🔐 Physical Security Technologies
1. Smart Locks
Smart locks are electromechanical devices that allow doors to be locked and unlocked using electronic methods such as keypads, biometric sensors, access cards, Bluetooth, or Wi-Fi. They often integrate with mobile apps for remote access and monitoring. Some models include features like facial recognition and integration with smart doorbells for enhanced security. en.wikipedia.org
2. Biometric Access Control
Biometric systems use unique biological traits—such as fingerprints, facial features, or retina patterns—to verify identities. These systems are increasingly used in secure facilities and devices to ensure that only authorized individuals gain access. investopedia.com
3. Tamper-Evident and Tamper-Resistant Devices
Tamper-evident technologies provide clear indications if a device or package has been interfered with, using methods like security seals or shrink bands. Tamper-resistant designs make unauthorized access more difficult, often incorporating special materials or construction techniques. en.wikipedia.orgen.wikipedia.org

🌐 Network and Data Security
1. Firewalls and Unified Threat Management (UTM)
Firewalls act as barriers between trusted and untrusted networks, filtering incoming and outgoing traffic. UTM devices consolidate multiple security functions, including antivirus, intrusion detection, and content filtering, into a single platform. mobilestalk.net
2. Multi-Factor Authentication (MFA)
MFA enhances security by requiring multiple forms of verification, such as a password (something you know), a smartphone (something you have), and a fingerprint (something you are). umatechnology.org
3. Hardware Security Modules (HSMs)
HSMs are physical devices that manage digital keys and perform cryptographic operations. They are essential for securing sensitive data and are commonly used in industries requiring high levels of data protection. en.wikipedia.org

🎥 Surveillance and Monitoring Accessories
