The Guardian Mockingbird can be programmed in the field using any IR light source or standard white flashlight. This light can copy and transmit any IR or white signature that is put in front of it. With up to twenty seconds of recording time, the possibilities are endless. The Guardian Mockingbird can also clone itself to another IR Guardian or any of our cutting edge VIPIR, Mockingbird, or Quantum products. The Guardian Mockingbird also features our Revers Polarity program Switching. By simply flipping the battery, the user can easily and safely switch between programming and transmission mode.
