About the face matching function

This recorder (WJ-NV200K, WJ-NV200VK or WJ-NV200K/G) has the face matching function that compares the registered face
images with a face displayed on live images to detect a person with a closer match. When the person is detected, it is possible
to activate an alarm notification.
To use the face matching function, there are following restrictions.
• Only Camera 1 is available.
• A camera supporting the face detection function is required.
Refer to the "readme.txt" on the provided CD-ROM about the available cameras.
The maximum number of faces that can be detected simultaneously depends on the detection performance of the camera.
• When "Alarm action" is selected for "Mode" of "Advanced face matching alarm setup" (☞ page 58), the settings on the
"Advanced recording setup" page (☞ page 54) for Camera 1 will automatically be changed as follows.

played.
• While the face matching function is being activated, the maximum number of multi-screen segments is 4.
• The performance of the face matching function depends on the detection performance of the camera and recorder. When
many people appear on images at the same time, the following problems may happen: It may take time for face matching or
several face images may not be matched.
• Face matching alarm does not apply event recording.
