Technical Requirements to Use CareerFairy
In this article, we will go over the fundamentals of technical requirements for event hosting.
Your attendees will be able to join your events on all major browsers including Google Chrome, Safari, Microsoft Edge, Mozilla Firefox, and Opera.
As a presenter, we strongly recommend you to use Google Chrome (always the latest version if possible). However, it is also possible to use Mozilla Firefox, Opera, Safari 12.1+, and Microsoft Edge 79+.
We really encourage you to use Chrome as a presenter though. Indeed, Chrome assures that the quality of the stream that you send out stays stable thanks to a technology called "Simulcast". It ensures overall stability to carry out your session, without any resolution or connectivity issues.
CareerFairy will detect if you're not using a supported browser like Chrome, Safari, Edge, or Opera. You will be presented with screen bellow
You must use a desktop/laptop computer to share your webcam and screen. The same goes for anyone that you invite as a speaker to share their screen, webcam, or audio.
CareerFairy is not optimized to work on mobile/tablet devices including iPhone, iPad and Android devices, but you can still connect through such a device if not desktop alternative is available. Some features might not be usable from a mobile device.
A minimum of 350kbs per downloaded/uploaded stream is necessary to join the room.
As a presenter, we recommend 5Mbps upstream for optimal results.
As an attendee, we recommend 5Mps downstream for an optimal experience.
CareerFairy will downgrade your video quality and give priority to the audio if you don't have enough bandwidth.
CareerFairy Tip 👉 Run a speed test to check your bandwidth.
This is a test from our offices, we have a pretty good download speed. Our upload speed is good but not incredible, enough to send a good video stream.
Your connection speed is not the only factor**. You have to also look for connection stability aka the number of people connected to that same connection. The connection stability will impact the number of packets lost during a live session. Therefore, try to use Ethernet over Wifi and ask your team to not saturate the network.
CareerFairy works with WebRTC which is a rather new technology that might require some network configuration within larger companies with secured firewalls.
Here are the items you will need to check with your IT department:
Open TCP ports 80; 443; 3433; 4700 - 5000; 5668; 5669; 6080; 6443; 8667; 9591; 9593; 9601; 9667; 30011 - 30013 (for RTMP converter)
Whitelist the following domains:
.agora.io
.edge.agora.io
.sd-rtn.com
.edge.sd-rtn.com
.edge.agora.io
.edge.sd-rtn.com
web-1.ap.sd-rtn.com
web-2.ap.sd-rtn.com
ap-web-1.agora.io
ap-web-2.agora.io
webcollector-rtm.agora.io
logservice-rtm.agora.io
rtm.statscollector.sd-rtn.com
rtm.logservice.sd-rtn.com
Allow all connections through the secure websockets protocol (WSS).
Open UDP port 3478; 4700 - 5000
UDP is highly recommended over TCP for better quality audio and video. The protocol favors timeliness over reliability which is consistent with the human perceptive preferences; where we can fill in gaps but are sensitive to time-based delays.
Emails delivery
We recommend that your email provider or email management system authorizes the below domain names to ensure the delivery of emails being sent by CareerFairy:
mail.careerfairy.io
careerfairy.io
Once you're done with the settings you should be good to go! In case you run into any issues, here are some tips to troubleshoot:
If you cannot connect to your or hear the event: Try connecting to an alternative network. University and corporate networks in particular can have restrictive security settings. You can try joining through your phone's 4G LTE connection.
If the problem persists ask your IT to unblock web sockets, the 443 ports for video streaming and the WebRTC protocol. See section above "Firewall settings".
CareerFairy Tip 👉 Pause your Google Drive sync or any other bandwidth-consuming apps during your event. 😉
