A service call this week involving an IR system reminded us of the potential issues these systems can present. IR systems, commonly used to control older or remotely located devices like cable boxes or DVD players, consist of a transmitter (often called the “eye”) and receivers.
The "eye" is typically placed in the room where the remote is used, requiring a clear line of sight between the remote and the transmitter. The receiver, connected to the eye via a wire, must be positioned near the IR sensor (or “eye”) of the device you want to control. When the remote sends a signal, the eye captures it and transmits it through the wire to the receiver. The receiver then “blasts” the signal to the target device, simulating a direct remote-control interaction.
Common problems arise when the transmitter’s line of sight is blocked, or the receiver has been moved. Either scenario interrupts the signal flow, preventing the remote from turning the device on. If your IR-controlled devices fail to respond, double-check your IR system's setup before troubleshooting the components themselves.
