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 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. |
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
