In some places, the electronic interference of wireless and cordless devices jams out door and gate transmitters.
TrioCode™ overcomes this challenge by simultaneously transmitting on three different frequencies, so even if two are jammed, TrioCode™ will still work.
Also, TrioCode™ transmitters use a random coding system with 4.29 billion possibilities for enhanced security. Available in both keyring and wireless wall mount models.
