SDI Splitter 1 to 4 Outputs - Long Range SD, HD, 3G Distribution

Our review of this SDI splitter finds it best suited for video professionals and installers who need reliable, low-latency distribution from a single SDI camera or source to multiple monitors or recorders. The unit's biggest selling point is its built-in repeater and wide voltage range, which together make it easy to place near cameras or hubs and drive clean SD, HD and 3G-SDI signals over long cable runs. For anyone needing straightforward, durable 1-in 4-out SDI distribution with plug-and-play setup, this is a strong, practical choice.

Key Features

• Multi-rate SDI support: Accepts SD-SDI, HD-SDI and 3G-SDI so the same unit handles legacy and modern camera feeds without configuration.
• 1 input to 4 outputs: Distributes one source to four simultaneous SDI destinations for monitoring, recording, or routing to switchers.
• Repeater and equalization: Built-in equalizer and reclocker extend reliable transmission and recover signal integrity over long Belden 1694A runs.
• Long cable reach: Supports up to 1320 ft for SD, 660 ft for HD, and 330 ft for 3G signals using appropriate coax, reducing the need for extra signal boosters.
• Wide voltage range: Accepts DC 5V to 30V which makes it flexible for field power options and project installations.
• Durable build and support: Metal enclosure with plug-and-play operation and a one-year warranty plus lifetime technical support.

Who It's For

The splitter is aimed at video technicians, small broadcast setups, and post houses that need a compact, reliable way to feed multiple devices from a single SDI source. It is especially useful where runs of coax are long and a repeater function is required to preserve picture quality at the far end.

It is less suitable for users who need matrix switching or signal conversion to HDMI without extra gear, or those who require more than four simultaneous outputs. For complex routing or built-in format conversion, a dedicated router or converter would be a better fit.

Pros & Cons

Pros

• Supports SD, HD and 3G-SDI so one box covers common professional formats.
• Repeater function with equalization improves signal quality over long cable runs.
• Wide DC 5V~30V input makes field power configurations simple and flexible.
• Sturdy metal enclosure and generally positive user reports on build quality and continuous operation.

Cons

• Does not include format conversion to HDMI, so additional adapters are needed for HDMI-only monitors.
• Picture quality received mixed mentions from some users, which can depend on cable quality and connected equipment.
