- This is the ultimate IR emitter, built with the professional integrator in mind and providing simplified, smooth installations and high reliability. The low-profile vIRsa is unobtrusive and adjusts to any installation environment with a flexible film adhesive that conforms to curved surfaces. For fast troubleshooting, a separate holder remains attached, allowing easy removal and replacement of the emitter. A blue LED flasher offers increased visibility but may be hidden during normal operation. In addition, a translucent PCB improves the integrity of electrical connections while a built-in resistor protects against over-driving.
