Whether you’re a seasoned professional or a videography novice, you’ve likely heard about wireless video transmission. You might even have wondered what is it. So let’s see something that you need to know about it.
Definition
In signal wireless transmission system, transmitter and receiver perform their own functions. To be specific, one transmitter accepts a wired video signal (usually HDMI and/or SDI), converts it to wireless signal which is either uncompressed or compressed, and transmits the wireless signal out over a wireless frequency through antennas. Meanwhile, the receiver accepts the wireless signal from the transmitter, and converts it back to uncompressed video which is transmitted over wired connections (usually HDMI and/or SDI).
Six benefits of wireless transmission system
After having a brief understanding, you can also learn about its benefits and see whether it is suitable for you. The followings are main advantages.
Easy Setup
Compared to traditional wired transmission system, wireless video transmitter and receiver kit is obviously convenient and easy to set up because it only takes you several seconds to pair and connect them by buttons. You don’t have to run long wires and look for correct interfaces to build connection between the video source and the video display.
Flexibility
No cables design enhances flexibility for these devices. Video crew could move the wireless video transmitter around and take videos within distance the system supports, even through the crowd. Oppositely, cables limit distances as well as possibilities sometimes.
Cost Savings
A system of wireless video transmission may be good at saving your money because you don’t have to buy extra devices such as USB disks and converters. Besides, the rapid development and high demand of wireless transmission bring a massive supply of wireless video transmitters and make their cost affordable.
Versatility
A kit of professional wireless video transmitter and receiver can be widely used for many occasions. At the workplace, you could use it to output video presentation from the PC to a conference room TV. At outdoors, you could take a vlog or street interview and transmit the image to the receiver. At home, it can function as a wireless video security system where you can monitor inside and outside.
No Interference
Featuring with dynamic frequency selection, the wireless video transmitter is able to automatically search for frequency channel with low interference, send and receive video in the best channel. You will have no worries about noise interference in your video.
Safety
Getting rid of wires, wireless video transmitter and receiver minimize risk of tripping people down during video shooting. Moreover, tested and certified transmitters and receivers ensure proper working temperature even long-time outdoor recording.
How to choose good wireless video transmission device?
Three basic aspects following deserve to be considered in terms of choosing wireless video transmission devices.
1. Decide connected equipment
First of all, it is necessary to figure out what video equipment you use as input source and output destination. Some kits have SDI or HDMI inputs outputs or both. You could choose one video transmission system with corresponding interfaces with your devices.
2. Consider transmission distance
Wireless video system has its own transmission distance which can be affected by actual shooting distance and obstructions. Thus, you may need to know the needed transmission distance of your video and how many obstacles may exist between the transmitter and receiver beforehand. The range of video transmission can be divided into line of sight and non line of sight. For one wireless video transmission system, it supports to transmit longer distance in line of sight than non line of sight because obstructions will shorten the transmission distance significantly. So have a whole analysis of the shooting environment before you get a wireless transmission device. For example, if you are going to send HDMI video to backstage or spectator seats, a mid-long-range HDMI transmission system could be an ideal partner.
3. Set acceptable delay time
The latency in wireless transmission of video may affect your work a lot. It is better to learn about how much latency the transmission system produce and predict how much effects it could make to your video. If the picture and audio are not in sync or other sync problems come up, the quality of video would be decreased a lot. The lower latency you desire, the higher-quality system you may need.
When and what to use: product recommended
All these beneficial features make wireless video transmission suitable for more demanding shooting environments. When filming concert, talk show, song and dance parade, sport events, documentary, etc., video crew have more options to position the camera and more possibility to find an optimal even in a tricky location, such as at the middle of auditorium, on the high terrace or in the marching crowd. Wireless transmission system allows production staff to monitor the camera footage through camcorder or other external devices freely at a distance, without cables limit.
More and more video producers are devoted to creating videos of various themes in different situations, and also multi-angle shooting can enrich their videos. If you have similar needs and are looking for a more comprehensive and professional system, you might want to take a look at MOMAN Matrix 600S wireless video transmission system.
The Matrix 600S from MOMAN uses fanless design to arrive an ultra-low level of power consumption. Compared to other traditional wireless systems with fans, using Matrix 600S to shoot can reduce recording noises and ensure clearest audio, which makes your post-production work highly-efficient.
Meanwhile, the low power consumption brings longer battery life and makes it support to be powered by USB type-C or NP-F batteries. With Matrix 600S transmission system, you could shoot longer and richer video and have portable charging options at outdoors.
Long distance and HD transmission are considered as significant factors to a wireless video system. Impressively, the Matrix 600 Algorithm system could work within 600 feet in line of sight with receiver and in 0.08s latency, offering more freedom in choosing sites of shooting and monitoring. Built with HDMI and SDI inputs and outputs, it supports up to 1080p 60Hz video format and delivers uncompressed HD wireless video transmission, which you can use various professional devices to shoot and transmit high definition videos.
Conclusion
With the help of wireless video transmission, you have more shooting and monitoring options and get much more flexibility and freedom for shots that you really want. No matter what you are working on or planning to present, just enjoy shooting!
