  • Up to 16 clients can monitor images and control WJ-ND400 simultaneously

The WJ-ND400 ia a high performance network hard disk recorder designed specifically to meet the demands of megapixel camera recording where high data throughput and large storage capacity are required.

Large storage capacity

64 network cameras can be connected to the WJ-ND400 and their images and audio recorded simultaneously. The NVR has 9 serial ATA HDD slots with each optional extension unit also containing 9 serial ATA HDD slots for additional capacity, making the WJ-ND400 ideal for large scale surveillance systems. With hot plug support, drives can be replaced without any downtime, allowing 24/7 operation.


For high reliability, the WJ-ND400 supports RAID 5/6; enabling image data to be stored across multiple HDDs (minimum 4 HDDs required). If one HDD (or two drives for RAID 6) should fail, recordings can be recovered from the remaining HDDs without any loss of data. The unit also features embedded OS and data encryption.


The WJ-ND400 is both MPEG-4 and JPEG compatible and enables versatile recording functions including manual, scheduled, emergency, event and external timer recording, providing unrivalled flexible recording options. With a range of alarm actions including alarm recording, e-mail notification, alarm message, terminal output, FTP transfer and camera positioning the recorder ensures that a moment is not missed by users of the system.

To search recordings the intelligent VMD function allows movement in a specified area in the recorded images to be quickly searched. In addition, the filtered search function can search a record by Time & Date, Event Type and Camera number.

Two network interfaces are provided on the recorder allowing the client network to be separated from the camera network. This ensures that the camera network performance is not impacted by users monitoring the system. This can also act as an additional security measure allowing cameras to be placed within a separate network with access only through the NDR.

Low set-up costs

When i-Pro network cameras are connected to the WJ-ND400, their IP addresses can easily be obtained through the Easy IP Set-up feature. By reducing the time and labour required for network set-up, Easy IP Set-up lowers installation costs and maintenance costs.
