How to IRL stream: the chain, and the three ways to build it
By Elan Harpaz · Published 2026-08-06
Going live from the street with no PC. What each of the five jobs does, and the three real rigs that do them, from a phone in your hand to a bonded backpack.
Your encoder tops out at 1080p60. A higher-end encoder would go further.

IRL streaming is a desk stream with the desk removed, and everything hard about it follows from that one change. A wired line is replaced by a cellular one that moves through buildings and crowds, so the parts list stops being about picture quality and starts being about what happens when the signal goes. Five jobs have to be covered, and they are worth naming in the order that decides whether the stream survives.
- The connection. One or more data lines, ideally on different carriers, because this is the part that fails.
- The encoder. A phone app or a dedicated box that turns the camera feed into a stream.
- The relay. Where you send that stream instead of sending it to the platform, so a lost signal is a BRB screen rather than an ended broadcast.
- The camera. Whatever the encoder can read, which on a phone build is the phone itself.
- Power. Enough of it that the rig outlasts the stream, and legal enough to fly with.
The three rigs that actually exist
| Phone rig | LiveU Solo | DIY belaBOX | |
|---|---|---|---|
| Encoder | Moblin or IRL Pro, free | LiveU Solo, $995 | Orange Pi 5 + belaBOX, $150 |
| Bonding | SRTLA in the app | LRT, built in | SRTLA, built in |
| Camera | The phone | Any clean HDMI source | Any clean HDMI source |
| Assembly | None | None | A board, a case, a flashed microSD |
| Tracked monthly | $25 data + $10 relay | $50 service + data | $25 data + $10 relay |
| Where it stops | One line, so one dead zone | Nothing, until the bill | You are the support line |
Start on the phone, and not as a compromise
The phone rig is the easiest IRL setup there is and it is a legitimate one. A modern phone is camera, encoder and modem in a single object, the apps are free, and the app encoders speak SRTLA to a relay, so you get the one thing that actually matters. What you do not get is a second pipe: one phone is one connection, and The 70% Headroom Rule budgets it at about 3.5 Mbps of usable upload, which is a 1080p30 tier and nothing above it. Stream on that for a month before you spend anything, because it tells you whether you like doing this at all.
The two dedicated paths, and the $845 between them
A LiveU Solo at $995 tracked is the least setup you can buy: HDMI in, bonding built in, power it on. A DIY belaBOX is $150 in parts and does the same job with SRTLA, at the cost of assembling a board, flashing a microSD, and being your own support when something is wrong at 11pm in a car park. That gap is $845 and the honest way to read it is as an hourly rate on your own evenings. Neither is more reliable in a way a viewer can see; the LiveU has a phone number and the belaBOX has a Discord.
The DIY path at $150 tracked. Free open-source firmware, HDMI in, and SRTLA bonding to your relay.
The turnkey path at $995 tracked plus a service line. Buy it when your time is worth more than the difference.
The reason to prefer a real modem over a hotspot: an ethernet port, so the encoder is wired to the radio rather than sharing a Wi-Fi hop with it.
Frequently asked
What do you need to IRL stream?
Five jobs, in this order of importance: a connection, something to encode the video, somewhere for that stream to land when the connection dies, a camera, and power. A modern phone can be the first four of those at once, which is why the cheapest real IRL rig is a phone, an app, and a data plan.
What is the easiest IRL streaming setup?
A phone running Moblin or IRL Pro into a relay, with a gimbal and a battery. Nothing to assemble, nothing to flash. The easiest dedicated rig is a LiveU Solo at $995 tracked, which bonds cellular out of the box; the cheapest is a DIY belaBOX, which trades a build weekend for about $845 of the difference.
What stream quality does this 1080p backpack build hold?
This 1080p backpack build holds 1080p60 on Twitch (standard), planned against a budget of about 5,600 kbps with the stream itself sitting near 4,200 kbps on the wire. That is a conservative planning figure with headroom built in, not a peak, so it is what the build should hold on an ordinary day rather than its best ever result.
How much upload speed does this 1080p backpack build need?
About 6.0 Mbps of sustained upload to run 1080p60 comfortably. That is the 4,200 kbps this build actually puts on the wire plus the headroom that stops a bitrate spike or a moment of packet loss from turning into a buffer. Planning at exactly the stream bitrate is how streams end up stuttering on connections that look fine on a speed test.
How much does this 1080p backpack build cost?
$1,375.12 in hardware as specified here, plus roughly $35 a month in running costs for the data plan, bonding, or relay this build depends on. Prices are tracked estimates rather than a live feed, so treat them as a planning number and check the retailer page before buying.
What is the bottleneck in this build?
What stops this build going a tier higher is the encoder. It tops out before the connection does, so a more capable encoder is the upgrade that matters. Naming the actual limit matters because the expensive upgrade people reach for first is usually not it.
How much mobile data does this 1080p backpack build use per hour?
Roughly 1.9 GB per hour at 4,200 kbps, so a four hour stream is about 8 GB. That number, rather than the price, is what decides which mobile plan works, because it sets how fast you reach the point where a carrier starts deprioritising your traffic.
