Before using this product
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.

also not malfunction.
