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

example, 10 seconds, select
