Alarm inputs
The alarm inputs on the recorder are used for event
control via externally wired detectors (door contacts,
motion detector, smoke detector, light barriers, etc.).
On the recorder side, the inputs can be used to activate a
recording, alert via CMS or send an alarm email, among
other things. The alarm inputs are purely switch contacts
(Normally Open/Normally Closed) which must not be
voltage controlled.
Note
Following the connection of the detector to the
alarm input of the recorder, the behaviour in the
normal state (NO/NC) and the event reaction must
be programmed in the settings menu.
Alarm outputs
The alarm outputs on the recorder are used for the action
control of externally wired devices/actuators (sirens,
lamps, door openers, etc.). The alarm output switching
takes place via integrated relays on the recorder. In order
to prevent damaging the relay/recorder, the device’s
maximum switching power must not exceed the specified
values of 12 V / 1 A.
Note
After the actuator has been connected to the
alarm input of the recorder, the event reaction
must be programmed in the settings menu.
RS-485 output
The RS-485 output on the recorder is used to control
analogue PTZ cameras.
Analogue HD cameras with an integrated PTZ function
are fully controlled via the BNC cable.
The use of the interface is intended as an alternative to
the use of cameras with external motor control.
Connection
Description
Depending on the recorder
model
, 1
–16 inputs are available.
First, plug the detector contact in
an open input (IN1-16) and then
connect the grounding contact (G).
Connect more detectors in the
same way:
IN1
G
IN2
G
IN3
G
….
IN16
G
It does not matter whether you
connect all detectors to one
grounding contact or divide them
up among the available contacts.
Use terminal blocks in order to
connect multiple detectors to one
grounding contact.
Connection
Description
Connect the PTZ control by using
the Transmit and Receive pins.
Connection
Description
Depending on the recorder
model,
1
–4 outputs are available.
First, plug the actuator/device in
an open output (OUT1
–4) and
then connect the grounding
contact (G).
Connect further actuators in the
same way:
OUT1
G
OUT2
G
OUT3

It does not matter whether you
connect all actuators to one
grounding contact or divide them
up among the available contacts.
