1x2 3G-SDI Splitter for Broadcast Video

The BZBGEAR BG-3GS12 takes a single SDI source and duplicates it to two BNC outputs simultaneously. It handles 3G-SDI bandwidth up to 2.97 Gbps with signal relocking for stable long-distance transmission. Designed for camera operators, live-event crews and AV installers who need reliable distribution without signal degradation. Not suited for buyers who need more than two outputs or HDMI connectivity.

Check Source Resolution and Cable Runs

Verify your source outputs one of the supported formats: SD 480i, 576i or 625i; HD 720p at 24, 25, 30, 50 or 60 Hz; 1080i at 50 or 60 Hz; 1080p at 24, 25, 30, 50 or 60 Hz. Confirm cable type and length match the distance limits: SD up to 200 m, HD up to 120 m, 3G up to 80 m. Ensure the receiving devices accept BNC SDI input and the required colour space such as RGB or YCbCr 4:4:4, 4:2:2 or 4:2:0.

Metal Chassis with Locking BNC Connectors

A rigid metal enclosure measuring 112 by 90 by 29.3 mm and weighing 150 g resists knocks in portable kits. Locking BNC connectors on the single input and dual outputs prevent accidental disconnection during mobile shoots or fixed installs. Passive operation means no external power supply to carry or mount. Compact footprint sits neatly on a camera rig, in a rack shelf or on a desktop without blocking adjacent ports.

Questions about this item

What comes in the box with the BG-3GS12 1x2 3G-SDI splitter?

The unit itself has one SDI BNC male input and two SDI BNC male outputs; any SDI cables or power supply needed for operation are not included and must be sourced separately.

Should I choose this 1x2 model or look for a 1x4 version?

This model splits one SDI source to exactly two outputs; if you need to feed more than two displays or devices simultaneously, a 1x4 or larger distribution amplifier would be required instead.

The headline says 1080p@60 support — what does that mean for my 1080p 60 Hz camera feed?

The splitter passes 1080p at 60 Hz with 3G-SDI bandwidth up to 2.97 Gbps, relocks the signal for runs up to 80 m (262 ft) at 3G rates, and maintains 8, 10 or 12-bit deep color without degradation.
