ESCTL is constantly evolving. Below are the planned improvements and technical requirements for future revisions of the system.

Firmware & Hardware Improvements

• Extended GPIO: Utilizing reserved pins for a second relay and door reed switches.
• Improved Networking: Native support for storing MAC and IP configurations directly in Arduino EEPROM.
• Enhanced Wiegand: Configurable endianness and bit-order for broader reader compatibility.
• PCB Revision 2: Inclusion of reverse protection diodes and voltage dividers for supply voltage monitoring.

Software & Integration

• LDAP Schema Extensions: Extending escToken to include descriptive metadata.
• Admin Interface: Development of a modern web-based administration console for user and token management.
• Mobile Access: Exploring NFC and mobile app-based unlocking mechanisms.
• Granular Permissions: More sophisticated delegation of privileges for managing specific door groups.

Data Standards

• Timezone Standardization: Moving towards consistent local time storage for access intervals, while maintaining GMT for Active Directory synchronization.
• Documentation: Ongoing efforts to document all CAT5 color codes and hardware pinouts for community reference.
