2.2 Limitations
Please note the following considerations:
IVMD is suitable for monitoring boundaries, fences and enclo-
sures and for the protection of pipelines, overland lines etc.
However, in certain environments the use of this type of motion
detection system may not always be advisable; this is because
movements may not always be detected or too many move-
ments may be detected owing to reflections.
Movements may be falsely detected if there is:
– a reflective metal background
– glass (glazed building frontages)
– water as a background
Large areas of reflected light can also cause spurious motion
detection. However, light reflections caused by falling rain-
drops, for example, are small enough to be ignored for statisti-
cal purposes and owing to the uniform nature of their motion.
Objects that always move uniformly (such as clouds) do not
impair the detection of other objects and do not trigger false
alarms.
A constant background is necessary in order to detect motion
reliably and to assign that motion to a certain object. The more
the background moves, the harder it is to distinguish moving
objects from it. For instance, a person walking in front of a
hedge that is moving in the wind will very probably not be
detected.
