Before using this product
About the face matching function (option)
By registering the license of the additional business intelligent kit, the face matching function, that detects faces
whose features are closed to the registered faces by comparing face images in live image with the registered
face images, will become available. The matching accuracy varies depending on installation, settings and
adjustment of the camera, ambient environment and object. Matching of facial features may therefore not work
under the following conditions:
When illumination is not uniform, for 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 influence of strong external light (such as the headlights of a car, rising sunlight or setting sun-
•
light)
* Configure the settings of the camera supporting this function before attempting to use the face matching
function.
Motion detection (VMD) function
The motion detection (VMD) function of cameras detects motions referring to changes of luminance (brightness)
in areas set in advance.
The motion detection function will not effectively work in the following situations or may sometimes be malfunc-
tioning.
When there is a very little difference in luminance (brightness) between a background and a subject
•
When brightness of images is low such as at night
•
When a subject moves very slow
•
When a subject is very small
•
When the amount of rays of light incidence changes frequently such as at a window or outdoors.
•
When light such as sunlight or car headlight comes from outside
•
When a fluorescent lamp flickers
•
When a subject has depth
•
When configuring the motion detection settings, check the function performance both in daytime and at night
after appropriately configuring the area settings and the sensitivity settings according to the camera installation
conditions and possible movement of subjects. When the detection function does not work or false detection
occurs, use a sensor separately. Refer to the operating instructions of the camera for further information.
Time display of recorded images
When displaying recorded images, the displayed date & time may sometimes skips. This is not malfunction.
The displayed date & time on the monitor and the recorder may sometimes not be exactly the same. This is
also not malfunction.
Response to the mouse operations
While this recorder is processing multiple operations at the same time, the response to the operations from the
connected mouse may temporarily become slow. This is not malfunction.
