Access Control Security Becomes Focus on Vendors

In recent years, the security products market in China has experienced steady growth, with access control systems emerging as a key area of development. As the integration of access control and video surveillance becomes more prevalent, the focus on system security has intensified. This article explores various access control security technologies and highlights their importance in modern security applications.

The Rise of IoT Technology

Since the Internet of Things (IoT) was officially included in China’s national development strategy in 2010, it has gained significant momentum. The government has since supported next-generation technologies like IoT and cloud computing, which are now being applied in building automation, security, and smart homes. Many companies have embraced these innovations to enhance their access control solutions. A notable example is the integration of IoT into access control and elevator protection supervision systems, demonstrating how these technologies can improve user safety and system efficiency.

NFC Technology Gains Momentum

As mobile usage increases, NFC technology is becoming widely adopted in areas such as mobile payments, transportation, loyalty programs, and secure information access. Major manufacturers like Samsung, Nokia, and LG are incorporating NFC into their devices, paving the way for its use in mobile access control. Despite its current limitations, NFC holds great potential, especially when integrated with secure platforms that protect identity data and enable seamless access control through mobile devices.

Bluetooth: Secure and Reliable

With growing awareness of security, Bluetooth technology has found its place in access control systems. Though its transmission range is limited, the use of relay devices enhances interoperability and reliability. Bluetooth also offers cost savings in installation and maintenance, making it an attractive option for modern access control setups. Additionally, its low power consumption, ease of use, and strong encryption make it ideal for securing communications between devices.

Encryption Technology Takes Center Stage

Future access control systems will likely rely on homegrown encryption algorithms for enhanced security. Addressing security from three angles—application, device, and algorithm—ensures comprehensive protection. Key management systems play a crucial role in generating and updating cryptographic keys, while secure authentication modules in card readers help prevent unauthorized access. Combining these with biometrics or dynamic passwords can further strengthen security in high-risk environments.

Lessons from Past Security Crises

While the gap between domestic and foreign access control systems continues to narrow, Chinese manufacturers must focus on innovation rather than price competition. By investing in R&D and offering tailored solutions, they can better meet user needs. Meanwhile, foreign brands often lack flexibility and face long development cycles. Domestic companies should leverage their strengths in customization and cost-effectiveness while striving to close the gap in high-end applications.
