zmtrigger.pl - ZoneMinder External Trigger Script
|
|
|
|
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
|
|
|
|
This script is used to trigger and cancel alarms from external connections
|
|
|
|
using an arbitrary text based format.
|
|
|
|
|
|
|
|
This script offers generic solution to external triggering of alarms. It
|
|
|
|
can handle external connections via either internet socket, unix socket or
|
|
|
|
file/device interfaces. You can either use it 'as is' if you can interface
|
|
|
|
with the existing format, or override connections and channels to customise
|
|
|
|
it to your needs.
|
|
|

|
|
=item B<id>
|
|
|
|
|
|
|
|
is the id number or name of the ZM monitor.
|
|
|
|
|
|
|
|
=item B<action>
|
|
|
|
|
|
|
|
Valid actions are 'on', 'off', 'cancel' or 'show' where
|
|
|
|
'on' forces an alarm condition on;
|
|
|
|
'off' forces an alarm condition off;
|
|
|
|
'cancel' negates the previous 'on' or 'off';
|
|
|
|
'show' updates the auxiliary text represented by the %Q
|
|
|
|
placeholder, which can optionally be added to the affected monitor's
|
|
|
|
timestamp label format.
|
|
|
|
|
|
|
|
Ordinarily you would use 'on' and 'cancel', 'off' would tend to be
|
|
|
|
used to suppress motion based events. Additionally 'on' and 'off' can
|
|
|
|
take an additional time offset, e.g. on+20 which automatically
|
|
|
|
cancel's the previous action after that number of seconds.
|
|
|
|
|
|
|
|
=item B<score>
|
|
|
|
|
|
|
|
is the score given to the alarm, usually to indicate it's
|
|
|
|
importance. For 'on' triggers it should be non-zero, otherwise it should
|
|
|
|
be zero.
|
|
|
|
|
|
|
|
=item B<cause>
|
|
|
|
|
|
|
|
is a 32 char max string indicating the reason for, or source of
|
|
|
|
the alarm e.g. 'Relay 1 open'. This is saved in the 'Cause' field of the
|
|
|
|
event. Ignored for 'off' or 'cancel' messages.
|
|
|
|
|
|
|
|
=item B<text>
|
|
|
|
|
|
|
|
is a 256 char max additional info field, which is saved in the
|
|
|
|
'Description' field of an event. Ignored for 'off' or 'cancel' messages.
|
|
|
|
|
|
|
|
=item B<showtext>
|
|
|
|
|
|
|
|
is up to 32 characters of text that can be displayed in the
|
|
|
|
timestamp that is added to images. The 'show' action is designed to
|
|
|
|
update this text without affecting alarms but the text is updated, if
|
|
|
|
present, for any of the actions. This is designed to allow external input
|
|
|
|
to appear on the images captured, for instance temperature or personnel
|
|
|
|
identity etc.

|
Note that multiple messages can be sent at once and should be LF or CRLF
|
|
|
|
delimited. This script is not necessarily intended to be a solution in
|
|
|
|
itself, but is intended to be used as 'glue' to help ZoneMinder interface
|
|
|
|
with other systems. It will almost certainly require some customisation
|
|
|
|
before you can make any use of it. If all you want to do is generate alarms
|
|
|
|
from external sources then using the ZoneMinder::SharedMem perl module is
|
|
|
|
likely to be easier.
