Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing protection schemes are implemented to protect security equipment from EMP/IEMI, then equipment reliability improves, but system cost increases significantly
Solution Approach 1:
The system divides protection into two segments: critical components (storage media, computing equipment) are placed in electromagnetically-shielded cabinets, while non-critical components (cameras, detectors) remain outside. This selective segmentation provides necessary protection while avoiding the prohibitive cost of shielding the entire system.
Solution Approach 2:
The shielded cabinet and storage media are prepared in advance to preserve data during EMP/IEMI events. By having the protective infrastructure ready beforehand, the system can maintain reliability without requiring expensive real-time protection mechanisms for all components.
2Object-affected harmful factors
If comprehensive electromagnetic shielding is applied to all security equipment, then protection against EMI/EMP improves, but device complexity increases
Solution Approach 1:
The system segments equipment into shielded and unshielded zones based on criticality. Only the cabinet containing storage media and computing equipment is electromagnetically shielded, while cameras and detectors operate outside the shielded zone, reducing overall system complexity.
Solution Approach 2:
The electromagnetically-shielded cabinet acts as an intermediary barrier that protects critical components from EMI/EMP without requiring modification or shielding of the external cameras and detectors. This intermediate protective structure simplifies the overall system architecture.
3Reliability
If real-time data protection during EMP/IEMI events is implemented, then data preservation improves, but system response time decreases due to additional processing
Solution Approach 1:
The system continuously stores video and detector data in the shielded cabinet's storage media in advance of any EMP/IEMI event. This preliminary data preservation eliminates the need for real-time protection processing during an event, maintaining both data integrity and system response time.
Solution Approach 2:
The shielded cabinet autonomously preserves data during EMP/IEMI events without requiring active intervention or additional processing. The continuous storage operation and electromagnetic shielding work automatically, preventing data loss without impacting system response time.

AI summary
The present invention relates systems and methods of electromagnetic protection for integrated video and electromagnetic detector security system equipment. A security system configured to be protected from electromagnetic events or attacks includes a quantity of video cameras and a quantity of electromagnetic event detectors disposed at a facility. The system also includes an electromagnetically-shielded cabinet containing computing equipment and a storage media. The electromagnetically-shielded cabinet is configured to receive data from each of the quantity of video cameras and electromagnetic detectors and store the data on the storage media, whereby, in the event of an electromagnetic event, information at the time of the event can be preserved on the storage media. Additionally, the electromagnetic detectors can trigger the video cameras to scan the surrounding area once an electromagnetic event has been detected such that images of suspicious vehicles, persons, packages or other items can be recorded for future forensic investigations.
