Seajei is a real-time video and audio streaming SaaS and SDK for smart home and IoT devices, targeting use cases such as smart doorbells, baby monitors, security cameras, and companion mobile apps. Its core pitch is to bring the audio/video experience of IoT devices closer to real-time communication apps like FaceTime, WhatsApp Video, and Zoom, with a focus on slow connections, stuttering on poor networks, and high audio/video latency.
Based on the available materials, Seajei emphasizes reliable transmission even under very poor network conditions: bandwidth as low as 0.2 Mbps, packet loss of up to 60%, connection and first frame/audio playback in under 1 second, and two-way audio/video latency of around 0.2 seconds. For security, it provides per-session end-to-end encryption, while using cloud technology to support scalability and availability. The SDK can be embedded into existing apps and device firmware, and the company claims it can be made to work with only a small amount of code.
On the developer support side, the SDK includes sample applications, developer guides, an API Reference, and libraries. It currently explicitly supports iOS and Linux, with Linux coverage for Raspberry Pi, multiple ARM variants, MIPS, PowerPC, and x86-64; Android is still under development. The API documentation lists components such as CjConnectivity, CjVideoPlayer, CjVideoCapture, CjAudioPlayer, and CjAudioCapture, suggesting it is more of a low-level streaming capability integration toolkit than a general-purpose application development platform.
Pricing is $0.0012 per device per minute, with a free trial available and discounts negotiable at larger scale. For customers that need more control, Seajei offers technology licensing with access to the full source code, and allows cloud components to be run and managed in the customer’s own cloud. This is especially valuable for hardware vendors and teams that care about data control or cloud cost optimization.
Its strengths are a clear positioning and deep focus on real-time audio/video for IoT under poor network conditions; concrete performance metrics; and the availability of SaaS, SDK, source-code licensing, and technical consulting. The drawbacks are that public information lacks details on SLA, compliance certifications, customer case studies, and payment methods; Android is not yet available; ecosystem integrations appear limited; and China access plus local support are not disclosed. It is best suited to smart hardware teams with embedded devices that need to quickly improve their audio/video experience, especially products such as doorbells, cameras, and monitoring/care devices.
The website does not provide information on availability in mainland China, node coverage, payment methods, or ICP filing, so China accessibility should be considered unknown. For large-scale commercial use targeting domestic Chinese users, network connectivity, latency, compliance, and payment support should be carefully validated. Comparable alternatives include Agora, Twilio, AWS Kinesis Video Streams, self-hosted WebRTC solutions, as well as China-based options such as Tencent Cloud Real-Time Communication, Shengwang, and ZEGO.
