Troubleshooting

This document contains troubleshoothing advices for some issues you can encounter.

The received frame rate of a device is lower than its configured frame rate

Orbbec

If you are using Orbbec Femto Megas, make sure nothing else on the network is actively streaming data from the camera. These devices can stream to multiple softwares and computers but they are not able to do so while keeping an optimal send rate.

If no one else than you uses the network and the received rate is still to low, make sure you are not saturating your network’s bandwidth. At their maximum throughput (1024x1024 at 15fps), without color, the Orbbec Femto Mega can use 253 Mibps of bandwitdth. This means that a single Orbbec can saturate a 200 Mibps link and that adding another camera to the network will further degrade performances. Make sure to use a link of at least 1Gibps if you have a small amount of cameras. It is also possible to use many 1Gibps networks if the server on which Carto runs has multiple network interfaces. If you can’t use a network with more bandwidth, try reducing the resolution or the framerate of your cameras.

Hesai

If you are using a Hesai, the target framerate in Carto assumes that the lidar is configured at 1200 rpm. If the lidar is turning at 600 rpm you will have half the frame rate

My Orbbec cameras send at 0FPS after a while

We have notices that Orbbec cameras have a tendency to disconnect after a certain amount of time if they are not connected to a dedicated network. If your orbbec are connected to a busy network where other users or AV equipment generates traffic, try to create a dedicated network for them.
