The first line of security for government agencies is the physical barrier that controls and limits access to the site. These include fences, gates and security cameras. The access control system allows remote monitoring from a central location, ensuring access to all visitors.

The main entrance includes a physical access component of an automatic door opening system such as a sliding door, a revolving door or a sliding door. Depending on the timeframe requirements, an electronic access control system can be added to customize the level of security required. They can also be combined with surveillance cameras and security systems controlled by a central point to record detailed information into the visitor.

To ensure proper day-to-day work, administrative offices such as offices and warehouses must use special products such as master key systems to prevent unauthorized key and logical access solutions from accessing the network or information. From the high-security single-lock lock on the secure warehouse to the padlock on the locker, all products need to be rugged and reliable.

Most rooms are usually open, although they lock when necessary. Rooms such as labs, computer rooms, and secure warehouses may require a higher level of security provided by logical access or identification solutions to access workstations and networks, as well as physical access solutions for open and controlled rooms.

Many students also live in the school dormitory. To ensure a safe and convenient environment, Tri-Circle provides physical access to the dorm, as well as inductive solutions for catering and printing services and access to libraries, laboratories or laundry rooms. Identify solutions such as solutions.

Student IDs such as campus cards based on secure contactless smart cards can be improved to achieve a secure one-card multi-purpose. These include cashless transactions for catering services, vending machines, laundry, and debit card transactions for financial institutions, as well as identification for access to libraries and laboratories.

In emergency situations, emergency exit or emergency exit equipment must be able to evacuate people quickly and efficiently; at other times it must be an important part of the building's main security facilities, by restricting access or ensuring unimpeded security. Strict emergency evacuation and fire safety requirements mean the height requirements for the installation of safety doors and stainless steel doors.
