter, cameras) on the hard disk drives (HDDs).
Number of cameras to be used in the system can be increased to 32 (maximum) by purchasing the Additional Camera Kit
(WJ-NXE32W, WJ-NXE33W).
Hereinafter, WJ-NX310K referred to NX310, or the recorder.
This recorder supports connection with a monitor equipped with the HDMI (High-Definition Multimedia Interface) connector.
Connection using an HDMI cable (optional) offers display of playback/live images with superior quality.
It is possible to display images from multiple cameras, switch those images and perform basic operation of the camera.
Introduction
Features
High-definition image monitoring is available
Images from up to 32 cameras with the image capture size of 4K can be saved as video data.
This recorder also supports the HDMI output to 2 monitors that can display recorded images and live images from the cameras
in high definition.
Quick setup and operations
By connecting a mouse (accessory) to this recorder, quick operations are available while viewing a monitor.
By using "Easy Start", the cameras are automatically recognized and settings can be configured without operations from a PC*1.
Recorded images can easily be searched using calendar or time line.
* A PC will be necessary for some of the camera settings and viewing the instruction manual.
RAID function
This recorder enables operation of RAID 1.
HDD stand-by control function
By temporarily pausing HDDs other than those which are recording or waiting for recording, set a mode not to count the
operation time of a hard disk drive and extend the time it takes to replace the HDD.
*This function requires 3 or more HDDs for single mode. This function does not apply for mirroring mode.
The copy port equipped
You can copy the images recorded on the camera with an external HDD and USB memory (sold separately).
The copied images can be played, printed or saved using the dedicated viewer software.
Secure communication function
The SSL communication can be used for communication between the recorder and camera, and between the recorder and PC.
Also, by registering a license of a secure communication kit (option), you can use the function to encrypt the video data itself.
MP4 download function
Recorded camera images can be copied to USB media or downloaded to a PC in MP4 format.
Third-party cameras can be connected
In addition to our cameras, third-party ONVIF®compatible cameras can be connected. Third-party cameras can also be
connected via RTSP by specifying the URL.

Protection against power failure
The built-in function protects the equipment and recorded data in the event of AC power interruption such as sudden power
failure. This function makes it possible to turn off the AC power without having to stop recording or perform other operations.
*It does not guarantee that the equipment will not malfunction in the event of all possible power interruptions.
In addition, there is a possibility that the data recorded immediately prior to the power failure will not be saved.
If it is necessary to guarantee the operation of the equipment or to continue recording operation even in the event of a power
failure, use an uninterruptible power supply or similar device in combination.
