Device FAQ
| Question | Answer |
|---|---|
| 1、Does it come with a camera? | Yes, it is a pure module with a sensor |
| 2、Is the source code of license plate recognition provided? | The source code is not provided |
| 3、Can it be low power, with radar detecting a car and then waking it up for recognition? | No, it cannot respond that fast. It needs to stay powered on, with power consumption of about 1W |
| 4、How long does it take to boot? | About 15s. A faster boot time requires customization |
| 5、Can the lens be matched by myself? With different focal lengths? | Yes. The 209 module has a sensor but no lens, and the 269 has a lens. Please refer to the SKU image on the page for details |
| 6、What does the technical integration fee mean? | It means we provide technical help to integrate it into your existing system |
| 7、Is there SDK development material? | Yes, an HTTP API document is provided: In-site Docs Center |
| 8、Can it recognize helmets and e-bikes? | Yes, but the algorithm is charged extra |
| 9、Is the hardware source code open? | It is not open source |
| 10、Does the platform support LINUX 5.8? | This is a finished product with serial port integration, so it has nothing to do with the system |
| 11、Can it capture images while outputting license plate recognition results? | Yes, it will automatically capture an image when a different license plate is recognized |
| 12、What is the resolution and frame rate? | The resolution is 1920x1080, the sub stream is 1280x720, and the frame rate is 25 |
| 13、Can the storage path of automatically captured images be changed? | No, changing it requires modifying the program. Captured images are stored in the /media/snap folder of the system |
| 14、How fast can the vehicle speed be recognized? | Vehicle speed cannot be recognized |
| 15、Can it be set to capture only entering vehicles and not exiting vehicles? | The current product does not have this function. It requires a development fee for customization |
| 16、Can it recognize vehicles entering and exiting? | The current product does not have this function. It requires a development fee for customization |
| 17、Can it be used to capture license plate photos on highways? For example, when a vehicle passes by, an external trigger signal is given to the module to capture an image and then recognize the license plate | Highway license plate recognition requires a highway license plate module. The current highway module uses t40m38-oa0810, which is passively triggered to take pictures and requires sending commands through the serial port |
| 18、After a serial port command, the module can capture and recognize the license plate, right? Is the recognition result also transmitted through the serial port? If there are several vehicles in the frame at the same time, what result will be returned? | Yes, the recognition result is also sent out through the serial port, and multiple vehicles will be output cyclically |
| 19、Can the microphone interface be connected directly to a speaker? | The microphone interface is for connecting a microphone, not a speaker. A microphone is a pickup; only by connecting a microphone will there be sound |
| 20、Can the USB2.0 interface be used to transfer images? | This requires customization and is not currently supported. Images are generally transferred via network protocols or the serial port |
| 21、Is the network protocol through the RJ45 port? | There is an RJ45 port and network transmission is supported |
| 22、How high is the recognition rate, what scenario were the test results based on, and are there real deployed project measurements? | The recognition rate is 99%, based on highway capture, with real deployed project measurements |
| 23、After the license plate recognition device is configured, to get the recognition results, do we use your client, access the camera directly, or do we need to do some integration development? | Integration development is required. The license plate is transmitted via serial port and socket |
| 24、Does the tail cable have an RJ45 outlet? | Yes |
| 25、The camera sends data through the serial port. What is the default baud rate of the serial port? | 115200 |
| 26、Must this product be connected to the network to be used? | No, it can also be used without a network connection |
| 27、Do you have your own cloud service platform? | Yes. (There is also a test link) |
