Rolling codes standard in advanced garage door remote controls

Garage door remote control suppliers are improving security features and operation to achieve better control. RFID technology, anti-jamming and auto-release functions are adopted.

TOP TRENDS

• Rolling codes: More midrange and high-end models employ rolling codes to enhance security. Units work with ASK modulation on 315 or 433MHz. Most makers accept custom specifications for the operating frequency, and fixed or rolling code encryption.
  
• Automatic operation: Suppliers employ traditional RF or the latest RFID technology. The first requires in-vehicle installation and uses the car horn as actuator. RFID models, which are more expensive, enable a more seamless connection between the receiver mounted in the garage and the card or tag.
  
• Mechanical & circuit enhancements: Anti-jamming, -bump and auto-release functions are added to mainstream devices. Makers are also using programmable time delay in closing the door. Built-in lamp and an emergency stop button are optional. Some high-end varieties support soft start and stop.
  
• Price projections: Several companies expect prices to be the same or increase slightly in the next six to 12 months.
