Unboxing and Power On
Start by unpacking your reCamera. Inside the box, you should find:
- reCamera
- Type-C Cable
- Ethernet Cable
Make sure all parts are included.
Simply power on the device with the type-C cable provided. When you see the green light is on, that means the reCamera is ready to connect to the world.
Light Indicators Status:
| LED(color) | Status | Statement |
|---|---|---|
| LED1 - Green | ON | Power On |
| LED2 - Red | Flashing | CPU Working(user define) |
| LED3 - Blue | Flashing | eMMC Reading/Writing |
Network Connection
There are three methods to connect the reCamera to your network:
Method 1: USB cable
Wired Network Configuration via USB cable
Connect the USB cable from reCamera to your PC, you can then visit 192.168.42.1 to view the loading page for reCamera.
If you have reCamera with wireless function, we recommend to set up Wi-Fi connection. Only 2002w version will have the Wi-Fi Selection UI.
If you encounter any problems, please view the network troubleshoot.
Method 2: Ethernet
Ethernet Port Network Configuration
If you would like use ethernet port, you can use the cable in the box to connect to your router. Note, this is not a POE (Power over Ethernet). You still need the type-c to power on the device. You can unscrew the back of the camera and connect through the port.
Once connected, you can find the IP of reCamera on your router backend, then visit the website and Node-RED platform.
Method 3: AP mode (only available with 2002w versions)
Wireless Network Configuration in AP mode
When power-on, reCamera will turn on the Access Point(AP) for you to change the network preference. Open your phone or laptop's Wi-Fi list, you should be able to see a Wi-Fi name called reCamera_******.
The naming system is "recamera_" + the last six digits of the mac address on this device.
Default password is 12345678.
Connect to this AP, and a website should automatically pop out for you. If not, you can always type 192.168.16.1 in your browser to visit the page. Then you can select which wifi you want the reCamera to connect to. If you have more than one reCamera, you can refer to the Device Management to find out which one is which.
Basic Webs Access
Once you have connected the reCamera to your network, you can visit the website interface for reCamera by accessing the ip adress in the browser.
- USB connection IP: 192.168.42.1
- Wi-Fi or Ethernet connection IP: Use
ifconfigto find out or check with your router network management.

Please check your device OS version. There is a major upgrade between version 0.1.3 and 0.1.4. For smoother user-experience, we recommand upgrade to 0.1.5 and above. Please go to Sidebar -> System -> Software Update to check the software version, and apply and install the latest version of the OS. Update instruction please refer to OTA upgrade guideline.
OTA Upgrade from 0.1.3 to latest version
If you got the first batch of reCamera, you can upgrade the OS to the latest version following this instruction.
Step 1: Open the website and navigate to Sidebar -> System -> Software Update
Step 2: Check your OS version, and click Check and Apply.
Step 3: Wait for few minutes to update the system.
Step 4: Restart the device and refresh the website.
Step 5: You will enter the loading page to change the password.Now you can experience the newest version reCamera with Node-RED dashboard by following this downloading instruction.
Access reCamera preview dashboard
By integrated device with Node-RED, We provided a build-in dashboard UI example where you can preview the video stream, change the desire models. You can freely twist and integrate with your own application.
If your OS version is 0.1.5 or above OS version, the preview dashboard would be shown once you login in.
If you upgrade the OS by yourself, you can download the dashboard jsonflow from Sensecraft AI
Step 1. After upgrade finished, access the web either by 42.1 or network IP, then click Download dashborad flow
Step 2. Navigate to Sensecraft AI platform, select the first official Dashboard Demo and click Clone. Login is needed for this website.
Step 3. Select the connection method for your device.
Step 4. Then the Node-RED workspace with the pre-built flow would be shown.
Step 5. Click Deploy and check the flow is start already, then click dashboard, that dashboard would be shown.
Make sure to check the flow is started or not. Sometimes importing a flow will not automatically start the flow, thus dashboard will be empty.
Succeed!
Step 6. You can adjust the threshold of IoU and Confidence to get a more accurate result.
- IoU=0,Confidence=0:
- IoU=25,Confidence=33:
Quick understanding to flow:
In this example flow we built a demo of counting numbers of desired object such as Person, Cat, Dog, and Bottle with a Counting Selection drop down list.
By changing the function nodes in the flow, you are able to add more object to be counted, or completely change this function to some other computer vision applications.
You can view what kind of objects can be detected by viewing the model node.
Feel free to twist and play with flow in any way you want. Just be careful do not put too many debug nodes or preview nodes after the model nodes, as printing out multiple result from AI model will comsume CPU and cause the device crashing.
Computer Vision Model
For these provided workflow, YOLO11n detection model is selected by default, which is the latest computer vision model for real-time object detection model. You can also replace it with other models in the node. If you want to see what other models are available, you can refer to this wiki.
Intersection over Union (IoU): IoU is a metric used to evaluate the overlap between the predicted bounding box and the ground truth bounding box. It is calculated as the ratio of the intersection area of the two boxes to the union area of the two boxes. The value of IoU is typically in the range from 0 to 1. We standardized it to a scale of 0 - 100, an IoU value of 0 represents no overlap between the predicted box and the ground - truth box. A value of 100 indicates a perfect match, meaning the two boxes completely overlap.
Confidence: Confidence in the YOLO model represents the probability that a predicted bounding box contains an object and how accurate the prediction is. It is a value between 0 and 100.0
Customized your dashboard and share to Community
We encourage users to share the dashboards they develop and create in the community. We have created a folder on GitHub. We hope that everyone will share their dashboards there by pull request, and we will organize and display them. Here we will take adding a fill light function to the dashboard as an example to simply add a node and control reCamera.
Step 1. Drag the button group node to the workspace. and edit it by the following setting.
Step 2. Add a new ui-group config node named "Control Button", then save it.
Step 3. Go to the dashboard 2.0, and place the control button frame under the model selection.
Step 4. Deploy the flow and go to dashboard.
Demo:
Step 5: Don't forget to export json file of the flow and share it to the our github.
Port List
The following lists the ports used by reCamera:
- Port 22: Utilized for remote SSH login and is open.
- Port 53: Associated with DNS domain name resolution and is essential for web redirection. It is open by default.
- Port 80: Serves as the web dashboard interface for HTTP display of the Node-RED Application.
- Port 554: Employed for RTSP video streaming.
- Port 9090: Intended for web terminal access, which requires a password for login.
- Port 1880: Dedicated to Node-RED operations.
Factory Reset
If you would like to reset the device such as forgetting your device's passcode, you can long pressing the User button and then connecting the device to power. When the red light of the device is constantly on instead of blinking, release the User button.
This will delete user information, including applications you have developed, or any local storage image and video. Please operate with caution.
If you want to restore the firmware of your device to a specific version, please visit os version control
Multi Devices Management
If you have more than one reCamera, you can distinguish them by the mac address or S/N number on the back of the device.
Or, once you connect the device to your laptop through USB or AP, you can view the mac address by using the following command
ifconfig wlan0
Camera Orientation
The default camera view orientation is like the image below where type-c is facing down. Please be awared that other orientation might effect the accuracy of model based on how you trained the detection model.
