Émetteur vidéo numérique longue portée UHF Émetteur vidéo UHF

Unidirectionnel et bidirectionnel sont les deux types d'émetteurs vidéo UHF, which are categorized based on project needs.

Par exemple, an ordinary video photograph camera only needs to transmit the video from the transmitter to the receiver; but drones often not only need wireless transmission from the camera to a remote monitor, and the control instructions issued by the operator at the receiver joystick need to be uploaded to the drone. This is a two-way transmission.

A UHF video transmitter is a device that can send video signals wirelessly over the ultra-high frequency (UHF) groupe, qui va de 300 MHz en 3 GHz. It should include a video transmitter to connect to your camera and a receiver to connect to your monitor. Aussi, support transmitter antenna and receiver to become on a full set of UHF video transmitter systems.

We use UHF video transmitters for broadcasting TV shows and transmitting video from cameras, drones, and other sources.

UHF video transmitters vary in their frequency range, puissance de sortie, schéma de modulation, débit de données, and antenna type..

Perhaps you’ve heard of VHF or very high frequency. It is the frequency range of radio frequency electromagnetic waves (radio waves) depuis 30 à 300 megahertz (MHz). The wavelength range of VHF is from ten meters to one meter.

UHF Video Transmitter – Detailed Overview

Product Definition
UN UHF video transmitter is a device that wirelessly transmits video signals over the Ultra High Frequency (UHF) groupe. It can convert video from sources such as HDMI, IDS, or analog CVBS/AV into radio signals, which are then received by a compatible UHF video receiver.

• Gamme de fréquence: Commonly 300 MHz en 3 GHz, often 500–900 MHz for practical applications.
• Type de signal: Can be either analogique (simpler, low-latency CVBS) ou numérique (compressed, high-quality HDMI/SDI using H.264/H.265 or COFDM modulation).

---

Applications typiques

• Drone/UAV video transmission: Real-time video feedback to ground stations.
• Security and surveillance: Wireless CCTV transmission without long cables.
• Live event broadcasting: Wireless feed for concerts, sportif, or TV production.
• Professional or military monitoring: Low-latency, robust video transmission for reconnaissance or tactical operations.

---

Customer Considerations
When selecting a UHF video transmitter, customers often focus on:

• Video input type: HDMI/SDI (numérique) vs CVBS/AV (analogique)
• Distance de transmission: Varies with power output and environment
• Latence: Critical for drones or real-time control applications
• Signal stability and interference resistance: Digital COFDM modulation offers better robustness in complex environments
• Regulatory compliance: Must adhere to local frequency usage laws
