امروز یک پرس و جو در مورد پیوند ویدیویی بی سیم برد بلند HDMI-SDI دریافت کردم.
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?

Why Standard Wireless Video Systems Fail in Real Shooting Environments
Many YouTube creators and film professionals rely on wireless video systems such as Hollyland یا CineEye Pro for live production and on-set monitoring.
While these systems work well in open spaces, users quickly discover their biggest weakness in غیر خط دید (NLOS) محیط ها: the signal drops, freezes, or disappears entirely when walls, درختان, 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, با این حال, need systems that can provide:
- Long-range stability (500 m to 3 کیلومتر)
- Reliable operation in NLOS conditions
- طراحی فشرده with NP-F battery and DC 12V power options
- Professional interfaces مانند HDMI and SDI
- اختیاری 3.5 mm audio and recording functions
- Camera hot-shoe mounting for mobility and convenience
Introducing the Reliable Long-Range HDMI-SDI Wireless Video Link
To solve these real-world challenges, we developed the پیوند ویدیویی بی سیم HDMI-SDI برد بلند قابل اعتماد, الف COFDM-based H.265 transmitter and receiver system designed for stable, low-latency video transmission in both LOS and NLOS environments.
This solution is ideal for فیلمسازان, YouTubers, UAV operators, and live broadcasters who require a robust wireless connection up to 3 کیلومتر without dropouts or interference.
ویژگی های کلیدی
- Stable Long-Range Transmission:
Achieve up to 3 کیلومتر خط دید یا 500 m in NLOS conditions using advanced COFDM modulation and diversity reception. - Professional HDMI/SDI Interfaces:
Both transmitter and receiver support HDMI and SDI input/output, ensuring full compatibility with cinema cameras and monitors. - تأخیر بسیار کم:
Powered by فشرده سازی H.265, system latency can be as low as 30–150 ms, perfect for live streaming or synchronized monitoring. - منبع تغذیه انعطاف پذیر:
پشتیبانی می کند NP-F980 battery mount و DC 12V/2A input, making it adaptable for both field and studio use. - Audio & Recording Support:
Receiver includes a 3.5 mm audio jack and optional SD-card recording, allowing backup or direct capture of transmitted video. - Camera-Mount Ready Design:
Lightweight aluminum enclosure with hot-shoe mount, ideal for on-camera use during shooting or live broadcasting.
How COFDM Technology Solves the NLOS Problem
این پیوند ویدیویی بی سیم HDMI-SDI برد بلند قابل اعتماد uses COFDM (مولتی پلکسینگ تقسیم فرکانس متعامد کد شده) — 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), را قادر می سازد:
- Stronger penetration through walls, درختان, 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, سیستم پشتیبانی می کند relay or mesh extensions, allowing flexible deployment across large or obstructed areas.
برنامه های کاربردی
- Professional YouTube and live streaming production
- Film and TV on-set monitoring
- UAV or drone video transmission
- Vehicle-to-ground or ship-to-shore communication
- Outdoor event coverage and ENG (گردآوری اخبار الکترونیک)
Real-World Example
A professional content creator needed a reliable 500 m–3 km wireless setup for outdoor YouTube interviews across city streets.
After switching to the پیوند ویدیویی بی سیم HDMI-SDI برد بلند قابل اعتماد, they achieved a stable HD feed with zero dropouts and minimal delay — even when the camera was behind buildings or moving vehicles.
The result: seamless live workflow and professional-quality broadcast under challenging NLOS conditions.
If your current wireless transmitter suffers from instability or short range, it’s time to upgrade to a پیوند ویدیویی بی سیم HDMI-SDI برد بلند قابل اعتماد.
Combining تکنولوژی COFDM با H.265 ultra-low-latency encoding, this system delivers unmatched ثبات, محدوده, و قابلیت اطمینان for both LOS and NLOS environments.
Whether you’re shooting a live YouTube show, a film project, or a drone mission, this wireless link ensures your video stays connected — anywhere.
