Issue Description

<Describe your issue / question / feature request / etc..>
My L515 was still working yesterday but suddenly I can't detect objects four meters away. I didn't change any settings, and the sensors didn't suffer any damage. I rebooted the firmware but nothing improved.Would you please tell me how did you solve this problem?Any help would be greatly appreciated.

Thanks.

Hi @xyxegle First, please try setting the Preset to Low Ambient Light. This setting uses maximum laser power like the Max Range setting does but takes account of low ambient lighting if the lighting level has reduced.

Under the Depth Visualization category of the options side-panel of the Viewer, also check that the Max Distance setting is at its default of '16'.

Thank you for your reply. I just tried it again. I found that the depth data returned to normal without adjusting the parameters.
I remember that I had been using it from last night until today. Finally, it overheated and the data became abnormal. Anyway, thank you very much for your careful reply to my question, and I hope RealSense can provide better sensors soon.

Thanks very much @xyxegle for the update - it's excellent to hear that your camera is operating normally.
