After I enable H.264 recording of an AXIS M7001 camera on two NVR servers, when I click test button on camera configuration page, NVR will return "MJPEG Test OK but MPEG-4 Failed when trying RTSP protocol. Why?

Applied Models:

  • NVR-104P
  • NVR-104V
  • VS-101P
  • VS-101V
  • VS-2008
  • VS-2012
  • VS-201P
  • VS-201V
  • VS-4016U-RP
  • VS-5012
  • VS-5020
  • VS-8024
  • VS-8024U-RP
  • VS-8032
  • VS-8032U-RP
  • VS-8040
  • VS-8040U-RP


When multiple NVRs send connection requests, AXIS M7001 cameras will sometimes return MSB_RET_HTTP_REQUEST_FAILED.

Please try to reboot AXIS M7001 to solve the issue. Otherwise, please make sure that AXIS M7001 camera is only connected by one NVR.
