Most wireless video systems are built for one camera and a monitor a few hundred feet away. When the monitors are at the far end of a stadium, the production runs on an NDI network, or a dozen people need to see the picture, you are shopping in a different class. In Hollyland’s line that means two systems: Cosmo C2 and Pyro Ultra.

Both are transmission systems — a transmitter and a receiver that feed monitors you already own. They solve different problems.

At a glance

Cosmo C2: built for networks and multi-camera

The Cosmo C2 is the one to look at if your production already runs over a network. Its transmitter outputs NDI HX3 alongside HDMI and SDI, so the camera goes straight onto the production network with no capture card or converter.

It also works the other way round from most systems: two transmitters can feed one receiver. Add a second Cosmo C2 transmitter ($399) and A-cam and B-cam share one monitoring chain. Latency is 33ms over a 3,000ft link, FPS Booster and fractional frame rates are supported, and the receiver’s customizable frozen frame holds the last good image during a momentary dropout instead of flashing noise in front of a client.

FOR NDI AND MULTI-CAMERA

Cosmo C2 Kit (1TX + 1RX) — $999

3,000ft at 33ms, NDI HX3 + HDMI + SDI, two cameras into one receiver.

Pyro Ultra: built for distance and many viewers

The Pyro Ultra reaches further — 4,900ft, nearly a mile, in standard mode — and carries 4K60 UHD. Its real strength is the other direction from the Cosmo: one transmitter holds a stable link to as many as 20 receivers. The director, the DIT, the client village and the producer can each have their own monitor, and you add receivers ($579 each) as the village grows instead of buying a second system.

DFS certification opens the cleaner 5GHz channels most consumer gear cannot legally use, which matters in venues where every phone is fighting for bandwidth.

Cosmo C2 brings many cameras to one place. Pyro Ultra sends one camera to many places.

FOR LARGE SETS AND LIVE EVENTS

Pyro Ultra Kit (1TX + 1RX) — $1,199

4,900ft range, 4K60 UHD, stable to 20 receivers, DFS 5GHz channels.

Which one should you buy?

• Your switcher or studio runs on NDI: Cosmo C2.
• Two cameras, one monitoring position: Cosmo C2 with a second transmitter.
• You shoot and deliver 4K60: Pyro Ultra.
• Many people need their own monitor: Pyro Ultra plus extra receivers.
• Monitors are very far from camera: Pyro Ultra (4,900ft) over Cosmo C2 (3,000ft).

Hollyland also offers a Cosmo C2 2TX & 1RX kit and a Pyro Ultra 1TX & 2RX kit — ask us if you want either configuration. If your monitors sit within a few hundred feet of camera, both systems are more than you need; start with our wireless video transmission guide instead.
