Basic Features

Features
Modules
Feature Description
Video Capture
Field Device SDK
Capture camera video via RTSP, V4L2 protocols, supports formats like mjpeg, yuyv, and h264.
Video Input
Field Device SDK
External input video image or compressed video data can be used as the transmitted video stream.
Video Session
Field and Remote Device SDK
Field device transmits video to remote equipment, supporting up to 8 simultaneous video paths per single on-site equipment.
Audio Session
Field and Remote Device SDK
Send and receive audio data, used for audio calls between field and remote equipment.
Control Transmission
Field and Remote Device SDK
Send and receive binary data, can be used for real-time interaction and sensor data control between field devices and remote devices, providing different QoS levels transmission guarantee.
Video Link Monitoring
Field and Remote Device SDK
Real-time monitoring of video link network latency, packet loss rate, frame rate, transmission bit rate, etc.
Latency Monitoring
Field and Remote Device SDK
Real-time monitoring of video transmission delay, control transmission delay, and video control closed-loop delay.
Video rendering
Remote Device SDK
Render and display video images in the specified window, providing various rendering configurations such as image, scalability method, etc.
Session Management
Field Device SDK
Automatically manage the audio and video stream transmission status based on control requirements to avoid invalid stream transmission, save bandwidth, and automatically handle network disconnection exception recovery issues.
Control Right Management
Field and Remote Device SDK
Set the control rights for field devices, providing explicit management for control right switching to avoid control risks caused by misoperations.
Audio/video storage
Field and Remote Device SDK
Local storage for control session audio/video files.
Audio/video push
Remote Device SDK
supports RTMP bypass push, which can be used for live streaming or cloud storage.

Features
Modules
Feature Description
High Compression Encoding
Field Device SDK
Supports AV1 high compression ratio encoding:
NVIDIA Orion Platform 1080P video can be compressed to 1 Mbps.
Built-in Tencent Self-developed Encoder (X86 Platform) 1080P video can be compressed to 500 Kbps.
Dynamic Encoding
Field Device SDK
Based on the real-time network status, the frame rate, resolution, and encoding method of the encoding can be flexibly changed to save network bandwidth, improve network packet loss resistance capability, and can be used in scenarios with extremely weak network coverage.
Error correction encoding
Field Device SDK
Supports variable-length error correction encoding, allowing flexible adjustment of encoding redundancy. The SDK provides two modes: adaptive change of error correction encoding redundancy based on real-time network status and specified redundancy.
Text overlay
Field Device SDK
Each frame can have custom text overlay for annotation or watermark, supporting Chinese and English fonts.
Local stitching
Field Device SDK
Supports local stream mixing of multiple video streams with customizable mixing layout.
Multi-network transmission
Field Device SDK
Supports session transmission using multiple network paths to improve transmission reliability in weak outdoor network environments, such as scenarios where a single ISP network cannot guarantee coverage. It supports control flow and video stream transmission in different modes, allowing specific multi-network transmission strategies for different weak network scenarios.
Night vision enhancement
Remote Device SDK
Supports enhanced processing of nighttime video, with adjustable enhancement levels. Processing delay <2ms.
Super resolution
Remote Device SDK
Supports automatic super resolution processing for low resolution screens to match display resolution with a processing delay <2ms. In case of 2x scaling, PSNR is about 32dB compared to the original image.
