Device Security
Device security is implemented at hardware and firmware levels to ensure only trusted software is executed, protecting systems from tampering and unauthorized modifications.
Secure Boot
Ensures only trusted firmware is executed during system startup.
Firmware Integrity
Digitally signed firmware prevents unauthorized modification or tampering.
Access Control
Role-based access control restricts device configuration and operation permissions.
Network Security
Network security ensures all data transmitted between devices and systems is protected through encryption and hardened communication protocols.
Encrypted Communication
Supports HTTPS and TLS encryption to protect data transmission.
Secure Protocol Stack
Hardened IP communication protocols reduce attack surfaces across networks.
Network Access Control
IP filtering and authentication mechanisms ensure controlled device access.
Data Protection
Data protection ensures that all sensitive information generated by surveillance systems is securely stored, transmitted, and managed.
Data Encryption
Protects data during transmission and system communication.
Secure Storage
Prevents unauthorized access to stored system data.
Privacy Protection
User-related data is isolated and handled according to privacy principles.
