4 Channel 4K SRT RTMP RTSP UDP 4in1 3G 6G SDI Video Capture Box Card Encoder Transmitter Live Broadcast IPTV

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • 4K Video Capture & Encoding: Supports simultaneous capture of 4K resolution via 3G/6G-SDI inputs, with H.264/H.265 encoding for high-quality streaming and recording.
  • Multi-Protocol Compatibility: Enables live broadcast transmission via SRT, RTMP, RTSP, and UDP protocols, ensuring seamless integration with platforms like IPTV, streaming services, and surveillance systems.
  • Multi-Channel Flexibility: Equipped with 4 BNC ports for SDI inputs, allowing concurrent processing of multiple video streams for complex setups.

Key features

  • 1. Corrosion-Resistant Aluminum Enclosure

    • With a durable aluminum body, ensure reliable operation in demanding environments while improving heat dissipation. This metal construction offers superior durability compared to plastic-based encoders*, making it ideal for professional settings.

  • 2. Multi-Protocol Flexibility

    • With support for SRT, RTMP, RTSP, and UDP protocols, adapt to diverse streaming platforms and network conditions. This 4-in-1 protocol compatibility simplifies integration with existing systems compared to single-protocol devices*.

  • 3. 4K Ultra-HD Encoding Efficiency

    • With H.265 (HEVC) and H.264 codecs, achieve 4K resolution streaming with up to 30% lower bandwidth usage than H.264-only encoders*. This ensures high-quality broadcasts without sacrificing transmission speed.

  • 4. Multi-Channel Live Streaming Capacity

    • With 4-channel 3G/6G SDI inputs, handle simultaneous multi-camera setups for live events or surveillance systems. This doubles the input capacity of 2-channel encoders*, enabling scalable professional workflows.

  • 5. Global Compliance Certifications

    • With certifications like FCC, RoHS, and EPR (France/Germany), meet stringent international regulatory standards for eco-friendliness and safety. This ensures seamless deployment in Europe and beyond compared to non-certified alternatives*.
