Hollyland COSMO C2 HDMI/SDI Wireless Video 2-Transmitter System (2TX + 1RX)

Tax included Shipping calculated at checkout.

The Hollyland COSMO C2 HDMI/SDI Wireless Video 2-Transmitter System (2TX + 1RX) is a professional, broadcast-grade multi-camera wireless system designed for live video production, directors' monitoring, and cinema sets.

While traditional high-end wireless kits require a separate receiver box for every single camera on set, the COSMO C2 utilizes an advanced 2TX-to-1RX architecture. Powered by Hollyland’s updated HEVO 2.0 transmission technology, this production kit allows a single master receiver to simultaneously capture and display dual-channel video from two independent camera transmitters—saving valuable space on your monitoring rig or production desk.

 

Key Dual-Camera Performance Features

  • Simultaneous Dual-Stream Monitoring: The system handles side-by-side or split-screen rendering on a single monitor setup. The master receiver processes both uncompressed transmitter signals at once, outputting them seamlessly to switcher desks or dual displays via its dual HDMI and SDI output banks.

  • Massive 3,000-Foot Line-of-Sight Footprint: Utilizing an optimized HEVO 2.0 hardware layer, the system punches through heavy environments up to a maximum wireless radius of 3,000 feet (1,000 meters) under clear line-of-sight conditions.

  • Near-Instantaneous 33ms Latency: Video delays are kept down to a mere 33 milliseconds. This ensures that focus pullers, gimbal operators, and live directors can make precision, split-second technical choices without lag.

  • HEVO 2.0 Adaptive Frequency Hopping: Operating on the 5.1 GHz to 5.85 GHz spectrum, the units actively scan for signal clutter. If heavy local Wi-Fi congestion or venue radio interference is detected, the hardware seamlessly changes channels without dropping frames or interrupting your live monitoring feed.

  • Dual-Interface (HDMI + 3G-SDI) Versatility: Each transmitter accommodates both HDMI and pro-grade 3G-SDI inputs alongside a dedicated SDI Loopout port for local on-camera operators. The master receiver mirrors this with dual HDMI and dual 3G-SDI outputs to cleanly feed multi-viewer production monitors or live production switchers.

Hardware Technical Specifications Matrix

System Component COSMO C2 Dual-Transmitter System Specifications
System Bundle Configuration 2 × Wireless Transmitters (TX) | 1 × Dual-Channel Receiver (RX)
Wireless Core Technology HEVO 2.0 Dual-Channel Hopping (5.15 GHz to 5.85 GHz)
Video Resolution Depth Up to 1080p Full HD at 60 frames per second
Transmission Latency Floor Ultra-low 33 milliseconds
Max Line-of-Sight Range Up to 3,000 feet (1,000 meters)
Transmitter I/O Connections 1× HDMI Input | 1× 3G-SDI Input | 1× 3G-SDI Loopout
Receiver I/O Connections 2× HDMI Outputs | 2× 3G-SDI Outputs
Antenna Terminals RP-SMA Threaded Connections (High-Gain Whips included)
Power Architecture Options Integrated Sony NP-F Battery Plates | 2.0mm Locking DC Inputs
Chassis Mechanical Build CNC Aerospace-Grade Aluminum Alloy

What's In The Box?

  • 2 × COSMO C2 Wireless Video Transmitters (TX)

  • 1 × COSMO C2 Dual-Channel Wireless Video Receiver (RX)

  • 6 × High-Gain Omnidirectional Whip Antennas

  • 2 × Mushroom Antennas (for specialized short-range or high-interference scenarios)

  • 1 × 12V / 2A DC Power Supply Adapter (for the master receiver station)

  • 2 × Cold Shoe Mount Adapters

  • 2 × Articulating Magic Arm Mounts

  • 1 × Heavy-Duty Rugged Hard Carrying Case with Custom Foam Cutouts

Power Flexibility on Cinema Rigs: Both the transmitters and the receiver feature a flexible 6V to 16V DC input voltage envelope alongside their native NP-F slots. When rigged onto large cinema cameras or heavy production cages, you can bypass small camcorder batteries entirely by running a D-Tap to locking barrel cable straight from your master V-Mount or Gold-Mount system blocks.
