Frequently Asked Questions
What’s the difference between Wiegand and OSDP protocols in access control?
These are two key protocols for communication between readers and controllers. While Wiegand is a legacy standard limited to 500 feet communication distances, OSDP is a newer protocol offering extended ranges up to 4,000 feet and enhanced security features. Modern controllers often support both to enable gradual system migration.
How do different controller architectures affect system capabilities?
Controller architecture — whether single-door IP products, traditional panel designs or distributed intelligence — impacts scalability, maintenance and cost. Single-door controllers simplify installation but may cost more in large deployments, while traditional panel architecture can be more cost-effective for enterprise implementations requiring multiple doors per controller.
What factors should organizations consider when selecting controllers?
Key considerations include the number of doors to control, desired communication protocols, existing infrastructure, future expansion plans and compliance requirements. Organizations should also evaluate controller features like offline operation capabilities, database capacity and integration requirements with other security systems.
How does controller selection impact total system cost?
While controller hardware costs are important, the total cost calculation should include installation requirements, infrastructure compatibility, maintenance needs and future upgrade paths. Controllers that leverage existing wiring and support system growth can provide significant long-term savings despite higher initial costs.
