Core Features & Functionality
- Dual-Channel Control: You can wire channel one to a garage door operator and channel two to an automated entry gate, or control two separate garage doors from a single receiver box.
- High Security Access: Because it operates on the proprietary MegaCode format, it eliminates the risk of code duplication or signal interception from standard code-grabbers.
