How much does it cost to develop a Real-Time Audio/Video Streaming Device with Embedded Control?
Project Context & System Requirements
WizzDev was responsible for developing the embedded software layer of a Real-Time Audio/Video Streaming Device, integrating with the client’s proprietary hardware and optionally connecting to cloud infrastructure (e.g., AWS). The mobile app and parts of the cloud backend were delivered by external teams.
During the Proof of Concept phase, we implemented core firmware features such as secure pairing, emergency stop functionality, control of system components, and cloud-based action logging. Real-time audio and video streaming was also supported to ensure compatibility with the mobile app.
In the MVP phase, the firmware scope expanded to include remote program control, parent account registration, and real-time handling of motion, sound, lighting, and camera modules.
Current Key Pain Points Identified
To address these challenges, WizzDev delivered a modular and robust firmware solution, optimized for real-time responsiveness and tailored to the needs of a Real-Time Audio/Video Streaming Device. Close collaboration with the client and third-party teams ensured smooth integration across mobile, cloud, and hardware layers.

Solution Overview
The solution architecture used modular firmware blocks to interface with diverse hardware peripherals and meet real-time processing demands. Actions like motion activation, audio playback, and lighting adjustments triggered immediate cloud logging for traceability and analytics.
A key element was the design of low-latency streaming pipelines to synchronize audio and video feeds—critical for any Real-Time Audio/Video Streaming Device requiring smooth, real-time communication. The firmware also enabled fine-grained control via mobile interfaces, including motor speed, brightness, and playback settings—exposed through structured APIs and message handlers.
All modules were optimized for low resource usage and high responsiveness, ensuring seamless system interaction and a smooth end-user experience.
