Integration: Troubleshooting

Alarms not sending despite correct setup on NVR

On some models of Dahua devices it is required to have the user and pwd field populated when setting up the SMTP details.

Though SureView doesn't require this to be fulfilled, the DVR can error if they are not.

If you are unable to configure the DVR to send alarm emails, try populating the user and pwd fields with some data (anything - it's not being used) and retry.

"The audio codec in use is not currently supported"

Try a setting up the DVR with a different audio codec. Some are known not to work.

G711 should be a good one to try.

Additionally, the firmware should be upgraded to V3.210.0002.0. Dahua have advised that firmwares of lower versions have been known to experience audio issues.

Multiple Cameras Fail to Stream (User Already Logged In)

If you can only connect to one camera at a time then this is normally caused by the Dahua User being set to only authenticate for single camera streams. You will need to set the user in Dahua to be approved for "simultaneous camera streams" on the Dahua NVR

This may also present itself with the error "User Already Logged In".
