Which of the following is NOT typically part of technical support in access control systems?

Custom hardware solutions typically fall outside the scope of technical support in access control systems. Technical support is more focused on assisting users with existing systems and resolving any issues they may encounter. This includes troubleshooting system failures, offering software updates and maintenance, and providing user training sessions to ensure that users can effectively operate the system.

Designing custom hardware solutions requires specialized knowledge and resources that go beyond what is usually offered by support staff. Such tasks are typically undertaken by engineers or developers who create the systems rather than those who maintain or support them once they are operational. Therefore, choosing to include hardware design as a function of technical support is misaligned with the common practices in the field.
