Workplace Access
Management
Our access control systems give you complete authority over who enters your building and when. Staff members receive secure credentials that can be programmed for specific areas and time periods. This prevents unauthorised access to sensitive areas whilst allowing smooth movement for authorised personnel.
The system maintains detailed logs of all entry attempts, providing valuable data for security audits and incident investigations. If theft or security breaches occur, you can quickly identify who was present at specific times and locations.

Residential door entry solutions are particularly popular for apartment buildings and properties with long driveways. Our video entry systems allow residents to see and speak with visitors before granting access. Remote unlocking capabilities mean you can grant access even when away from home.
Commercial door entry systems include multiple authentication methods such as key cards, PIN codes, and biometric scanners. Integration with existing security systems provides comprehensive protection for your premises.
