The information on this page addresses the communication methods used by EchoVideo capture devices. These devices need to communicate externally with the EchoVideo active learning platform as well as internally to other servers via the local area network (LAN).
NOTE: The information on this page applies to all capture devices except for Universal Capture, where DHCP and NTP do not apply; they are handled by the computer OS.
External Device Communication and Firewall Port Requirements
Capture devices require only two external communication ports; one to the EchoVideo server, and one to the default network time server.
If you use an internal time server, the external NTP server connection is not needed.
| Port Description | Default Port | Port Direction | Protocol |
|---|---|---|---|
| HTTPS (Secure Hypertext Transfer Protocol) Outbound required to EchoVideo server |
443 | outbound | TCP |
| NTP (Network Time Protocol) to *.pool.ntp.org (default EchoVideo time server) (If you use an internal time server, this does not apply.) |
123 | outbound | UDP |
| RTP (Real-time Transport Protocol) to Active Learning Streaming Servers (Applies only to LIVE streaming; see Port Configuration for LIVE Streaming for details.) |
64936-65535 | outbound | UDP |
Internal Network Device Communication Ports and Methods
Device communications through the internal network or LAN are defined in the below table.
| Port Description | Default Port | Port Direction | Protocol |
|---|---|---|---|
| DHCP (Dynamic Host Configuration Protocol) (Appliance may be set to static addressing later but requires DHCP initially.) |
67, 68 | both | UDP |
| DNS (Domain Name Service) | 53 | outbound | UDP |
| HTTPS (Secure Hypertext Transfer Protocol) (Optional, for device web interface access, including ad-hoc capture UI) |
443 | inbound | TCP |
| HTTP (Hypertext Transfer Protocol) (Optional, for device web interface access, including ad-hoc capture UI) |
80 | inbound | TCP |
| HTTP (Hypertext Transfer Protocol) (Applies only to LIVE streaming; see Port Configuration for LIVE Streaming for details.) |
80 | both | TCP |
| Internal NTP Time Server (if used) (If you use the default Echo NTP server, see table in section above.) |
123 | outbound | UDP |
