DashCam SMS commands

Camera firmware version

Additional SMS/GPRS command for cameras’ firmware checking. Since both cameras are separate, there are two versions returned.

Command	Arguments	Explanation
camgetver	None	Used to check firmware versions. Returns version in the format: V<major>.<minor>.<revision>. For example, V1.9.3. Because there are two cameras, two versions are returned. The complete response would look like this: Front camera V1.9.3. If there are problems reading the version or if the camera is not responding/connected, the return would be this: The front camera camgetver failed.

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
