Quick Answer
Choosing the right access control system depends on three things: how many doors you need to control, how many users will have access, and whether you need to integrate with other systems (alarms, CCTV). For most small to medium businesses in Northern Ireland with fewer than 20 doors: start with Smart Air. For larger premises or multi-site operations: go straight to Incedo. Always get a site survey before deciding — door types, existing hardware, and building layout all affect the right choice.
