Hi, there!
In order to solve this issue, you would need to check every camera’s properties / video settings and test your own scenarios. However, according to the below specifications:
VCN540
Performance Specifications
Table 1 describes the performance specifications.Table 1 Performance specifications
|
Item
| Specification
|
Device access and video storage
| Supports a maximum of 64 video access channels or 320 Mbit/s video access bandwidth.
|
Video forwarding
| Supports a maximum of 128 video forwarding channels or 320 Mbit/s video forwarding bandwidth.
|
Video playback and download
| Supports a maximum of 32 video playback and download channels or 320 Mbit/s video playback and download bandwidth.
|
Ingress and egress bandwidth
| The ingress bandwidth does not exceed 320 Mbit/s.
The egress bandwidth does not exceed 320 Mbit/s.
NOTE:
· If cameras are connected through the GB/T 28181 or DHSDK protocol, both the ingress bandwidth and egress bandwidth do not exceed 256 Mbit/s.
· In the cluster or external domain connection scenario, the ingress bandwidth and egress bandwidth of the master server do not exceed 256 Mbit/s separately.
