Check Bandwidth
| Note |
|---|
Before starting the service, it is necessary to check the bandwidth to ensure that the network speed does not affect the service between PostSd PostSD and AWS, between PreSd PreSD and the Camera, and between PreSd PreSD / PostSd PostSD and VPdthe 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 |
|---|
When using the 4DLive system, check the bandwidth checks from the 4DRS between the AWS 4DRS and PostSd PostSD are performed in advance through a specific program in order to smoothly transmit and receive video data. |

Step 2 In the path (for version 2,) enter 'iperf -s' (for version 3,) 'iperf3 -s'
Enter
Install iperf or iperf3 the same on your PostSd PostSD system
Step1 Copy the same file location as
(For version 2) Type 'iperf –c 10.82.7.214'
(For version 3) Type 'iperf3 -c 10.82.7.214'
If you enter it, you can check the bandwidth as shown on the left.
※ The usage method of iperf (version 2) and iperf3 (version 3) is different
※ iperf(version2) can check the speed without server mode
