External Sensors and
Recording Duration
Each camera can have an external sensor
associated with it, allowing recording to occur
whenever the sensor is tripped (24/7, or only
during specific times).
External inputs must also be enabled for ‘pre-
alarm recording (>>), and can trigger:
• An email or alarm-alert;
• A camera to display automatically (and
optionally point to a specific 'preset'
location);
• Special (alarm overlay) subtitles to display;
• The ‘TV-Out’ feature (Spot Monitoring).
(See "Related Topics"--to follow/below.)
Locator: (Logged in at the Video Server as
a "Supervisor"),
Select: [Utility], then [Recorder Setting].
Select Alarm , and then make your desired
selections for each camera:
--------------------------------------------------
(External Alarm Input)
Enable: Select this to enable recording when
the camera's associated sensor/input is
triggered.
TechTip: This must also be selected if you are setting
up 'pre-alarm recording' associated with video motion
detection.
(in sec): How long each camera will record
when its external sensor is tripped.
NOpen: Select this if the sensor is normally
open, and closed when tripped (vs. the other
way around).
(Pre-Alarm Recording)
This feature is covered separately, since it affects
external sensor-activated recording, as well as video-
motion triggered recording (browse / next topic).

When finished, click [OK], and then

Recording Mode for External
Alarms
You can configure the relative duration for
externally-triggered alarm recordings (i.e.,
whether the duration set previous/above is
used as-is, or is taken as a minimum or
maximum recording time versus the triggering
event itself).
Locator: At the Video Server PC (will
prompt for "Supervisor" login),
Select: (Windows task bar) Start, Settings,
Control Panel, DSR Configuration.
Desktop Link: There should also be a link to this on
your desktop called "NetVision Configuration".
Tips: If you cannot access the Windows task bar,
press Ctrl-Esc (or your 'Windows' key). To view the
names for items on the task bar, click a blank area on
the bar, and then 'hover' your mouse pointer over each
item.
Logon as a "Supervisor" when prompted.
Then, double-click Set Alarm Mode in the list.
When the screen appears, make your desired
selection(s).
--------------------------------------------------
Pulse Mode: The recording duration will
match that as set under “(in sec.)”,
previous/above.
Level Mode with Minimum Recording Time:
The recording duration will be as set under “(in
sec.)” or for as long as the triggering event
remains in effect—whichever is longest (i.e.,
the set value is taken as a minimum).
Level Mode with Maximum Recording Time:
The recording duration will be as set under “(in
sec.)” or for as long as the triggering event
remains in effect—whichever is shortest (i.e.,
the set value is taken as a maximum).
