Face matching function

Face recognition refers to a function that uses a connected camera supporting this function to detect facial fea-

tures of people and matches them against similar facial features recorded earlier or contained in live images.

The matching accuracy varies depending on installation, settings and adjustment of the camera, ambient envi-

ronment and object. Matching of facial features may therefore not work under the following conditions:

 • Whenilluminationisnotuniform,forexample,outdoors

 • Whenthefaceispartiallyconcealed(mask,sunglasses,helmet,etc.)

 • Whenthefaceisnotfacingthecamera

 • Whenasubjectismovingveryfast

 • 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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 time and date may sometimes skips. This is not malfunction.

The displayed time and date on the monitor and the recorder may sometimes not be exactly the same. This is

also not malfunction.
