Grandstream Surveillance Buyer's Guide - Manual (Page 26)

Integration Directly with IP Cameras
All Grandstream cameras support audio output (the ability to call a
camera and have the audio played through an external speaker con-
nected to the camera). Additionally, many of Grandstream’s indoor
cameras feature not only audio output but also audio input (to
speakers) and alarm inputs and outputs. The ports for these func-
tions are found directly on the cameras themselves and let you:
• Connect existing security sirens to the alarm outputs of the
cameras so that when a camera triggers an alarm, it notifies
the siren and the siren goes off.
• Connect existing motion or door sensors to the alarm inputs
of the camera so that if the motion/door sensor goes off,
the camera is notified and triggers its own alarms and alarm
notifications.
• Connect existing intercoms microphones to the audio input
of a camera to allow the audio to be played through the
cameras speaker or to a speaker connected to the camera.
• Connect speakers to the audio output of the camera so
you can to call the camera’s extension and talk through the
speaker, for example.
Once these devices are connected to the cameras, users will need to
login to that cameras web user interface in order to tell the camera
what to do when it senses an alarm, and what to do when it’s told
an alarm triggered by a 3rd party device. The Alarm Action section of
the Web UI is where these features are setup. Make sure a camera’s
alarm schedule is set to record all day for 24/7 alarm possibilities.
