Wireless Camera Broadcast



Have you ever wondered how a wireless camera broadcast works?

If that's a yes, then we'll give you an insight into its mode of operation as well as some wireless broadcast camera transmitters. 

If you're searching for the best wireless HD video transmitters in 2018 that will allow you to stream high-resolution TV shows, and sports, at seamless frame-rates, then this may come in handy.

But before we proceed, here's what to expect in this post:

  • What is a Wireless Camera Broadcast?
  • What is a Wireless Broadcast Transmitter?
  • How does Wireless HDMI Transmitters Work?
  • Benefits of Wireless Transmission
  • Best Wireless HDMI Transmitters
  • How Were These Wireless Broadcast Transmitters Selected?


What is A Wireless Camera Broadcast?


A Wireless camera broadcast is mostly used in Television production to transmit information between the transmitter and receiver.

This broadcast can either be from a digital or analog camera, where the former does not require physical connections with cables before transmitting.

If you're wondering why,

It is because a digital wireless camera takes advantage of reflected signals on a concrete wall or window for transmission and has error correcting algorithms and modulation settings that help to enhance image quality.


What is a Wireless Broadcast Transmitter?


A wireless broadcast Transmitter is usually packaged as a kit also containing a Receiver.

You can connect the Transmitter to a Video camera, Satellite, Computer, Gaming console, DVR / Set-top boxes, DVD players, Blu ray player, and other HDMI-enabled devices wirelessly.

HDMI cables can be used for this connection due to their high-speed network connectivity, but physical connections with the use of wires are required.

And you know the score:

This would mean having to deal with obtrusive cables through your hallways and a connection that may need to be done by a professional.

On the other hand, 

HDMI wireless transmitters which have become popular, do not require a line-of-sight connection and they can provide faster network speeds for streaming 4k videos.

See the difference?

Let's proceed!


How do Wireless Transmitters Work?


On connecting a Transmitter to your source device, you can attach a Receiver to your television or projector whose job is to receive high-def signals from the Transmitter.

The result from your wireless HDMI transmitter & receiver system?

You'll be able to stream high-definition Spongebob Squarepants, Shrek and other movies from any room and also transmit HD videos through walls or ceilings to another room.

You would've also eliminated any potential messy or constraining cables.

Now,

These transmitters have different features, protocols, and limitations due to their data transmission technology, thus their method of operation may vary.

As an example: 

The Wireless Home Digital Interface (WHDI) Transmitter with a frequency of 5 GHz can have a high latency where packets of audio and video that are to be sent are delayed due to interference in the airwaves. 


This limitation is removed by employing Dynamic Frequency Selection to minimize static or distortion by automatically selecting a low interference frequency channel.

In line with that,

Protocols such as the Wireless HD and WiGig featuring a 60 GHz wavelength can have a slower speed when the line of sight between the transmitter and receiver is blocked by an object.

Here, their speed of connection can be maximized by removing the object that is directly in their path.


Benefits of Wireless Transmission

Some benefits of connecting wirelessly instead of using HDMI cables include the following:

1. Long-range connections:


You can connect to sources that are not in the same room with your TV or projector and from a long distance without any interference. In the past, this would've only been possible by running cables


2. Multiple Connections:


It allows you to connect a source to more than one device at a time.

For instance, you can have a TV connected to a source such as a computer and a TV in another room connected to the same source.


3. Unrestricted TV location:


If you choose to mount your TV on the wall, then it can be done neatly since the only cable that will be lying around will be the power cable.

HDMI cables are not needed due to the wireless connection that allows signals to be received from a source.

Now that's out of the way,

Let’s get busy with some professional wireless video transmitters for streaming the highest resolutions of videos from a device with an HDMI port.

How These Wireless HD Video Transmitters Selected?


Several factors have to be put into consideration before finally settling for a Wireless HDMI Transmitter.

While they're all important depending on your purpose for acquiring it, some are more important.

Therefore the following factors were given utmost priority in our selection process.

  • Latency
  • Range of operation
  • Video and Audio Quality
  • Data Transmission Technology


1. Latency: 


A transmitter with a latency period that is over 1 millisecond may encounter video buffering and occasional delays while trying to send audio and video data.

For this reason, our selected Transmitters either have no latency or one that is less than that 1ms which will ensure that it processes information quickly.


2. The range of operation:


The distance between the transmitter and the receiver before the signal is lost or the audio/video quality is affected is determined by the range that is coverable between both devices.

Thus, you'll find Transmitters with at least 100ft in our guide which can send signals through standard walls, ceiling, and floors in a bid to ensure that you can stream seamlessly from a wide area or different area from your source device.


3. Video and Audio Quality:


A device with a 1080p resolution promises the best image quality, hence each of our chosen HDMI Transmitters features the same either for 3D or 4k.

Moreover, there also offer support for 1080i, 720p and other video formats to enable you to make a choice between a higher and lower resolution.

In terms of audio capabilities, you'll find between 5.1 to 7.1 digital audio support that ensures what you hear is as clear as possible.


4. Data Transmission Technology: 


A WHDI Transmitter using a technology such as Dynamic Frequency Selection is always recommended since it will always opt for the ideal channel to minimize buzzing, static, or distortion.

In that case, you'll find a Transmitter such as the Nyrius Aries Pro featuring such.

On the other hand, we also opted for Wireless HD transmitters with high transmission frequency to prevent any interference that may be caused by air or thick objects.


Conclusion:


Using our wireless HDMI transmitter review as a guide in selecting your next HD video transmitter, a cable can be a long forgotten option in no time.

Also,

You can expect the best video and audio quality with each of these devices given their high-end technological specs.

It’s now in your pitch to test one of these wireless hdmi transmitter and receiver kit which will enhance your entertainment at home or in the office.
