Example 1. Visualization of operating the Queue length detection in the Video surveillance monitor
For the script to work correctly, you must first create and configure the Queue length detection object (part of the Detector Pack package), Camera and Captioner objects (below, instead of the N, M, L characters, set the corresponding numbers of the Queue length detection, Camera and Captioner objects) in Axxon PSIM.
//Event reading by the queue length
if (Event.SourceType == "OCCUPANCY_COUNTER" && Event.SourceId == "N" && Event.Action == "OCCUPANCY") //N - Number of Queue length detection
{
var n=Event.GetParam("occupancy");
//Displaying the queue length by the Captioner in the Monitor
DoReactStr("CAM","M","CLEAR_SUBTITLES","title_id<L>"); //M - Number of Camera L - Number of Captioner
DoReactStr("CAM","M","ADD_SUBTITLES","command<Queue length: "+n+" person(s).\r>,page<BEGIN>,title_id<L>"); //M, L - the same
}
As a result, when the corresponding camera is displayed in the Monitor, a text message about the current queue length will be superimposed on the video image.
You can configure the font, color and position of text on the settings panel of the Captioner object.
Note
When you use the page<BEGIN> and page<END> parameters, the corresponding fields of the captions database are filled in. This enables data search using the Captions search interface object.
Example 2. Visualization of operating the People counter detection in the Video surveillance monitor
For the script to work correctly, you must first create and configure the People counter detection object (part of the Detector Pack package), Camera, Captioner and Macro objects (below, instead of the N, M, L, P characters, set the corresponding numbers of the People counter detection, Camera, Captioner and Macro objects) in Axxon PSIM.
//Event reading and counting of entered people
if (Event.SourceType == "PEOPLE_COUNTER" && Event.SourceId == "N" && Event.Action == "IN") //N - Number of People counter detection
{
i = Itv_var("counter_i");
k = Itv_var("counter_k");
i++;
Itv_var("counter_i")=i;
//Displaying the number of people by the Captioner in the Monitor
DoReactStr("CAM","M","CLEAR_SUBTITLES","title_id<L>"); //M - Number of Camera L - Number of Captioner
DoReactStr("CAM","M","ADD_SUBTITLES","command<Number of people (entering/exiting): "+i+" / "+k+"\r>,page<BEGIN>,title_id<L>"); //M, L - the same
}
//Event reading and counting of exitng people
if (Event.SourceType == "PEOPLE_COUNTER" && Event.SourceId == "N" && Event.Action == "OUT") //N - Number of People Counter detection
{
i = Itv_var("counter_i");
k = Itv_var("counter_k");
k++;
Itv_var("counter_k")=k;
//Displaying the number of people by the Captioner in the Monitor
DoReactStr("CAM","M","CLEAR_SUBTITLES","title_id<L>"); //M - Number of Camera L - Number of Captioner
DoReactStr("CAM","M","ADD_SUBTITLES","command<Number of people (entering/exiting): "+i+" / "+k+"\r>,page<BEGIN>,title_id<L>"); //M, L - the same
}
//Null the counter on Macro (the Macro must be created in Axxon PSIM beforehand)
if (Event.SourceType == "MACRO" && Event.SourceId == "P" && Event.Action == "RUN") //P - Number of Macro
{
Itv_var("counter_i")=0;
Itv_var("counter_k")=0;
i=0;
k=0;
//Displaying number of people by the Captioner in the Monitor
DoReactStr("CAM","M","CLEAR_SUBTITLES","title_id<L>"); //M - Number of Camera L - Number of Captioner
DoReactStr("CAM","M","ADD_SUBTITLES","command<Number of people (entering/exiting): "+i+" / "+k+"\r>,page<BEGIN>,title_id<L>"); //M, L - the same
}
As a result, when the corresponding camera is displayed in the Monitor, a text message about the number of entered and exited people will be superimposed on the video image.
Note
When you use the page<BEGIN> and page<END> parameters, the corresponding fields of the captions database are filled in. This enables data search using the Captions search interface object.
You can configure the font, color and position of text on the settings panel of the Captioner object (see Configuring captions display on a video image).
To null people counter, you must first create the Macro object on the Programming tab. You can change the name of the Macro object, for example "Null people counter".
You can run the macro to null people counter either manually from the main menu of Axxon PSIM or automatically at any specified time (for this, use the Events table on the settings panel of the Macro object on which you must specify the previously configured Time schedule object). For more information about the use of the Macro and Time schedule objects, see Administrator's Guide.
Example 3. Displaying camera on the monitor by clicking the button on the control panel
The following example is valid only for cameras in configuration of which there is a PTZ control panel. When configuring Video surveillance monitor, select the Go to preset action with 1,2,3...,0 parameters for ten joystick buttons (see Assigning commands to joystick buttons using the Monitor section of Installing and configuring security system components guide).
Example. When the button is clicked on the control panel, display the corresponding camera in the active Monitor. The script must be triggered by a timer with ID=1.
Note
You must create and configure the Timer object beforehand and set the current year. For detailed information on configuring the Timer object, see Creating and configuring the Timer object.
After each button click on the control panel wait for two seconds until clicking another button. If there is no button click, then the camera with dialed number must be displayed.
if (Event.SourceType=="TIMER" && Event.SourceId=="1" && Event.Action=="TRIGGER")
{
mon="1";
DebugLogString("on monitor "+ Itv_var("cam"));
DoReactStr("MONITOR",mon,"ACTIVATE_CAM","cam<"+Itv_var("cam")+">");
Itv_var("cam")="";
}
if (Event.GetParam("source_type")=="TELEMETRY" && Event.GetParam("action")=="GO_PRESET")
{
DoReactStr("TIMER","1","START","bound<2>");
var key=Event.GetParam("param4_val");
DebugLogString("Key:"+key);
Itv_var("cam")=Itv_var("cam")+key;
DebugLogString(Itv_var("cam"));
}
Example 4. Superimposing captions
On Macro 1, display the text
"NNN
Titles"
(with line break) over the video image of camera 1 using captioner 1. On Macro 2, disable the display of this text.
if (Event.SourceType == "MACRO" && Event.SourceId == "1" && Event.Action == "RUN")
{
DoReactStr("MONITOR","1","SET_TITLES","titles<NNN \r Titles>,cam<1>,title_id<1>");
}
if (Event.SourceType == "MACRO" && Event.SourceId == "2" && Event.Action == "RUN")
{
DoReactStr("MONITOR","1","CLEAR_TITLES","cam<1>,title_id<1>");
}
Example 5. Displaying a video camera with a stream of the selected type in the Video surveillance monitor
On macro command, display a video camera with a stream of the selected type or with the required stream ID on Monitor 2.
if (Event.SourceType == "MACRO" && Event.SourceId == "1" && Event.Action == "RUN") //by stream type
{
DoReactStr("MONITOR","2","REMOVE","cam<5>");
DoReactStr("MONITOR","2","ADD_SHOW","cam<5>,stream_id<stream_client_flag>");
}
if (Event.SourceType == "MACRO" && Event.SourceId == "2" && Event.Action == "RUN") //by stream type
{
DoReactStr("MONITOR","2","REMOVE","cam<5>");
DoReactStr("MONITOR","2","ADD_SHOW","cam<5>,stream_id<stream_analytics_flag>");
}
if (Event.SourceType == "MACRO" && Event.SourceId == "3" && Event.Action == "RUN") //by stream type
{
DoReactStr("MONITOR","2","REMOVE","cam<5>");
DoReactStr("MONITOR","2","ADD_SHOW","cam<5>,stream_id<stream_archive_flag>");
}
if (Event.SourceType == "MACRO" && Event.SourceId == "4" && Event.Action == "RUN") //by stream type
{
DoReactStr("MONITOR","2","REMOVE","cam<5>");
DoReactStr("MONITOR","2","ADD_SHOW","cam<5>,stream_id<stream_alarm_flag>");
}
if (Event.SourceType == "MACRO" && Event.SourceId == "5" && Event.Action == "RUN") //by stream ID
{
DoReactStr("MONITOR","2","REMOVE","cam<5>");
DoReactStr("MONITOR","2","ADD_SHOW","cam<5>,stream_id<5.1>");
}
