Input, Events & Output
About Input, Events & Output ...
Input
received from a wide variety of sources can be used to generate events in NetDVR.
Events
can in turn be used for automatically triggering actions in NetDVR, such as starting or stopping recording on
cameras, triggering e-mail or SMS notifications, making PTZ cameras move to specific preset positions, making video
automatically appear on NetMatrix recipients, etc. Events can also be used for activating output.
Output
units can be attached to output ports on many devices, allowing you to activate lights, sirens, etc. from
NetDVR. Such external output can be activated automatically by events, or manually from the NetGuard/NetGuard-
EVS.
Types of Events
You specify which types of input should generate which types of events. Basically, four types of events exist:
•
On many devices you are able to attach external input units to input ports on the device. Events based on
input from such external input units—typically sensors attached to doors, windows, etc.—are called
input
events
. Some devices also have their own capabilities for detecting motion, for detecting moving and/or
static objects, etc. (typically configured in the devices' own software), in which case you are also able to use
such detections from the device as input events.
•
Input may also be received in the form of TCP or UDP data packages, which can be analyzed and, if
matching specified criteria, used to generate events. Such events are called
generic events
.
•
Events may be based on NetDVR detecting motion on a camera. Such events are called
VMD (i.e. Video
Motion Detection) events
.
•
Finally, events may be generated manually by users selecting them in their access clients. Such manually
selectable events are traditionally called
event buttons
.
Specifying Input, Events and Output
In NetDVR, your main entry point for configuration of input, event and output handling is the
•
By clicking the
Administrator
window's
I/O Setup...
button, you open the
, in which you are able
to specify each individual
input event
,
VMD event
and
output
.
•
By clicking the
Administrator
window's
Event Buttons...
button, you open the
, in which
you are able to specify
event buttons
for manually triggering events-controlled activity.
•
By clicking the
Administrator
window's
Generic Events...
button, you open the
which you are able to specify
generic events
.
•
By clicking the
Administrator
window's
I/O Control...
button, you open the
, in which you are
able to
associate specific events with specific output
. This way you can, for example, specify that when motion
is detected on a camera (typically specified as a VMD event) a siren should automatically sound (output). If
you want users to be able to manually activate output when operating specific cameras, you specify this in
the
Output Settings for [Device Name] [Camera Name]
.
