Connect

Connect(BSTR ip, BSTR login, BSTR password, BSTR arch_password, long param, long port) sets a connection to the server/video gate/backup archive.

BSTR ip—IP address of the server.
BSTR login—login to connect to the server (can be blank).
BSTR password—password to set up a connection to the server (can be blank).
BSTR arch_password—password to access the archive (that is, admin password, can be blank).
long param—server role. The parameter is mandatory.
- 0—video server.
- 1—online archive.
- 2—video gate.
long port—port to connect to server.
- if 0, 1, or 2 are passed, the connection is established with the port 900, 901, or 902, correspondingly.
- if 100 is passed, the connection is to the port 10504.
- if any other value is passed, the connection is with the port number "port + 20000". For example, if port=900, the connection is established with server port 20900.

The connection to the server is set up asynchronously.

If login and password are not specified at the Connect() method call, all cameras are viewable in the control. If differentiation of permissions is important, this must be taken into account at the development stage.

ShowCam

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

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 this parameter: camera 3 is switched to the archive mode, and the archive is positioned to date "dd-mm-yy" and time "hh:mm:ss" (date and time must be set in this format only).

The mode parameter can take the following values:

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

1—video server.

2—backup archive.

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

Optionally, you can also specify positioning accuracy down to milliseconds, for example:

DoReactMonitor(“MONITOR||ARCH_FRAME_TIME|cam<3>,date<02-10-05>,time<12:12:22.345>,mode<1>")

Example. Show the second stream from camera 14 on monitor 1:

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

Exapmle. Set FPS = 1 when viewing archive from camera 11:

"MONITOR||CAM_PARAMS|cam<11>;arch_fps<1>"

Example. Get the coordinates of the fisheye camera 1 in the monitor (Monitor 1):

"MONITOR|1|GET_CAM_PARAMS|cam<1>"

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 the server specified when calling Connect.

SendRawMessage

SendRawMessage(BSTR msg)—send 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 to get 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, captions).
WithInformationLayout = 0x04—display video in the window with control elements (context menu).
WithCompressedData = 0x08—display video in the original format without decompression (if any).
WithoutDecode = 0x10—disable video decoding on the server.
WithoutSubtitles=0x20—disable subtitles.

The options parameter is formed in the same way as the parameters of the CamMonitor.ocx component (see CamMonitor.ocx parameters).

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);
