SD Card Related Lights
If both IR LEDs are ON, and/or the IR filter clicks, there is an issue with the SD card seating or formatting.
- If the SD card is accessible (dome cameras only) power down the camera, carefully reseat the SD card, and power back on.
- Contact Support if reseating doesn't resolve the issue, or it is a different device model.
Troubleshooting
Below is a list of steps to take if the cameras cannot be pinged.
- Unplug the device and plug it back in.
- Check all cables, ports, and switches.
- Check your network to see if the required ports are open.
- Check to see if you have the most up-to-date browser or mobile app.
- Open a support ticket with Rhombus.
