To illustrate available fields of application of scripts in Jscript see the following examples which can be used to create additional functions in the system on the basis of the Script object.

...

Settings of the font, color and position of text is configured on the settings panel of the Captioner object.

Example 2. Visualisation of operating the People Counter detection in the Video Surveillance monitor

...

As a result the text message about number of entering and exiting people will be imposed on the video image while displaying the corresponding camera in the Video Surveillance monitor.

Settings of the font, Settings of the font, color and position of text is configured on the settings panel of the Captioner object (see the Configuring captions display on a video image section of the Administrator’s Guide document).

Previously create the Macro object on the Programming tab to null the counter of visitors. The name of the object can be changed to “Null of people counter” for ease of using.

Macro of setting to zero can be run manually by main menu of the Intellect software package or automatically in any specified time (use the Events table on the settings panel of the Macro object where the previously configured Time zone object is to be specified). Detailed information about using the Macro and Time zone objects is given in the Administrator's Administrator’s Guide document document).

Example 3. Setting the text for displaying on the map

It is possible to select the type of Text displaying while attaching object to the map (see Administrator Administrator’s Guide, the Attaching objects to the layers of interactive map section). Also the script on the JScript language can be used for changing the displayed text.

...

After each button click on the control panel wait for 2 seconds until clicking another button. If there is no button click, then the camera with dialed number is to be displayed.

if (Event.SourceType=="TIMER" && Event.SourceId=="1" && Event.Action=="TRIGGER")
{
  mon="1";
  DebugLogString("наon мониторmonitor "+ 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 5. Sending command to camera using the camera HTTPAPI

...

function DoPreset(preset)
{
    xmlhttp=new ActiveXObject("MSXML2.XMLHTTP");
    if(xmlhttp == null)
    {
           return;
    }
    xmlhttp.open("GET", "http://192.168.0.13/httpapi/SendPTZ?action=sendptz&PTZ_PRESETSET="+preset, false,"admin","1234");
 
    xmlhttp.send();
    DebugLogString(xmlhttp.status);
}
if (Event.SourceType == "MACRO" && Event.SourceId == "6" && Event.Action == "RUN") 
{
 DoPreset("85");
}
 
if (Event.SourceType == "MACRO" && Event.SourceId == "7" && Event.Action == "RUN") 
{
 DoPreset("86");
}

Example Example 6. Script for framing abandoned objects in live video

If the object tracking function is in use (see Creating and configuring the Timer object section of Administrator's Administrator’s Guide), then detected objects will be framed in video when viewing the archive. To frame abandoned objects in live video use the script aimed to frame an abandoned object when receiving alarm from VMDA detection tool:

if (Event.SourceType=="CAM_VMDA_DETECTOR")
{
 cam=GetObjectParentId("CAM_VMDA_DETECTOR",Event.SourceId,"CAM");
 if (Event.Action=="ALARM")
 {
   var x1,x2,y1,y2;
   x1=Event.GetParam("x");
   x2=Event.GetParam("w");
   y1=Event.GetParam("y");
   y2=Event.GetParam("h");
   x2=parseInt(x1)+parseInt(x2);
   y2=parseInt(y1)+parseInt(y2);
   DoReactStr("MONITOR","","SET_MARKRECT","cam<"+cam+">,color<255>,id<"+cam+">,x1<"+x1+">,x2<"+x2+">,y1<"+y1+">,y2<"+y2+">");
   DebugLogString("x1:"+x1+" x2:"+x2+" y1:"+y1+" y2:"+y2);
 }
 else
 {
   DoReactStr("MONITOR","","DEL_MARKRECT","cam<"+cam+">,id<"+cam+">");
 }
}

Example 7. Using START and STOP events for Failover

Objects from more than one main Server are not to be moved to the Backup Server. For this when moving objects from some main Server to the Backup Server all other Failover objects are to be disabled on this Backup Server.

if (Event.SourceType  == "FAILOVER" )
{
  if (Event.Action == "START") {action="DISABLE";}
  if (Event.Action == "STOP") {action="ENABLE";}
  id=Event.SourceId;
  msg=CreateMsg();
  msg.StringToMsg(GetObjectIds("FAILOVER"));
  var
  objCount=msg.GetParam("id.count");
    for (i=0;i<objCount;i++)
    {
     pid=msg.GetParam("id."+i);
  
     if (!(id==pid)) {
       DoReactStr("FAILOVER",pid,action,"");
     }
  } 
}

Example 8. Using the embedded visitors counter on Bosch FLEXIDOME IP dynamic 7000 VR IP camera

Upon reaching the number of visitors equal to 20 on the embedded visitors counter of the Bosch FLEXIDOME IP dynamic 7000 VR IP camera (with ID 1), call the macro 1.

n=20;
if(Event.SourceType == "CAM_IP_DETECTOR" && Event.SourceId=="1" && Event.Action == "DETECTED")
{
 v=Event.GetParam("param0").split(";")[1];
 if (parseInt(v.split(":")[1])==n)
 {
     DoReactStr("MACRO","1","RUN","");
 } 
}

Example 9. Sending e-mail with HTML markup

By macro 1, send a message with the attached files detected.png and found.jpg from the folder C:\\Pictures\\ to example@gmail.com. The message should be formatted as follows:

Face detected

if(Event.SourceType == "MACRO" && Event.SourceId=="1" &&Event.Action=="RUN")
{
var file1 = "detected.png";
var file2 = "found.jpg";
var file_folder = "C:\\Pictures\\";

var test_event = CreateMsg();
test_event.StringToMsg("MAIL_MESSAGE|1|SEND_RAW|cc<>,to<admin@axxonsoft.com>,objname<Mail message 1>,subject<>,parent_id<1>,flags<>,pack<>,name<Mail message 1>,from<example@gmail.com>,_marker<>");

test_event.SetParam("body","<html><body>\r\n<h3>Face found</h3>\r\n<table><tr>\r\n<td>Detected</td><td>Found in DB</td>\r\n</tr><tr>\r\n<td><img width='200' alt='image1' src='cid:"
+
file1
+
"'/></td>\r\n<td><img width='200' alt='image2' src='cid:"
+
file2
+
"'/></td>\r\n</tr><tr>\r\n<td>E-mail sent from Intellect</td>\r\n</tr></table>\r\n</body></html>");
test_event.SetParam("attachments",file_folder+file1+";" + file_folder+file2);
test_event.SetParam("is_body_html", 1);
DoReact(test_event);
}
