How can I control my TV without infrared?
Do all remote controls use infrared?
Most remote controls for electronic appliances use a near infrared diode to emit a beam of light that reaches the device. A 940 nm wavelength LED is typical.
What is the difference between IR and RF remote controls?
IR stands for Infared and means the remote must be pointed directly at the receiver. RF stands for Radio Frequency and means the remote is multi-directional. Radio Frequency (RF) operation provides up to 100′ range though walls, floors and doors, indoors or outdoors.
How do I know if my remote is infrared?
Look at the viewfinder or screen of your camera/camcorder or mobile phone. If the remote control sends a signal, you should see a light in the viewfinder or screen of your camera/camcorder or mobile phone when you press a button on the remote control.
Can I download an IR blaster?
Many Android phones come with an embedded infrared “blaster” that uses the same technology as old-school remotes. All you need to do is download a universal remote app like AnyMote Smart IR Remote, IR Universal Remote or Galaxy Universal Remote to use your phone to control any device that receives an IR signal.

How do I find my IR receiver?
How does an IR kit work?
An IR repeater system takes Infrared (IR) light coming from your remote controller and converts it to an electrical signal that can be easily distributed over electrical wiring to one or more IR remote controllable components.
What is IR remote?
Some Android devices have a built-in IR transceiver. This means that they can send and receive IR signals (the same thing used by your typical TV remote control). This makes it possible to control TVs, steros, and other equipment with Unified Remote.
What is IR on a TV?
An infrared blaster (IR sounds better and less techy) is a gadget that accepts some sort of input from your remote and "blasts" it via infrared to the IR-compatible device you're trying to control. A TV's IR blaster allows it to "communicate" with another device, like a cable box.
Why infrared is used in remote control?
An IR remote (also called a transmitter) uses light to carry signals from the remote to the device it controls. It emits pulses of invisible infrared light that correspond to specific binary codes. These codes represent commands, such as power on, volume up, or channel down.
What is MWIR and LWIR?
The three wavelengths are: Short Wavelength Infrared (SWIR), Medium Wavelength Infrared (MWIR), and Long Wavelength Infrared (LWIR). All Thermal imaging devices operating on the infrared wavelength are, 'imagers' that we commonly refer to as 'cameras', however they are actually sensors that can detect radiated heat.
Does IR work through walls?
Since infrared is a light wave, the signal is limited in distance and cannot be sent through walls or other solid objects. This is called line-of-sight. However, heat sources and sunlight can interfere with the light waves.
