A vault door is a specialized type of security door and an indispensable component of bank vaults; its performance in theft prevention, fire resistance, and structural integrity directly impacts the overall security of the vault. Vault doors come in a wide variety of designs, including standard steel-panel vault doors, emergency vault doors, stainless-steel vault doors, and double-leaf stainless-steel vault doors, among others. The economical and practical standard steel vault door is widely used in small vaults at grassroots financial institutions; its affordable price and high functionality have earned it widespread favor among users. As societal conditions continue to evolve, the protection level of this type of vault door has also been significantly enhanced, with the highest protection rating now reaching the national Class C standard. The multi-functional, luxury stainless-steel vault door is manufactured using the most advanced international technologies and production processes. It is currently the most premium model available in the domestic market, integrating multiple protective features—including water resistance, fire resistance, anti-pry protection, resistance to flame-cutting, and blast-proof capabilities—while being equipped with U.S.-imported (UL-certified) mechanical combination locks and high-end computerized fingerprint locks, thereby achieving the highest national protection rating (Class C). The double-leaf stainless-steel vault door is the preferred choice for bank issuance vaults, offering generous dimensions and cost-effective materials. The mortise locks are installed at the top and bottom of the door, and the joint between the two leaves adopts a tongue-and-groove design. Access is controlled by either a computerized fingerprint lock or a mechanical combination lock, with the main operating knob serving as a versatile control handle; the protection level is Class C.

Characteristics

1. Strong anti-theft performance. 2. High security rating of the door lock, typically featuring dual locks and high-complexity multi-password locks. 3. Sturdy design and heavy construction. 4. Excellent fire-resistant and vandal-proof performance.

Advantages of Bank Vault Access Control Systems 　　

1. A rigorous door-access procedure ensures that every individual entering the vault complies with the bank’s management regulations. 2. A unique “N+1” management model: “N” refers to on-site verification by N individuals (who may be assigned to different departments or hold different positions), while “1” denotes remote on-duty personnel in monitoring centers located at separate sites. The “N” and “1” components mutually check and balance each other; neither can be omitted. 3. The “N” and “1” configurations can be adjusted according to varying network conditions. When the network is functioning smoothly, “1” consists of on-duty staff at the local branch or sub-branch monitoring center; when the network is disrupted, “1” comprises senior managers such as the branch manager or sub-branch director. 4. The “N” and “1” can also be configured based on different time periods—for example, during business hours, “1” is the on-duty staff at the branch or sub-branch monitoring center, whereas after hours, “1” is the on-duty staff at the central branch monitoring center. 5. Intuitive, real-time monitoring of door-status information, including applicant details and live photos, as well as real-time tracking of door-opening/closing status and lock-status changes. 6. The door-opening button on the interface lights up only when front-end verification meets the access criteria and the door-opening window is within the authorized time frame, thereby ensuring mutual checks between front-end operations and back-end management. 7. The system hardware is designed to industrial-grade standards, with all wiring ports equipped with overcurrent, overvoltage, lightning-protection, reverse-polarity protection, and miswiring prevention features. Even if accessories such as power supplies or electric locks fail and output excessive voltage, the motherboard will remain protected. 8. The system software incorporates a dual watchdog design, virtually eliminating the risk of system crashes and ensuring stable operation at all times. 9. The system is used in conjunction with a hardware encryption dongle and includes an automatic interface-lock feature (automatically locking after 30 seconds of inactivity), thereby strengthening back-end security and leaving no room for malicious actors to exploit vulnerabilities. 10. A strict shift-handover protocol with automatic alerts for unauthorized departures or absences. 11. Flexible report-generation capabilities, including real-time queries for door-access logs (access time, accessing personnel—comprising the “N+1” team—and access method—direct opening or software-assisted opening—as well as the identity-authentication methods for both the “N” and the “1”), and real-time queries for shift-handover records (querying all shift-handover records for a specified door or for a designated operator).

Applications in the Financial Industry

The financial industry has been a pioneer in the practical application of security surveillance technologies; its evolution in security has essentially mirrored the transformation of the entire security sector, and its emerging trends often serve as a barometer for the industry’s direction. Currently, criminal activity targeting banks in China is on the rise, with methods becoming increasingly diverse, violent, and sophisticated. High-profile cases such as copycat theft, armed robbery, unauthorized misappropriation, and financial fraud are occurring with alarming frequency, directly threatening the safety of people’s lives and property as well as the stability of the broader socio-economic order. Existing bank security systems primarily focus on video capture and storage, with relatively isolated subsystems that offer very limited information sharing. Integration, intelligent automation, and centralized management remain underdeveloped, resulting in largely reactive monitoring. These systems are mainly used to provide evidence for post-event investigations, but they fall short of effectively preventing or deterring serious violent incidents against banks—such as the Wuhan CCB bombing and the massive bank shooting in Nanjing. Moreover, because branch offices and sub-branches cannot share surveillance footage, when an incident occurs at a particular location, higher-level authorities are unable to obtain a timely and comprehensive overview of the situation. At the same time, various high-tech crimes pose a significant threat to banks’ financial operations. A visualized security management platform is the core component of modern bank security systems. Under this platform, security is no longer merely a passive safeguarding function; it has become an integral part of the bank’s digital management infrastructure. The platform is designed to support all aspects of the bank’s security management, integrating multiple subsystems—including branch video surveillance, anti-theft and anti-robbery alarms, access control, GPS tracking of cash-in-transit vehicles, fire protection, intercom systems, GIS mapping, lightning protection, intelligent analytics, and asset lifecycle management—into a cohesive, unified whole. Each subsystem can seamlessly exchange information and be flexibly invoked, enabling not only traditional security monitoring but also business process management, equipment asset management, and firearms storage management through video feeds, access-control card data, and workflow forms. This creates a comprehensive, efficient, and intelligent integrated security management platform that delivers security services to every business unit within the bank.
