Anti-pass back capacity prediction for access control systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control systems face challenges in predicting and managing anti-pass back capacity, leading to operational and performance issues when the number of APB enabled access controllers exceeds the host system's processing capabilities, potentially impacting timely access and overall system efficiency.
Innovation Solution
An anti-pass back capacity predictive system and method that identifies and compares the number of APB status messages generated to a baseline threshold, determining the type of APB feature used and the number of APB enabled controllers, readers, and valid card transactions to assess the host system's capability and optimize APB feature deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of APB enabled access controllers is increased to improve security coverage, then the security capability is improved, but the host system processing capacity is exceeded leading to performance degradation
Solution Approach 1:
The system performs preliminary capacity prediction by calculating the number of APB status messages that will be generated based on the proposed configuration of APB enabled controllers, readers, and card transactions. This allows stakeholders to determine beforehand whether the host system can support the planned APB deployment, preventing performance degradation before it occurs.
2Reliability
If the APB feature is enabled across multiple controllers to prevent unauthorized access, then the security against tailgating is improved, but the number of APB status messages exceeds the host system threshold causing operational issues
Solution Approach 1:
The system calculates and compares the projected number of APB status messages against the host system's baseline threshold before deploying the APB feature. This preliminary assessment ensures that APB is only enabled in configurations that will not cause message processing delays or exceed system capacity, maintaining both security and timely access.
3Reliability
If more APB enabled readers and controllers are deployed to enhance security monitoring, then the anti-pass back capability is improved, but the host system becomes overwhelmed with status messages reducing overall system efficiency
Solution Approach 1:
The system performs a comprehensive capacity prediction calculation that considers the number of APB enabled controllers, readers, and estimated card transactions. By comparing this predicted message volume against the host system's processing capacity threshold, the system determines the optimal configuration that maintains anti-pass back capability without overwhelming the host system, thus preserving overall efficiency.

AI summary
An anti-pass back capacity predictive system and method for an access control host processing system are provided. Some methods can include a host system identifying a number of APB status messages generated by the host system in connection with the host system monitoring a facility, the host system comparing the number of APB status messages generated by the host system with a baseline threshold value, when the number of APB status messages generated by the host system is less than or equal to the baseline threshold value, the host system determining that enabling an APB feature in the facility will be successful, and when the number of APB status messages generated by the host system is greater than the baseline threshold value, the host system determining that enabling the APB feature in the facility will fail.
