Forms of remote-control

Remote control can be separated in two categories: wired or wireless.

Remote control is different from remote communication in a way that the second device usually does not change the logic and that each signal usually represents an action rather than information.

(In consumer electronics, a remote control is the device to control a TV or set-top box. Also an RC-car is an (often radio) controlled miniature vehicle.)

Wired

A wired remote control system isn't all that different from a regular system. The increased length of wiring might bring in problems though. For long-distance wiring, interference and signal strength might become a real problem. The use of differential signals (RS-422, RS-485) in combination with quality (shielded) twisted pair cables should extend the maximum possible cable length. The use of internet might also be an solid option for wiring remote control systems, but you should be very wary of security risks (and even then, it's still a risk). High-risk applications are "never" connected to the internet.

Wireless

For setting up a wireless connection, there are several protocols/implementations around.

Such as: Bluetooth (HC-05/06), WiFi (Esp2866), Light/IR, radio signals or magnetics (limited range).

The security of wireless can also be a risk, since the signal could be intercepted/altered.

Directional

Some remote control applications are bi-directional, which means that there is no defined "master" or "slave" device. And that both the devices can control each other.
