Live broadcasts with wireless technology


The use of wireless technology offers us greater mobility and flexibility in live broadcasts. In addition, we minimize the visual impact at any event since a multitude of cables are not used for different connections.


The cameras emit the signal via cable, normally with an SDI connector. During the assembly of the event, the best route is drawn so that the cable that must reach the location of the camera does not hinder the passage of people, or remains visually discreet. Cable glands are usually used if they cannot be flown, or alternative routes can be traced. Hollyland's Cosmo video signal transmitters allow us to emit the video signal wirelessly, and through a receiver we receive the signal in the production rack.

Avoiding cables is a great advance, but the mobility that working wirelessly offers us is even better. In the past, a steadycam needed an assistant who had to prevent the operator from tripping over the cables. Today a steadycam camera has freedom of movement, wirelessly transmitting the signal from any place in the range of action, which makes it easier to be present where the action of the event requires image support from steadycam.

The Altair WBP 200HD wireless intercoms allow fluid communication between camera operators and the filmmaker, with an ever-increasing range, without interference, and with long-lasting battery life.


The ability to adapt in a live broadcast is key to guaranteeing an optimal result. There are thousands of examples where it is necessary to change the dynamics and cover actions with the freedom that wireless technology offers. Fixed cameras visually cover much of the action, but their number is usually limited and there are endless micro actions that we need to cover. The wireless camera operator is absolutely mobile and autonomous, with the flexibility to send a signal from anywhere, including offering shots designed to provide aesthetic beauty to the production, with movement, or fixed from unique angles.

In many projects we use a dolly for the camera. This is on wheels without the need for tracks, which allows the camera to be moved to different places to offer different perspectives. Thanks to wireless broadcasting we obtain great flexibility working with dolly, gaining speed and offering us a wide range of possibilities so that the broadcast is dynamic and professional.

Special mention to 4G/5G backpacks, a transmission solution that allows you to take advantage of the capacity available in mobile telephone networks. This technology only needs to have coverage to work and be able to send both video and sound, exponentially expanding the radius of action. In addition, its battery also allows us a long autonomy.
