Preface
Additional Business Intelligence Kit WJ-NXF02, WJ-NXF02W (hereinafter, this product) is a license kit intended
to improve the usefulness of Network Disk Recorder (hereinafter, recorder) WJ-NX200K and WJ-NX200K/G. By
registering the license of this product, the face matching function will become available and it checks if facial
features of people in live images are matched with facial features of the registered people, and issues an alarm
if a matched face is found. The statistical processing for the results of the face matching will also become available and it displays the result on the main monitor connected with the recorder.
Features
Face matching function
By matching registered face images with a face displayed on live images in real time and by notifying the
matching result, it will be possible to check guests or discover suspicious people. That can be an aid to crime
prevention.
Statistical processing function
The number of people whose faces are detected can be classied according to each gender and age for a day
or a specied time period to create and display a statistical graph. The age distribution is classied by color. In
addition, the statistical result can be saved as a CSV le* in a USB medium or on a PC connected via a network.
* CSV le: A le that can be edited using a spreadsheet software such as Microsoft® Ofce Excel®.

• To use this product, Camera 1 or Camera 2 is required to support the face detection function.
Refer to the "readme.txt" on the CD-ROM provided with recorder about the supported cameras. The maximum
number of faces that can be detected simultaneously depends on the detection performance of the camera.
• The statistical processing function and face matching function are available only with Camera 1 and Camera 2.
•When using this product, the settings for Camera 1 are automatically changed for face matching.
Compression: H.265/H.264
Image capture size: SXVGA (1280×960)
Frame rate: 5 ips

When shooting images on a place where strong light sources may affect from outside, the following settings
can reduce the light inuence.

Cases not suited for face matching
The matching accuracy varies depending on installation, settings and adjustment of the camera, ambient environment and object. Therefore, face matching may not be performed in the following cases.
•Illuminance levels are dispersed. (Example: Outdoors)
•Faces are interrupted by such objects as medical masks, sunglasses or helmets.
•Faces are not directed to the front side.
•Photographic subjects are moving quickly.
• Under the inuence of strong external light (such as the headlights of a car, rising sunlight or setting sunlight)
To improve the performance of face matching
• Register the target face images from the images recorded by the camera installed under the same conditions.
•Perform settings for the camera so that the camera can shoot face images at a balanced illuminance level
both in the daytime and nighttime.
•Install the camera so that the camera can move within the assumed moving pathway of photogenic
subjects.
•Congure the settings of the people counting area and the face matching / age and gender judgment area
(☞ Page 15) to avoid counting the same person repeatedly and avoid targeting people's faces printed on
a poster.
•Congure the setting so that the people counting area is included in the face matching / age and gender
judgment area.
