Security system

Introduction to Security Systems

Core definition: A system that prevents security threats such as illegal intrusion, theft, and destruction through technical means (hardware + software), and protects the security of personnel, property, and information.

Main types

Physical security systems: Access control (card swiping/facial recognition/fingerprint), surveillance cameras (high definition/night vision), infrared detectors, anti-theft alarm devices;

Network security systems: firewalls, anti-virus software, intrusion detection systems (IDS), data encryption tools;

Comprehensive security system: Integrating physical and network protection, supporting remote monitoring and automatic alarm (linked to mobile phones and property management).

Core functions: Real-time monitoring, abnormal early warning, record traceability (storing monitoring data), risk blocking (such as access control interception, network firewall shielding).

Common application scenarios: homes, enterprise office areas, public places such as shopping malls/hospitals, data centers, and transportation hubs.

Application Scenarios

• Residential homes and smart communities

• Enterprise offices, campuses, and data centers

• Public venues: shopping malls, hospitals, transportation hubs

• Industrial parks and critical infrastructure

Role of Power Devices

Baoquan Zhijie supplies MOSFETs, IGBT MOSFETs, SiC MOSFETs, diode modules, and power modules for security equipment. These devices power surveillance cameras, access-control units, alarm panels, edge-AI gateways, and IoT sensors, enabling high efficiency, low standby power, robust EMI performance, and long-term reliability.
