Reliable Long-Range HDMI-SDI Wireless Video Link

Today I got an inquiry about the reliable long-range HDMI-SDI wireless video link.

I see many of your brilliant products on YouTube; I use audio and video wireless transmitters for YouTube streaming, the most important of which are Holyland and Cine Eye Pro. Their biggest problem is that signals are cut off when they are used in a non line-of-sight environments.

Do you have any devices that fit my needs to overcome these situations?

My requirements are below; lütfen kontrol edin

Transmitter video input source: HDMI veya SDI
Battery Mount: NPF 980 7.4V and DC Supply 12Volt 2amps
Transmitting Area: min500meter to Max 3 km
Camera hothouse mount: Gerekli

Receiver Output Source Video: HDMI veya SDI
Receiver Input Source Audio: 3.5mm Jack required
Video recording facility required, if possible
Battery Mount: NPF 980 7.4V and DC Supply 12Volt 2amps
Camera hothouse Mount: Gerekli

Why Standard Wireless Video Systems Fail in Real Shooting Environments

Many YouTube creators and film professionals rely on wireless video systems such as Hollyland veya CineEye Pro for live production and on-set monitoring.
While these systems work well in open spaces, users quickly discover their biggest weakness in görüş hattı olmayan (NLOS) ortamlar: the signal drops, freezes, or disappears entirely when walls, ağaçlar, or vehicles block the line between the transmitter and receiver.

In real-world productions—street interviews, indoor–outdoor transitions, or drone shots behind buildings—this limitation becomes a serious problem that interrupts workflow and wastes valuable shooting time.

Understanding the Challenge: NLOS Transmission

Traditional 5.8 GHz Wi-Fi transmitters rely on high-frequency signals with limited penetration and poor NLOS performance.
Even a single concrete wall can weaken or completely block the transmission.

Professional users, Yine de, need systems that can provide:

• Long-range stability (500 m to 3 km)
• Reliable operation in NLOS conditions
• Kompakt tasarım with NP-F battery and DC 12V power options
• Professional interfaces beğenmek HDMI and SDI
• İsteğe bağlı 3.5 mm audio and recording functions
• Camera hot-shoe mounting for mobility and convenience

How COFDM Technology Solves the NLOS Problem

The Reliable Long-Range HDMI-SDI Wireless Video Link kullanır COFDM (Kodlanmış Ortogonal Frekans Bölmeli Çoğullama) — a modulation technology proven in military and broadcast systems.

Unlike standard Wi-Fi transmitters, COFDM divides the signal into multiple subcarriers and applies error correction (FEC), etkinleştirme:

• Stronger penetration through walls, ağaçlar, and vehicles
• Higher resilience against multipath interference
• Automatic signal recovery after short obstructions
• Consistent, smooth video even in urban or moving environments

For demanding conditions, sistem destekliyor relay or mesh extensions, allowing flexible deployment across large or obstructed areas.
