Dedicated to Provision of Long Term Stable Running IoT Devices
Read before starting: Each time we can only set 1pcs unit to send data to GPRS Server. Car Tracker with Camera firmware should be V118 version or higher than V118 version.
Then set Port forwarding in your router accordingly:
Check if data coming on GPRS-server, if yes, we can start testing VT200-L car tracker with camera. 4. Connect VT200-L with Camera.
Important: Please connect the GPS Tracker with external power supply firstly, then connect the camera with tracker via RS232 Port secondly, to prevent the camera from being burned out due to excessive voltage instantaneously.
4.1 After connecting the wires, you can set the serial port to connect to the external device through the Parameter Editor (version V1.8 or later) or SMS command: 1) Open Parameter Editor: select “Camera”.
Configuration by SMS command 252, Example: 0000,252,1,3
4.2 After configuring the serial port, you can set the camera parameters through the parameter editor or SMS commands. 1) Open Parameter Editor, select the corresponding resolution and the time interval for uploading photos, check the “GPRS events for taking pictures by default”.
2) Send SMS to configure camera parameters: Set the resolution of the camera (1: 160*128, 2: 320*240, 3: 640*480) through SMS command 260, for example, set the resolution of 1# camera to 320*240, you can send : 0000,260,1,2
Set the upload time interval of the camera through SMS command 261, for example, set the time interval of 1# camera to take pictures regularly to 1 minute, you can send: 0000,261,1,1 4.3 Take pictures on demand
Send 262 commands to take pictures, after the device uploads the photo event to the platform, the platform sends 265 commands to read the photo data. After the device uploads the complete photo data, the platform can issue the 264 command to delete the photo (VT200 series devices support up to 128 photo storage, and the earliest photo will be overwritten when the photo exceeds 128) 1) Send GPRS command to take pictures via GPRS server; for example, to take pictures for camera 1#, you can send as below screenshot: Select XTL_PRO, fill in 262, fill in 1, choose ASCII Data, select show in Hex, finally click send.
Then we can see ok on the data, 221021023009C1E34.jpg is the photo name.
4.4 Read photos
The photo can only be read through the platform (GPRS) by sending the 265 command. For example, to read the picture 221021023009C1E34.jpg, you can send on GPRS server as below:
As shown above, the garbled code is reading the photo. When you see that the garbled code is not displayed in the GPRS SERVER, it means that the photo reading completed. Then you can search 221021023009C1E34.jpg to find the photo in your laptop. 4.5 Read photo list and delete photos 1) The photo list can only be read by sending 263 commands through the platform (GPRS). The device can upload a maximum of 50 photo names in one package of data. If the data is exceeded, it will be uploaded in multiple packages. The VT200 series Tracker with Camera supports a maximum of 128 photo storage. For example, to read the list of photos stored in the device, you can send on GPRS server as below: The contents include jpg is photo name.
