When you’ve got to shoot a live event, even the shortest, smallest cables can be a major source of annoyance. From tripping and falling to catching on tables, seating and other items, cabling is an irritating necessity of live video that offers just as many downsides as it does advantages.
Add in the fact that cables limit the range of your camera operators and it becomes clear why so many live video companies are looking for alternatives.
Luckily, there’s a great solution out there. Modern wireless video equipment allows you to record live events with ease, all without having to worry about loose cables catching on items or posing a safety risk.
Like all technologies, a wireless video has advantages and disadvantages. It’s convenient, highly portable and surprisingly affordable. However, it does have one downside: many wireless video systems just don’t have the same range as fiber optic video cable.
In this post, we’ll look at the different ranges for hd sdi wireless video equipment and explain what your options are as a video producer. We’ll also share specific recommendations for equipment that’s designed for long range transmission without a noticeable decline in picture quality.
What is the maximum range for wireless video?
There’s no single maximum range for wireless video equipment. Instead, different equipment is designed to allow for a different maximum transmission distance, with our systems ranging from as little as 10 meters all the way up to two miles.
The distance that wireless video can travel depends on several factors. The first of these is the type of antenna that’s used. A small, low-gain antenna is unlikely to be able to transmit video at an acceptable level of quality for a long distance, whereas a high-gain antenna likely can.
Most of the time, you’ll see a direct correlation between price and transmission distance. Some of our low-cost wireless transmitters, such as the VidOlink Reacher Low-Cost Wireless HD-SDI Link, have a maximum range of 3000 feet for HD SDI and HDMI signals.
Add high-gain antennas and this range can increase to 1500 feet, showing the difference that higher quality, more sensitive antennas can make.
Another option is to use a line of sight transmission equipment. This type of equipment has a high transmission distance and little to no latency or interference, largely because it’s designed for a point to point, a line of sight transmission.
As you’d expect, line of sight equipment only provides good performance when there’s nothing in the way of the devices to affect the transfer. Some line of sight video transmission gear, such as the Wireless VidOlink Ranger, has a range of up to two miles.
Lose the line of sight and this equipment will still perform, albeit with a far lower range than the amount you can expect with a direct line of sight between the two devices.
What can affect a wireless video transmission?
A variety of factors can affect the quality of a wireless video. In a live event setting, physical items and objects such as people, plants, and buildings can affect the quality of a wireless signal, with a noticeable decline in the range of a wireless video transmission system.
The best way to avoid this is to make sure there’s always an uninterrupted line of sight between your video transmitter and receiver. Another option is to use wireless ethernet links in areas that contain lots of people, trees, structures and other sources of interference.
Another factor that can affect the quality of your video transmission is the weather. Heavy rain and lightning can negatively affect most video transmission equipment, making it hard to provide a clear signal on rainy or turbulent days.

Over the last decade, the world has gone wireless. From home and office computer networks to VOIP, wireless communications technology has converted a world that was once built for wires into one where both viewers and content creators expect wireless convenience.
While wireless technology is well established on the consumer side of media, it’s less common on the business side. However, new wireless video transmitters and production systems are starting to become popular in a wide variety of industries, for an equally wide range of reasons.
From retail to live events, a variety of businesses in many industries can benefit from adding wireless technology to their toolkit. Below, we’ve listed three industries that can see the biggest benefits from switching from wired to professional wireless video transmitting technology.
Over the last five years, IPTV has become increasingly popular with both large and small retail businesses across the United States. Being able to broadcast content to a variety of devices is an extremely valuable asset for any retail business focused on effective marketing and sales.
Wireless video transmitters make the process even easier. Instead of transmitting video from a source over ethernet or an Internet connection, zero latency wireless video transmitters let you send a video signal from a source to a variety of units without set top boxes or ethernet cables.
This means that in a retail environment, you can broadcast a wireless signal to displays around your store that list new products, special offers and upcoming promotions, all without any wires cluttering up the environment and affecting the customer’s experience.
All that’s required is a wireless video transmitter with a large enough range to cover your retail store, as well as wireless video receivers for each display.
If there’s one industry that can benefit from wireless video transmission, it’s live events. For the most part, live events depend on wired video technology to transmit content from a source — in most cases, one or several cameras — to a variety of displays.
This, of course, has several weaknesses. Cables are a common point of failure in many event environments. Often, all it takes to disrupt a signal and affect a broadcast is excess foot traffic, damaged cables or improper setup in a specific area.
Using wireless video technology, event organizers can simplify the technology side of an event significantly, all while improving results.
During a presentation or keynote speech, video content can be transmitted to displays without annoying cables or bulky equipment. During a live event, camera operators can get in closer to the action without having to worry about potentially hazardous cables.
With many wireless video transmitters capable of sending broadcast-grade video over a range of two miles, even the largest events can benefit from wireless broadcasting technology.
Wireless surveillance cameras, which transmit video over Wi-Fi, have grown in popularity over the last five years. Once uncommon, they’re now a common sight in retail stores interested in improving security, reducing losses and keeping customers safe.
Beyond the convenience factor of wireless surveillance cameras, wireless video has major cost advantages for business. It’s reliable, easy to operate, low maintenance, and typically costs far less than an equivalent fiber optic cable network.
In addition to retailers, a growing number of homeowners are investing in wireless cameras for security purposes. Being able to back up video content and watch video remotely are regarded as some of the biggest selling points of wireless video transmission for home users.

Reliably Transport 4K & HD Video for Synchronous REMI At Home Remote Production – SMPTE Presentation
SMPTE Washington DC Section Meeting – February 2018
The second 2018 monthly meeting of the Washington, D.C., Section took place on 15 February at the National Association of Broadcasters head quarters in downtown Washington. The event held jointly with Chapter 37 of the Society of Broad cast Engineers, featured speaker Jim Jachetta, chief technology officer and executive vice president of VidOvation, describing his company’s work in helping to meet the technological challenges in connection with a fast-paced live reality television show.
An opportunity for socializing and networking preceded the pro gram, which was called to order by Section Chair Tom Hackett. Hackett acknowledged Section members present and introduced Program Committee Chair, Eric Wenocur, who provided information on future Section meetings and other activities.
Jachetta began the presentation by describing his company’s role in assisting with the production of an A&E television series, “Live PD.” He recalled that he was approached by show producers looking for a cost-effective solution for doing the fast-paced live show from as many as seven different cities simultaneously with as many as 36 cameras being deployed in police cars and by on-foot camera operators. Further complicating matters was the requirement for operation of the mobile cameras at speeds as great as 130 miles/hr and maintaining precise synchronism between cameras and accurate lip-synch, as the show runs live without an opportunity to fix slippages in post-production.
The solution proposed and adopted was the use of bonded cellular video/audio transmission technology, utilizing connectivity with multiple service providers to ensure reliability. Jachetta described the specialized antenna units deployed on the various police cars involved in the show, noting that their protective ” radomes” resembled Styrofoam food containers, leading some to joke about the “Chinese carryout” placed on the trunk lids of the police vehicles. An appropriate number of streaming video transceivers were deployed at the A&E master control facility in New York City, where the show was switched. He reported that the project was successful, make the industries first Live Reality Show possible.
Broadcast engineers and operators are always looking for ways to cut the cost of contributing and distributing video between the network and affiliates or between the field and master control. The traditional approach
is to use an expensive telecom connection or satellite circuit, but a far less costly alternative is to send video through the public internet or unmanaged networks, which are practically free. This alternative approach — made possible by AVIWEST’s Patented SafeStreams technology — is already helping major networks save money.
The SafeStreams technology minimizes or eliminates the need for an on-site production truck for remote productions. The transport protocol maintains perfect genlock and lip sync across multiple live IP video connections providing broadcasters with the ability backhaul all cameras back to master control for an “At Home,” or Remote Integration (REMI) production.
The AVIWEST SafeStreams transmission protocol provides reliable, broadcast-quality video transmission over 3G/4G, LAN, Wi-Fi, satellite, and the public internet with advanced forward error correction, dynamic automatic re-requests, IP bonding, and up to 100 percent redundancy.
This session will address the two overarching applications for this technology: 1) contributing/distributing video through the public internet using the AVIWEST HE4000 4K & HD HEVC Encoder, and 2) using the bonded cellular method to backhaul live video from the field synchronously during remote-integration (aka REMI) productions. Attendees will get an overview of the
types of distribution, including point-to-point and point-to-multipoint, and learn how to configure and implement SafeStreams technology correctly in different types of topologies, design a tailored system, and prevent costly mistakes. Attendees will also get a look at the magic of SafeStreams through a real-world example — A&E’s highly popular “Live PD.” The protocol makes it possible to do the unprecedented — home-run video from up to 41 cameras in eight cities back to master control in New York, all in perfect synchronization and lip sync.
