CCTV DVR Alarm Input / Alarm Relay Output Setup

CCTV DVR Alarm Input / Alarm Relay Output Setup


This video will demonstrate how to connect
a magnetic door sensor to the alarm input of a CCTV DVR, we’ll also wire an alarm strobe
light to the relay output of the DVR and we’ll configure the DVR software to activate the
alarm light when a door is opened. We’re using an IDVR-PRO Surveillance DVR for this demonstration.
Here’s the alarm test panel that we use at CCTV Camera Pros. The magnet door sensor is
already wired to the alarm input port number one on the DVR and the strobe light and its
power supply are connected in line with the DVR’s relay output port number one. This is
how those devices are connected to the alarm ports on the back of the DVR.
The two wires from the door sensor simply connect to the alarm in port and a common
ground port. The strobe light is not quite as simple. This device has its own power supply,
in this case a 12 volt DC power transformer, so a relay alarm output port is used to connect
in line with the light and the power supply. The relay will be set to the normally open
position so that power cannot flow through the circuit. When an alarm event is triggered,
the DVR will close the circuit and allow power to pass through which causes the strobe light
to turn on. Next, we’re going to configure the software
on the DVR. First thing I’m going to do is select the menu button and select system setup.
From the system menu I’m going to select event and then alarm sensor. On the alarm sensor
screen you can see all the alarm inputs here and you can create name for each one, you
can set the operation to normally open or normally closed, in this case it’s going to
be normally closed because it’s a door sensor. I can link it to one or more cameras and I
can also link it to one or more alarm outputs. I’m also going to set it to sound a buzzer,
enable video popup and enable the on-screen display to popup.
Next, I go to the alarm out section. In the alarm out screen, again, I can give a name
to each of the alarm outputs, in this case I’m going to name it Lab Strobe. I’m going
to set the operation to this one normally open so the circuit is open and the light
is not on by default. You can set a duration for how long the relay output is engaged and
then you can click this test button to perform a test to engage the relay and make sure that
your strobe light is working correctly.

The last thing I want to do is I want to
set the DVR to record when the alarm is engaged. I’m going to click menu and go to record setup
and on the record screen I’m going to set it to intensive alarm recording which basically
means that the DVR is going to record continuously but then when an alarm goes off it’ll bookmark
that event. You can change the frame rate and the resolution of the DVR records at when
the alarm is engaged. That’s optional. Now it’s time to test the alarm input and
the alarm output and the DVR settings. I’m going to start this other camera to watch
the alarm panel and then when I open up the door a few things are going to happen. One,
it’ll go to camera two because that’s what the alarms associated with, it pops up the
on-screen display warning and it’s recording in alarm mode now and the strobe light was
going off. The recording in alarm mode, you can tell by that little a in the upper right
hand side and it’ll switch back to c for continuous recording after the alarm event is done. There
you go it switches back to c, now it’s recording continuously again. That was a very successful
test. To learn more about how to set up alarm inputs

    Watch this video to see magnetic door sensors trigger surveillance video recording and activate an alarm strobe light.

    This iDVR-PRO is configured to take the following actions when the door sensors are triggered. 

      ~ The DVR starts video recording.
      ~ The DVR sounds an audio buzzer.
      ~ Video from the CCTV camera associated with the alarm is displayed full screen.
      ~ An alarm message is displayed on the screen.

    The DVR can also be configured to send email alerts and FTP upload a pictures of events (not done in this video).

    The types of alarm sensors used in this video are just a few examples of the types that can integrate with a security DVR. Other types include: PIR motion detectors, glass break detectors, and infrared trip wires.

    For more information about how these sensors were wired and how the DVR software was configured, please visit this page.
