Who needs the Wireless TV Transmitter?

Who needs the audio video Wireless TV Transmitter?

The wireless av transmitter mentioned here are for the wireless transmission of video and audio signals from STB/ DVD /IPTV to a TV. There are three main uses for a wireless product:

*If your sources are in a different part of the room than the TV, you can send the signal wirelessly instead of running long cables across the floor (or under the floor, or along the baseboards, etc). This is an especially common problem with projectors.

*If you want to mount your TV on the wall, you need to run power and cables. With wireless, you only need to run power to the TV. The signal from your sources gets sent wirelessly to the small receiver box. In the case of the Pakite wireless tv transmitter, the TV itself can often power this wireless receiver.

*If you want to have your sources and TV in two different rooms. Again, the Pakite wireless tv signal transmitter is a good pick here because it is able to transmit through walls , so you can have a TV in the same room as the sources, and a second TV connected wirelessly to the same sources.

*If you have equipment specifically with HDMI outputs (Blu-ray players, cable boxes, Apple TV and Roku streamers, etc.). This is not for products like Chromecast, or any of the Miracast or WiDi products (which wirelessly stream content from tablets, phones, or laptops). Those are a different category, these are replacements for HDMI cables. HDMI interface devices need a hdmi wireless transmitter to transmit audio and hd video signal.

Keep in mind though, there is a cost to the convenience. Wireless is always going be more temperamental than wired, taking a few moments to sync up (connect) and potentially/occasionally dropping out.

HDMI VS SD Wireless AV Transmitter

HDMI TV and Set Top BOX had appeared on the market, clients may require HDMI wireless transmitter match with HDMI TV. At the same times, their will found he can not or hardly to find the HDMI wireless device supplier.

Here I'd like to state my personal opinion: why most of company would not produce HDMI ? HDMI already appeared on the market, it's correct, but still not the major market, that's the main reason why we would not produce Full HD AV Sender to expand the market.

For technique :  SD Resolution Wireless AV Sender support long range transmission, like PAKITE Brand PAT-260 Transmitter transmission rang is 350 meter. But if you ask for Full HD resolution, the transmission range will be very short(10 M-50 M without any hold back), and the penetrate ability will weak than SD Audio Video Transmitter, then it will be not suitable for used at different room or floor.

For Clients :  Unit price of HDMI video transmitter will be higher than SD Wireless AV Transmitter, SD Wireless AV Sender unit Price approximately $40-$60 if you buy one pcs at local market, the unit price will be much cheaper if you are agents , HDMI Wireless AV Sender EXW Price based on MOQ 100 sets will be $150 -$190,  it's too expensive for ender user, right?

Form Seller: $150 per sets as prime cost make HDMI market become small, it will no profit for the seller. Besides, at the first , buyer will hard to accept the cost .

That's the main reason why HDMI wireless av transmitter is hardly to search. besides, company would like develop wireless HDMI av sender if you has larger market with larger demands.

With wireless being the norm for so many of our electronic devices today, wireless av sender comes with it.

It’s also annoying when you want to put a TV in a room on the other side of the house from where your cable/satellite wiring enters it. I had this situation before I bought wireless av sender. I wanted to put a TV in my living room and bedroom, but there is a cable between set top box and tv. besides, two tv can not connect with one set top box, I am anxious to fixing this problems, but at that time only one option—running the wires along the ceiling and floorboards inside the house or running them over the roof on the outside—was desirable.

Now I found wireless av sender model PAT-260, it support used in different rooms and different floor, wireless transmission make installment step become easier, besides, also you can change channels at tv end, that a surprise, right? normally you have to change channels at set top box end if you know it very well.

You can also use the system to transmit audio and video signals wirelessly from other devices besides your cable box (e.g. DVD players, home theaters, gaming consoles) to your TV. Also, the model is marked SD resolution, but I think it's no difference with HD Wireless AV Sender.

Wireless tv sender use method is very easy, You simply connect the transmitter unit to your digital box and the receiver unit to your TV. Both of them connect using RCA connectors (the ones with the red/white/yellow plugs), which are provided with the units. You then just play with the antennas to align them so the signal moves as directly as possible between the two rooms.

If you have any questions about how to use, please review the video by search key works" PAKITE wireless av sender " at Youtube or Contact Us, we will help you how to install step by step.
