Check Bandwidth

Note
 서비스 구동 전, PostSd - AWS간, PreSd – Camera간, PreSd/PostSd – VPd간 Network 속도가 서비스에 영향이 없는지 대역폭 확인이 필요하다

 Before starting the service, it is necessary to check the bandwidth to ensure that the network speed does not affect the service between PostSD and AWS, between PreSD and the Camera, and between PreSD / PostSD and the VPD’s.

Bandwidth Check List

  •   PostSd PostSD to AWS

  •   PreSd PreSD to Camerathe Cameras

  •   PreSd PreSD /PostSd PostSD to VPdthe VPD’s

 

PostSd to AWS

Note
4DLive 시스템 사용 시, 원활한 비디오 데이터 송수신 하기 위해 AWS 4DRS와 PostSd간의 대역폭 체크를 특정 프로그램을 통하여 사전에 수행한다

When using the 4DLive system, check the bandwidth from the 4DRS between the AWS and PostSD are performed in advance through a specific program in order to smoothly transmit and receive video data.

4DDM 프로그램 중간 상단 측, Log 버튼을 통해 PreSd 및 PostSd와 VPd 간 Bandwidth를 확인할 수 있다. PreSd 나 PostSd는 각각 하나씩 or All 중 선택이 가능하지만, VPd는 All으로만 설정이 가능하다.

You can check the bandwidth between the PreSD and PostSD and the VPD’s on the Log button which is located at the top of the middle of the 4DDM program. PreSD and PostSD can be selected either one or All, but VPD’s can only be set to “All”
