I cannot decrypt configFileExport.backup of DH-XVR5116HS with Bashis Python script . I tried with key nvr, xvr, dvr, sd, ipc, dahua, but not pass. With XVR5116HS is passed with key xvr, and passed with NVR4104 and key nvr.
For DH-XVR5116HS I have admin user/pass, but havent passwords for IP cameras
