Tracker:
In the Tracker field you see an arrow, which indicates the current motion in the
video image. By means of check boxes in the four corners, the desired direction can
be activated. If, for example, all movements to the “left” and “upwards” are to
activate an alarm, then mark the top left corner. If all movement to the “left”is to
activate the alarm, then check the left upper and the lower left corners. Note the
movements indicated by the arrow in the video image over a long period and at all
light levels likely to be encountered in practice. Click the check box in order to
activate the corresponding directional component.
Relay Setting
ó Relay Configuration
The switching conditions for the relay output can be configured. The function of an open
switching relay (normally closed contact) or a closed switching relay (normally open
contact) can be specified. It is also possible to specify whether the output should operate
as a bistable or as a monostable. In bistable operation, the activated state of the relay
remains as switched. In monostable operation, the time can be selected after which the
relay is to revert to its steady state. Various events can be selected to automatically
activate the output. In this way, for example, it is possible to switch on a floodlight when a
motion alarm has been detected and to switch the light off again at the end of the alarm.
Please note that changing the default configuration the relay will work as set when the
camera is powered on but as indicated in the previous session when powered off.
Idle state:
Select Open if the relay is to operate as a normally open contact or Closed if it is to
operate as a normally closed contact.
Operating mode:
Select the operating mode for the relay. If, for example, a lamp is switched on by an
alarm and is to remain on when the alarm has ended, select Bistable. If an acoustic
signal activated by an alarm is to remain on for a period of, for example, 10 seconds,
select 10 s.
Relay follows:
Select a particular event by which the relay is to be activated as required.
