WHEN TO USE RF VERSUS IR CONTROL SIGNALS

Hospitals, Large Clinics-Use IR to avoid interference from other radiating devices nearby
ENT Offices-Use RF for easy installation and omnidirectional control
Multiple Sound Rooms-Use IR to avoid cross interference between booths or a combination of (RF) and (IR) to cover multiple rooms
(RF offers up to 4 different channels of operation)

RF Description & Pros/Cons

RADIO FREQUENCY (RF) is a wireless transmission of control signals on a specific radio frequency (433MHz) radiating outward in all directions equally through most materials. Bit coding ensures secure transmission and reduces false positive responses. Approximately 15 meters range.

PROS OF RF

• omnidirectional radiation
• easy installation (one less cable to run)

CONS OF RF

• possible interference from other RF devices
• limited number of operating channels

IR Description & Pros/Cons

INFRA-RED (IR) is a wireless transmission of a control signal using infra-red spectrum light waves to flood the room. IR light cannot pass through solid/opaque objects containing the signals within the space it is used. Approximately 5 meters range.

PROS OF IR

• no possible interference
• the signal is contained within the room

CONS OF IR

• will not go through walls or solid barriers
• must position IR sensors close to remote control emitter
• cannot use multiple IR systems in same room.
