Real-Time Video Streaming
What we do
Low-latency video is one of the least forgiving things you can build. Codecs, NAT traversal, relay infrastructure and mobile hardware acceleration all have to work together — and the tolerance for lag is measured in milliseconds. We have been building it since well before it was a checkbox feature.
Problems we solve
Typical reasons clients come to us for this work:
- Off-the-shelf video services add too much latency or cost too much at scale.
- Video needs embedding directly in your product rather than handing users to a third-party tool.
- Streaming works in testing but collapses under real concurrency.
- Mobile video drains batteries or overheats because it is not using hardware acceleration.
- Devices in the field need to deliver video to an app efficiently.
Who it’s for
- Platforms embedding live video between staff and customers.
- Hardware manufacturers adding camera or doorbell-style video features.
- Products needing conferencing-grade quality without building a media team.
- Companies whose video costs scale worryingly with usage.
Technologies & capabilities
Protocols
WebRTC in JavaScript and native, H.264 and AAC-ELD, peer-to-peer networking.
Performance
Hardware-accelerated encode and decode on iOS and Android for conferencing-grade latency.
Infrastructure
ICE and relay servers on Node.js and EC2, AWS auto-scaling for thousands of concurrent sessions.
Data
AWS Kinesis and Athena for logging and analytics, DynamoDB for signalling state.
Analytics
On-the-fly video analysis with TensorFlow.js where the product calls for it.
How we deliver
1. Understand
We start with the hard part — the constraint the project actually turns on. Latency, power budget, data volume, regulatory limits. That is what shapes the architecture.
2. Prove
Where there is genuine technical risk, we prove it early with a focused prototype rather than discovering it late in the build.
3. Build
Iterative delivery with working software you can see. Test-driven where it earns its place, continuous integration throughout.
4. Harden
Scale, failure modes and cost. We design for intermittent connections, awkward data and real concurrency rather than the happy path.
5. Support
Handover that leaves you able to run it — infrastructure as code, documentation and, where wanted, ongoing help.

Frequently asked questions
How low can the latency go?
We have delivered conferencing at a quality comparable to FaceTime across iOS and Android, using hardware-accelerated H.264 and peer-to-peer connections with relay fallback. In practice the target is sub-second and the architecture is built around protecting that.
Can it scale to large numbers of concurrent users?
Yes. We have architected AWS auto-scaling infrastructure supporting thousands of concurrent calls, including the ICE and relay server layer that most teams underestimate.
Do we need native apps, or can this be browser-based?
Both are options and often both are needed. We build WebRTC in the browser and native implementations in Swift and Kotlin, sharing the same signalling and infrastructure.
Can you add video to our existing hardware product?
Yes. We have designed and optimised the AWS delivery architecture for doorbell-style video on connected security hardware, working alongside the client’s embedded team on the device side.
