Professional 4-Channel HDMI/SDI Video Switcher with Built-in H.264/H.265 Encoder and RTMP/RTSP Live Streaming
Procurement managers in the broadcast, event production, and education sectors frequently face challenges securing reliable multi-input video switchers at competitive unit prices with short lead times. This all-in-one professional video switcher integrates 1× SDI and 3× HDMI inputs, real-time encoding, and live streaming capabilities to deliver seamless 1080p@60Hz switching and distribution without compromising on performance or supply chain efficiency.
Key Features and Business Benefits
4-Camera Switching with PGM/PVW Dual Outputs: Supports seamless transitions and fade-in/fade-out effects for professional multi-camera live production. This enables reliable program and preview monitoring, reducing on-site errors and post-production time for conferences, events, and courseware recording.
1× SDI Input with 100m Lossless Transmission: Accepts broadcast-level SDI signals at up to 1920×1080/60Hz with support for up to 100 meters using RG6 75Ω cable. It provides robust signal integrity for longer cable runs common in venue installations, eliminating the need for additional converters or repeaters.
3× HDMI Inputs and 2× HDMI Outputs: All channels support 1080p@60Hz with HDCP 1.4 compliance. This facilitates straightforward integration with consumer and prosumer cameras, laptops, and displays, streamlining system setup for mixed environments.
Built-in Hardware Video Encoder: Features H.264/H.265 encoding with RTMP/RTSP protocols over Gigabit Ethernet (RJ45). Maximum bitrate reaches 8Mbps at 1920×1080@50Hz push/pull streaming, enabling direct live broadcasting to platforms without external encoders and lowering overall system costs.
Advanced Audio Processing: Supports HD embedded audio, external analog audio (MIC/LINE IN), and flexible mixing with LINE OUT and HD audio following PGM output. Audio formats include PCM and AAC (48KHz), ensuring synchronized, high-quality sound for professional productions.
OSD Information Display: Shows input channel, resolution, volume, and encoder IP address (default: 192.168.1.55) on output. This supports real-time monitoring and quick troubleshooting during live operations.
Additional Operational Advantages: Power-off memory for settings retention, high-quality keys with color backlight, and compact design (180×135×52 mm, 557g) for easy integration into racks or portable setups. Operating temperature range of -15℃ to +55℃ ensures reliability across diverse environments.

Frequently Asked Questions
Q: What is the maximum reliable cable length for the SDI input?
A: The SDI input supports up to 100 meters of lossless transmission using RG6 75Ω HD digital video cable at 1080p@60Hz, suitable for large venue installations without additional signal extenders.
Q: Does the unit support direct live streaming to platforms like YouTube or Facebook?
A: Yes. The built-in encoder supports RTMP/RTSP protocols over the RJ45 Ethernet port, allowing direct push streaming at up to 8Mbps without external hardware.
Q: How does the audio mixing function work across inputs?
A: The switcher accepts HD embedded audio or external analog MIC/LINE IN, performs mixing, and outputs via LINE OUT or embedded in the HD PGM signal. Audio can follow PGM output or be independently routed.
Q: Is HDCP compliance supported, and what resolutions are handled?
A: All HDMI interfaces comply with HDCP 1.4 and support 1080p@60Hz input/output. SDI input also handles up to 1080p@60Hz with broadcast-level signal conversion.
Q: How is reliability ensured for continuous operation in live events?
A: The unit features power-off memory for settings, a wide operating temperature range (-15℃ to +55℃), and hardware-level encoding stability validated through factory testing protocols.
