RVC Camera – Camera Connection problems and solutions

Step 5: If the device is still not detected after the above steps, you need to check whether the Linux kernel parameter rp_filter has been modified. Open the command line terminal and enter:

cat /proc/sys/net/ipv4/conf/all/rp_filter

If the returned value is 1, the parameter needs to be changed to 0. Use the cd command to navigate to the scripts folder in the RVCManager installation directory, then run the set_rp_filter.sh script:

cd /opt/RVC/scripts

chmod +x set_rp_filter.sh sudo ./ set_rp_filter.sh

If the camera still cannot be detected after the above steps, please contact technical support.

2. How to determine and resolve camera IP address conflicts?

When the camera is connected to the computer through a switch, IP conflicts may occur. An IP conflict can cause the camera to appear in the device list but fail to function (e.g., unable to open the camera). Therefore, it is recommended to check the IP before connecting the camera through a switch. See the following steps:

① First, connect the camera directly to the computer, confirm it works normally, and record the network port IP.

② Disconnect the camera, connect the computer to the network, and use the ping command to check whether any device is occupying that IP.

③ If another device is using the IP, you can either change the IP address of the conflicting device or reconnect the camera directly and modify its IP address.

3. Failed to open the camera.

① First, open the device management pop-up window and check whether the device status is “occupied”. If the device is occupied, please release the occupation and search for the device again and connect.
