FAQ
| Question | Answer |
|---|---|
| 1、Does this include a camera? | Yes, it is a pure module and comes with a sensor |
| 2、Is the source code of the license plate recognition provided? | Source code is not provided |
| 3、Can it run at low power, with radar detecting a car and then waking it up for recognition? | No, it cannot be that fast; it needs to be powered on all the time, with power consumption of about 1W |
| 4、How long does it take to boot? | About 5s; with fast boot optimization it can be about 1s |
| 5、Can I configure the lens myself? With different focal lengths? | Yes, just choose the version without a lens. Please refer to the SKU pictures on the page for details |
| 6、What does the technical integration fee mean? | It means our technical team helps integrate it into your existing system |
| 7、Are there SDK development materials? | Yes, an HTTP interface document is provided: doc-258.html |
| 8、Can it recognize helmets and electric bicycles? | Yes, but the algorithm is charged separately |
| 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 connected via serial port, so it has nothing to do with the system |
| 11、Can it capture images while outputting the license plate recognition result? | Yes, it will automatically take a snapshot when a different license plate is recognized |
| 12、What are the resolution and frame rate? | The resolution is 3840x2160, the sub stream is 1280x720, and the frame rate is 25 |
| 13、Can the storage path of the automatic snapshot images be changed? | No, changing it requires modifying the program. The 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 existing product does not have this function; a development fee is required for separate customization |
| 16、Can it recognize vehicles entering and exiting? | The existing product does not have this function; a development fee is required for separate customization |
| 17、Can it be used to capture license plate photos on highways, for example an external trigger signal is given to the module when a vehicle passes by, and then it captures an image and recognizes the license plate? | Highway license plate recognition requires a high-speed license plate module. The current high-speed module uses the t40m38-oa0810, which is passively triggered to take photos and requires sending commands through the serial port |
| 18、So the module captures and recognizes the license plate after receiving the serial port command, and the recognition result is also transmitted through the serial port, right? What result will be returned if there are several vehicles in the frame at the same time? | Yes, the recognition result is also sent out through the serial port, and the results for several vehicles will be output cyclically |
| 19、Can the microphone interface be directly connected to a speaker? | The microphone interface is for connecting a microphone, not a speaker. A microphone is a pickup; only with a microphone connected will there be sound |
| 20、Can the USB 2.0 interface be used to transfer images? | This requires customization and is currently not supported. Generally, transmission can be done through 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 are the test statistics based on, and is there any actual measurement from a deployed project? | The recognition rate is 99%, based on high-speed capture, and there are actual measurements from deployed projects |
| 23、After the license plate recognition device is configured, to obtain the recognition results, do we use your client, or access the camera directly, or do we need to do some integration development? | Integration development is required. The license plate is transmitted through the serial port and socket |
| 24、How many mm is the lens? Can it be changed? | The warehouse ships a 2.8MM lens or a 4MM lens by default, randomly. It can be changed to a lens of other mm, but the price difference of the lens needs to be paid. Please contact customer service for the specific price difference |
| 25、What is the maximum vehicle speed supported? Can it be used on highways? How does it recognize at night on highways? | It supports up to 120-140 and can be used on highways. At night it needs fill light, the same as the surveillance cameras used on highways |
| 26、How much wide dynamic range? | Wide dynamic range is not supported off the shelf |
| 27、Do you have your own cloud service platform? | Yes (a test link is also available) |
