Motion alarm off
VIP
is equipped with a video motion
detection feature. The video scene is
constantly monitored for relevant
motion.
The sensitivity needs to be adapted to
the respective environment and the
acceptable false alarm rate: for a lower
false alarm rate select a lower sensitivity
and vice versa. Some experimentation is
required to find the best setting. The use
of the motion detection feature is only
recommended indoors and under con-
trolled lighting conditions.
For advance settings, for example
masking regions of interest inside the
video frame, interworking with a software
decoder such as
VIP -SW1
is required.
Alarm input pin off If external sensors or simple contacts or
switches are to be used in combination
with
VIP
, the alarm input needs to be
selected. In addition the polarity of the
signal may be changed from active high
to active low. For example, depending
on the configuration, an alarm may be
triggered when a contact opens or
closes.
Alarm status off Current alarm activation status can be
displayed via on-screen display, similar to
the name, date and time stamping, dis-
cussed above.
If configured to be on, the status of the
activated alarms, namely video, motion
and input, is depicted in the upper left
hand corner of the video frame. Alterna-
tively, the display may be activated as
soon as an alarm condition is reached.
This way, the video frame corresponding
to the alarm condition is clearly marked.
Furthermore there is a choice to keep
the status display, once an alarm has
been triggered, even when the original
cause of the alarm is no longer present,
or to have the status display follow the
alarm condition.
Alarm message string empty In connection with the alarm status
explained above, a user defined text
string may be displayed on screen in the
upper right hand corner. The text string is
typically used to convey additional
alarm related information to the remote
viewer, i.e. the guardsman for example.
