Wireless Video Transmitters

A video sender (also known as wireless video sender, AV sender or audio-video sender) is a device for transmitting domestic audio and video signals wirelessly from one location to another. It is most commonly used for sending the output of a source device, such as a set top box, DVD player, CCTV camera, DVR, blu-ray player, satellite television decoder, to a television or viewing device in another part of a property and provides an alternative to cable installations. There are two types of interface: RCA or AV and HDMI. HDMI av sender is for transmitting HDMI signal wireless, and there are two types output resolution of a HDMI wireless a/v sender: 576p and 1080p. 576p HDMI av sender is the new wireless av product which launched by PAKITE at 2016. Following is something about wireless video transmitters.

2.4GHz Video Transmitters

2.4GHz Wireless Video Transmitters are an inexpensive solution for sending security camera video wirelessly. There are two types of 2.4GHz video transmitters. The first are analog video transmitters that use RF signals to transmits video and require line of sight with no obstructions between the transmitter and receiver. The 2.4GHz analog video transmitters are great for solutions where Real Time video is required without any lag, or where the signal must be received at multiple receivers. The second type are digital wireless 2.4GHz transmitters that utilize a WiFi like signal modality which allows penetration through obstructions based on their density and strength of the transmitted signal. It is possible to penetrate a solid concrete wall or thin sheet metal wall using a 2.4GHz digital wireless transmitter and a 2.4GHz 16dbi high gain panel antenna.

5.8GHz Video Transmitters

5.8GHz Wireless Video Transmitters allow for long range video transmission without interference from WiFi. At CCTV Camera World we specialize in wireless video transmission, and sell only FCC certified video equipment that conforms to all Federal regulations. The analog 5.8GHz video transmitter can be used along with its 5.8GHz wireless receiver to send video signals. This 5.8GHz wireless video transmitter is great for converting a wired security camera in to wireless because it transmits a Real Time video signal without any frame drops or choppiness. Video quality is almost as good as wired, as long as signal transmission occurs in line of sight and the proper types of antennas are used to maintain good signal strength.

What is HDMI AV Transmitters and Receivers? | PAKITE

Right now, HDMI Connection become the mainstream interface, so Wireless HDMI Transmitter and Receiver comes with HDMI interface. So, What is HDMI wireless av transmitter?

Wireless av transmitter is for transmit AV Signal from signal source（like DVD/DVR/TV Box）to Monitor( TV/display screen), it’s like a wireless bridge between signal source with monitor. HDMI wireless av sender has the same function with wireless av sender, like the upgrade vision of wireless av sender.

It is connection upgrade : for the connection jack, common wireless av transmitter is RCA/AV Jack, but it’s becomes out date in the recent years, HDMI connection becomes common in the new TV/DVD/DVR/TV Box, all of av products support HDMI Input/Output. So RCA wireless av transmitter needed upgrade, we design the new model PAT-580 support HDMI Input/Output.

It is resolution upgrade : for RCA wireless av sender, receiver output resolution is 480P, when the HDMI connection come out, resolution also upgrade. like 480P, 720P, 1080P, 4K. It’s  technical innovation for AV Field.

HDMI Wireless av sender is for cater to market demand, it’s resolution upgrade from 480P to 576P, it’s more slowly than TV resolution, but there is a lot of space for improvement.

How to Read Wireless Audio/Video Transmitter Specifications

Wireless Cable TV Audio/Video Transmission Systems

Wireless audio/video transmission systems consist of two main parts: a Transmitter and a Receiver. The Transmitter uses a wired connection (most commonly via Composite RCA cables or HDMI cables) with the AV output from a source component such as a cable box, satellite receiver, DVD player, Blu-ray Player, Roku, DVR, or Apple TV. The Receiver uses a wired connection with the AV input(s) on a TV. 

 

Once the Transmitter and Receiver are installed the AV signals are sent from a source component out to the Transmitter, wirelessly on to the Receiver and out to the TV. Typical applications for this setup are when the Receiver may be located inside a cabinet, in an entertainment rack, behind closed doors or in another room; and/or the TV is located where a wired connection is not possible or may just simply be an eyesore, like a flat panel wall mount application. Without the need to make long AV wire connections you can place your devices almost anywhere.

CHANGING CHANNELS REMOTELY

A common question with a wireless setup like this is how to change channels if the source component is in another room or in a location without a line of sight to the IR remote. Fortunately most systems include a built-in IR pass-through system. The Receiver features an infrared (IR) receiver, that takes in a signal from your IR remote and passes it wirelessly to the Transmitter and out to an emitter that repeats the IR signal to the source component. If the wireless solution doesn't include an IR pass-through, or if a little more discrete installation is needed.

WIRELESS FREQUENCY

It is also important to understand the frequency that the wireless system uses. Almost every home today is operating on at least one, if not multiple, wireless systems - wireless home automation, phones, doorbells, intercoms, security systems, sensors, speakers and more. Many of these use lower end frequencies, which you will commonly see as a specification of 314 MHz, 433 MHz or 900 MHz. More recently higher end bandwidths have been used, which you will see as a specification of 2.4 GHz or 5.8 GHz. The frequency of the device doesn't necessarily correlate to the quality of the product. The important thing to understand is that you want to try and make sure there aren't multiple products using the same frequency, as this can cause interference and decrease the reliability of the products. Ideally, you will want to be using different frequencies for each set of products to ensure the optimal results of your installation.

EXPANDABILITY

The final consideration on picking the right wireless video transmitter is it's expandability, or the ability to send a wireless signal to more than one receiver. Not all system allow for this, So if you have more than one remote TV that wants to tap into the wireless video signal, just purchase an additional receiver for a system that supports it.
