SVE (SmartVision Engine)
SVE (SmartVision Engine) is a camera management box foundational service platform that includes an application development framework for intelligent vision computing terminal devices, intelligent vision terminal device configuration management, application runtime services, and lifecycle management functions. AidLux is an innovative integrated operating system built on ARM hardware, bridging Android/HarmonyOS and Linux system environments. SmartVision runs on the AidLux system, leveraging the AI application runtime underlying SDK support provided by the AidLux platform, aiming to achieve defect detection on target objects and delivering a comprehensive defect detection solution for users.
System Configuration
Network
Network Configuration
The network configuration page is used to configure the IPv4 address of the camera's wired network port (eth0). The default is a static IP address (192.168.1.123/24).
Display
To be added.
Storage
Device Maintenance
The device maintenance page is mainly for configuring device login information and local cache settings. Here you can modify the SVE software login username and password, as well as configure the local cache retention period, system reserved space, and over-limit processing methods. System reserved space is the threshold at which, when remaining system space reaches the set value, the system reports an alarm and processes according to the configured over-limit handling method.
Video Playback
The video playback page mainly stores video file information recorded in "Camera Configuration." You can manage deletions by selecting and clicking batch delete.
Common Tools
Device Overview
💡Tip
SVE Page or Browser Closure Limitation: Closing the SVE page or browser may cause the camera status in the Device Overview to be inconsistent with the actual status.
For example: if cam0 is opened in Camera Configuration, the Device Overview shows cam0's status as Open. After closing and reopening the browser, even though the camera has not been opened elsewhere, the Device Overview still shows the camera status as Open.
The Device Overview mainly introduces camera-related parameter information, such as SoC model, MAC address, IP address, OS information, camera information, camera status, running tasks, etc.
- Device Overview — Main Parameters
| Parameter | Description |
|---|---|
| SoC Model | Displays the camera's chip model |
| MAC Address | Displays the MAC address of the camera's network ports. Shows both wired (eth0) and wireless (wlan0) if both are connected |
| IP Address | Displays the IP address of the camera's network ports. Shows both wired (eth0) and wireless (wlan0) if both are connected |
| OS Information | Displays the ROM version flashed on the camera and the tuning mode used by each camera |
| Camera Information | Displays the models of the main camera and sub-camera lenses |
| Camera Status | Displays the running status of the main camera and sub-cameras |

Task Management
The Task Management page mainly displays the camera's existing AI application list. By default, "Segmentation" and "Image Capture" examples are installed. Users can also add other applications as needed. On this page, you can manage all applications: preview, start/stop, configure, view logs, delete, etc.

Run and Preview Built-in Applications
💡Tip
Multi-Terminal Imaging Preview Limitation: Running different cameras simultaneously across multiple terminals is not supported.
For example: Browser terminal 1 previews cam0, browser terminal 2 previews cam1, browser terminal 3 previews cam2.
By default, "Segmentation" and "Image Capture" examples are installed in the application list. Take the "Segmentation" app as an example to run and preview inference results.
- Click the Start/Stop App button in the list to run the example application.
Click the Preview button to view the running effect.
After returning to the "Application List" page, click the Enter Imaging Settings button to configure algorithm settings and result processing settings.

System Monitoring
System Monitoring consists of two pages: "Alarm Information" and "Resource Monitoring".
Alarm Information
The Alarm Information page primarily records SVE alarm messages. Alarms are classified into five levels: "Critical", "Severe", "Major", "Minor", and "General", with different levels distinguished by different color markers. Each alarm records detailed information including severity level, event timestamp, event type, and event content, helping users quickly and accurately locate issues.
Resource Monitoring
The Resource Monitoring page primarily records device runtime information such as CPU, GPU, NPU, Memory, Storage, and Network (eth0/wlan0), enabling real-time monitoring of device operating status. Monitoring can be controlled via the "Stop/Start" button, and page data display can be adjusted via the "Data Display Interval" option — currently supporting 3-minute and 5-minute data intervals.
