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.
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.
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.
