they're lights emitted by devices like LEDs to send data and signals that we can't see with the human eye.

Infrared technology is what most TV remotes use. The distance an infrared signal can travel varies based on the strength of the remote, but is usually less than 50 feet for household electronics. In order for an infrared signal to be detected, there must be a direct line of sight between the transmitter (remote) and the receiver (TV). If there is a wall or large object between them, the signal will not pass through it.

i learnt this in physics the other day.
infrared is basically a wave [part of the electromagnetic spectrum] and anything hot gives off infrared
an example of infrared technology is: police night cameras have infrared in them so they can show heat being given off
Normal shuttle cameras use infrared to detect heat/waves from the surroundings.
so infrared technology is technology that uses infrared signals/waves/whatever you wish to call it.

infrared (IR) is light of a particular frequency, the presence of which cannot be detected by human eye from a specified distance...
IR is is mainly used for night vision observation and night photography... IR photography is widely used for detecting underground water, petroleum, and mineral deposits under the earth surface with the help of cameras mounted on satellites...
IR light is also used for physiotherapy for treating joint and muscle pain in hospitals...
