TEF LINK Security Group Inc. designs, installs and supports professional access control systems for commercial, industrial, institutional and multi-tenant facilities throughout Cambridge, Kitchener, Waterloo, Guelph and surrounding areas.
Whether you need to secure one door or manage access across multiple buildings, we can provide a flexible system that helps protect your property, staff, visitors and critical areas. Access control gives your business better control over who can enter, where they can enter and when they are allowed access. Instead of relying only on mechanical keys, an electronic access control system allows you to assign, remove and manage user permissions using cards, fobs, PIN codes, mobile credentials or integrated security software.
When a key is lost, locks often need to be re-keyed. When an employee leaves, keys may not be returned. With an electronic access control system, credentials can be quickly disabled, schedules can be updated and access events can be reviewed when needed. This gives your business better security, better accountability and a more professional way to manage building access.

Every facility is different. TEF LINK can work with you to design a system that fits your building layout, staff requirements, visitor flow and future growth. Our access control systems can be installed as a standalone solution or integrated with other security systems such as video surveillance, intrusion detection, alarm monitoring and intercom systems.
We provide access control solutions for:
A professionally installed access control system can improve day-to-day building security while also reducing the risk and cost associated with lost keys, unauthorized access and uncontrolled entry points.
Access control can be used on a wide range of doors and controlled entry points. TEF LINK can help determine the right hardware and system design based on the door type, traffic level, fire code requirements, building use and security objective.
Modern access control systems can support a variety of credential types depending on your needs. This may include proximity cards, key fobs, PIN codes, mobile credentials or a combination of methods. For many businesses, cards and fobs remain a practical and reliable option. For organizations looking to modernize, mobile credentials may allow authorized users to access doors using compatible mobile devices.
TEF LINK can help you choose the right credential method based on convenience, security, budget and long-term management requirements.
TEF LINK works with proven commercial access control platforms including Kantech, CDVI and other professional-grade systems. These systems can support small businesses with only a few doors as well as larger facilities that require multiple controllers, user groups, schedules and reporting.

Access control becomes even more powerful when it is integrated with other security systems. TEF LINK can design systems that allow access control, video surveillance, intrusion detection and monitoring to work together as part of a complete security solution.
For example, a door forced open event can be connected with video surveillance so the event can be reviewed. A staff entrance can be controlled by card access while also being monitored by a camera. An intrusion alarm system can be integrated with access control to improve user management and site security.

When planning an access control system, it is important to understand more than just the number of doors. A proper design should consider how the building is used, how staff enter and exit, whether doors are used by the public, whether emergency exits are involved and whether the system needs to integrate with alarms, cameras or intercoms.
