Connect

Connect(BSTR ip, BSTR login, BSTR password, BSTR arch_password, long param, long param) set up a connection to the Server/Video Gate/Backup Archive.

• BSTR ip – IP address of the Video server;
• BSTR login – login to connect to the Server (can be blank);
• BSTR password – password to set up a connection to the Video server (can be blank);

• BSTR arch_password – password to access the archive (i.e. admin password,  can be blank);

• long param – Server role. The parameter is mandatory.
  
  • 0 – video server;
  • 1 – backup archive;

  • 2 – videogate;

• long port – port to connect Video server.
  

  • if 0, 1 or 2 are passed, the connection is established with port 900, 901 or 902 correspondingly;

  • if 100 is passed, the connection is with port 10504;

  • if any onter value passed, the connection is with port number "port + 20000". For example, if port=900, the connection is established with server port 20900.

The connection to Server is set up asynchronously.

ShowCam

ShowCam(long cam_id, long compress, long show) shows/hides camera on the monitor.

• long cam_id – camera ID
• long compress – level of video compression 0-5 (for local camera =0). If set to -1, video stream is displayed directly from the camera without compression.
• long show – checkbox: show/hide camera (1/0)

DoReactMonitor

DoReactMonitor(BSTR react_string) – control over the monitor/cameras

• BSTR react_string – reaction string view

How to create react_string:

react_string =   "MONITOR||ARCH_FRAME_TIME|cam<3>,date<dd-mm-yy>,time<hh:mm:ss>";
CamMonitor1->DoReactMonitor(react_string);

The result of calling the function with the parameter: camera 3 will be in the archive mode and the archive will be positioned to date «dd-mm-yy» and time «hh:mm:ss» (date and time are to be set in this format only).

The mode parameter takes the following values:

0 – video gate if it's specified (otherwise, video server).

1 – video server.

2 – long-time archive.

“MONITOR|<id ignored>|ARCH_FRAME_TIME|...”

DoReactMonitor(“MONITOR||ARCH_FRAME_TIME|cam<3>,date<02-10 05>,time<12:12:22.345>

Example. Show 2nd stream from camera 14 on Monitor 1:

"MONITOR|1|ADD_CAM|cam<14>,cam_id<14>,compress<1>,stream_id<14.2>"

RemoveAllCams

RemoveAllCams() : long – remove all cameras from the monitor

IsConnected

IsConnected() : boolean – method shows if the Video server is connected or disconnected.

GetCurIp

GetCurIp() : BSTR – returns the IP address of Server specified when calling Connect.

SendRawMessage

SendRawMessage(BSTR msg) – sends the command to be executed to Video server.

• BSTR msg – command string view

How to call a function:

m_Cam.SendRawMessage("CAM|1|REC");

m_Cam.SendRawMessage("CAM|1|REC_STOP");

m_Cam.SendRawMessage("CAM|1|ARM");

m_Cam.SendRawMessage("CAM|1|DISARM");

Disconnect

Disconnect() – disconnect from the Video server. 

SetCallBackOptions

SetCallBackOptions(int cam_id, int options) – sets parameters of getting video from camera.

• int cam_id – camera ID (number).
• int options – options. The possible values of the options parameter are:
• WithoutVideoFrame = 0x00 – do not send frames from the video module.
• WithVideoFrame = 0x01 – send frames from the video module.
• WithExtendedParams = 0x02 – get frames with extended parameters (time, fps, subtitles).
• WithInformationLayout = 0x04 – display video in the window with control elements (context menu).
• WithCompressedData = 0x08 – display video in the native format without decompression (if any).

• WithoutDecode = 0x10 – disable video decoding on the server.
• WithoutSubtitles=0x20 – disable subtitles.

SetParam

SetParam(BSTR param_name, BSTR param_value) - sets the number of camera windows in CamMonitor.

• BSTR param_name - a string representation of the length or width.
• BSTR param_value - the number of camera windows.

How to call a function:

m_cam.SetParam("monitor_ch", m_NH);
m_cam.SetParam("monitor_cw", m_NW);
