The CK-GPC04 Series RFID Intelligent Police Equipment Cabinet balances security and operational efficiency through a multi-layered approach:

• 1. Tiered Authentication System:The cabinet employs a three-factor authentication system (biometric, smart card, and password) that can be configured based on equipment sensitivity. High-security items like firearms may require multiple authentication factors, while less critical gear might use single-factor access. This granular control ensures appropriate security levels without unnecessary delays.
• 2. Emergency Access Protocols:For urgent situations, the system includes a dual-factor emergency access procedure using biometric verification plus physical keys. This bypasses normal network dependencies, allowing authorized personnel to retrieve equipment within seconds during critical incidents while maintaining audit trail integrity.
• 3. Pre-Authorization and Rapid Release:The system supports pre-authorization for specific equipment sets tied to particular alert statuses or roles. When activated, pre-authorized users can bypass standard multi-step verification for designated items, enabling swift equipment deployment during emergencies while maintaining strict accountability through predefined protocols.

The cabinet maintains reading accuracy through advanced RF management and compartment design:

3. Sequential Scanning Algorithm:Rather than attempting to read all compartments simultaneously, the system employs a sequential scanning protocol that activates one compartment’s RFID system at a time. This eliminates interference between compartments and ensures each scan captures a clear, unambiguous dataset of the compartment’s contents.

1. Precision Antenna Tuning and Shielding:Each compartment features individually tuned RFID antennas with electromagnetic shielding between adjacent units. This containment prevents signal bleed between compartments, ensuring that scans only register tags within the specific compartment being accessed, achieving ≤3cm cross-read prevention.

2. Dynamic Power Adjustment:The UHF RFID readers automatically adjust transmission power based on real-time tag detection feedback. In compartments with high tag density, the system increases power to ensure all tags are activated, while in sparser configurations it reduces power to optimize efficiency and minimize RF interference.

The system ensures continuous operation through robust standalone functionality and backup systems:

• 1. Local Processing and Storage:The main cabinet includes substantial local processing power and storage capacity (4G+128G configuration) that allows it to operate independently for extended periods. All access control decisions, inventory management, and audit logging continue locally, syncing with central systems once connectivity is restored.
• 2. Redundant Access Mechanisms:In addition to network-dependent authentication methods, the cabinet maintains offline-capable access options including locally stored biometric data and emergency physical key override. This ensures equipment remains accessible even during prolonged network disruptions.
• 3. Battery Backup Power:The system includes uninterruptible power supply capabilities that automatically engage during main power failures. This backup system supports several hours of operation, maintaining critical functions like access control, inventory tracking, and audit logging until main power is restored.
