I have a problem with my Dahua DH-XVR4108HS-X1 setup. I have had this setup working for 3-4 years now but suddenly f my Dvr has lost some configuration information. All four cameras show up on screen. I need to set up the ptz camera again. The PTZ camera is an Airspace Sam -4048. On screen I can see the address is 1 and the baud rate is 2400. anyone know which protocol i should use for this camera? any info would be greatly appreciated
