Controlled Access is great for any business. It prevents people from gaining access to you building without you allowing them. It also solves the problem of have to replace the lock if you misplace a key. Instead you simply bar the token and deny it access. You can set schedules when you want certain doors to lock and allow and deny access to certain users to certain parts of your building.
At Professional Cabling Solutions we primarily use Paxton because we believe it is the best solution to controlled access and allows easy administration for the end user.
