DualCam 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. Rear 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. The rear camera camgetver failed. |

- 5 – 1920x1080
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
camreq:1,<file source>,<domain>,<port>,<resolution>
Upload with domain, port, and resolution provided by a request. Example: camreq:1,1,192.168.1.1,12345,4
