Technical Resources
This section provides technical guides and implementation best practices for access control and vehicle identification systems. Topics include Wiegand and OSDP communication protocols, serial interfaces, credential formats, and integration considerations for RFID and LPR deployments. These resources are designed to support system designers, integrators, and technical teams with practical, field-oriented guidance for both new installations and system upgrades.
Protocols & Standards
Educational guides covering access control communication protocols, credential structures, and interface standards used in RFID and LPR system integration.
Comprehensive overview of Wiegand signaling, D0 and D1 wiring, cable length limitations, grounding practices, surge protection, and installation best practices for reliable reader-to-controller communication.
Detailed explanation of 26-bit and 37-bit Wiegand credential structures, parity allocation, facility codes, and format matching considerations for system compatibility.
Technical guide to Open Supervised Device Protocol, including RS-485 architecture, Secure Channel encryption, bidirectional communication, and migration from legacy reader wiring.
Side-by-side comparison of Wiegand and OSDP communication standards, covering security, wiring architecture, device supervision, and migration considerations for modern access control systems.
Practical guidance on serial communication standards used in access control, RFID integration, and vehicle identification systems.
Vehicle Identification Technologies
Educational guides explaining the technologies used to automatically identify vehicles in access control, parking, and transportation environments. Topics include RFID-based identification, automatic vehicle identification (AVI) systems, and license plate recognition (LPR).
Overview of radio frequency identification technology and how RFID readers and vehicle-mounted tags communicate to enable secure, hands-free vehicle identification in access control and transportation systems.
Introduction to automatic vehicle identification systems and how technologies such as RFID and license plate recognition are used to identify vehicles automatically in parking, gated access, and transportation applications.
Explanation of license plate recognition technology and how intelligent cameras capture and process vehicle plate numbers to enable automated vehicle access control and monitoring.
