DualCam Data Sending Parameters ID

DualCam RS232 camera support

DualCam camera support was introduced from firmware version 03.27.06.Rev.360. A new RS232 mode "DualCam" was added with parameters for setting control. The details of the RS232 mode parameter are provided in the table below.

Parameter name	Parameter ID	Parameter value
RS232 Mode	151	18

Configuration version 8.14.1.0 has to be used if configuration is being made in offline mode.

Camera Feature Settings Parameters ID

Once this mode is enabled, new tab “Camera Settings” appears on the left sidebar. This will contain the main parameters for configuring the camera settings The parameter IDs and values are provided in the table below. Once configuration is saved to device, these parameters are updated.

Video sending by trigger

Video sending by trigger camera scenario monitors the selected trigger (video sending trigger parameter) and captures video from front, rear or both cameras before and after the event (video duration before trigger and video duration after trigger parameters). If the previously captured video has not finished downloading, then a new video capture is skipped until the old one has been sent. When this scenario is triggered, high priority eventual record is generated with the value corresponding to what triggered the scenario. See the table below.

Parameter name	Parameter AVL ID	Parameter value
SOS trigger	499	0 - Server request
		1 - DIN1
		2 - DIN2
		3 - Crash

Image sending trigger

Added Image sending trigger option (works the same way as Video sending trigger just triggers image sending). Both front and rear images will be sent.

For selecting multiple options using SMS/GPRS commands, add values of every option and set that value for this parameter.

For example, to set DIN1 (2), Crash (8), and Unplug (128) scenarios as triggers, add their values (2 + 4 + 128 = 138) and set the sum as the parameter value

Parameter name	Parameter AVL ID	Parameter value
SOS trigger	499	0 - Server request
		1 - DIN1
		2 - DIN2
		3 - Crash
		4 - Towing
		5 - Idling
		6 - Geofence
		7 - Unplug
		8 - Green Driving

Camera request command

A new camera request has been added, which allows the server to request files from a camera. The format is as provided below in the table:

Command	Arguments	Explanation
camreq:	<file_type>,<file_source>,<timestamp>,<duration> ,<domain>,<port>	Captures appropriate file with the provided details. If the connection to server is opened, them files immediately become available for download. If not, then connection is tried to be made. If <domain> and <port> parameters are included, the device will send footage of the command to that address.

The arguments are as follows:

• <file_type>
  • 0 - Video
  • 1 - Photo
• <file_source>
  • 1 - Front camera
  • 2 - Rear camera
  • 3 - Both cameras
• <timestamp>
  • Unix timestamps in decimal (not required for photo download)
• <duration>
  • Video duration in seconds from provided timestamps (not required for photo download), (max 30 sec)

Structure examples:

camreq:<file type>,<file source>(if video, add ",<timestamp>,<duration>)

However, if there is a need to send to the specific server without configuring, you can add two extra parameters. The complete structure:

camreq:<file type>,<file source>(if video, add ",<timestamp>,<duration>),<domain>,port

For example: camreq:0,1,1624960616,5,212.59.13.226,7160
