Frequently asked questions
How far can I go with 12G-SDI?
The distance depends on the cable type. Belden’s distance chart is on our Video cables page; describe your application and we will choose the cable together.
Can I use 4×3G-SDI (quad-link) instead of 12G-SDI?
Yes; some devices carry 4K over four 3G-SDI links. Single-link 12G-SDI reduces the number and weight of cables. DTA-2174B supports both.
How do I stream 4K over IP?
BLANKOM SHDE-4000 turns a 12G-SDI source directly into an IP stream (SRT, HLS, RTMP, UDP).

- If you know the model: the model, quantity and delivery country are enough.
- If you are planning a project: describe the sources, distances and target format; we choose the encoder, card, cable and connector together.
