Motion detector
The VIP contains an integrated video sensor that can register changes in the
video signal based on image processing. These changes are triggered primarily
by any movement that is detected in the camera's field of view.
The sensitivity of the video sensor can be adjusted, so that an alarm is generated
only if a given threshold is exceeded.
In order for the sensor to function, the following conditions must be satisfied:
]
The motion detector must be enabled.
]
At least one cell must be activated.
]
Individual parameters must be configured correctly to suit the operating
environment and the responses desired.
]
The sensitivity must be set to a value greater than zero.
Warning!
Reflections of light (off glass surfaces, etc.), switching lights on or off or
changes in the light level caused by clouds passing across the sun can
spuriously trigger the video sensor and generate false alarms. Perform
sufficient tests during the day and night in order to ensure correct operation
of the video sensor. When the system is used for surveillance of indoor
areas, ensure constant lighting during the day and at night. Uniform
