The advantage of having the right professional Boston access control systems contractor on your side is their expertise in everything from basic physical security to advanced electronic security devices. Physical systems, most commonly used for public places, includes preventing unauthorized persons from entering through the use of security guards, bouncers, ticket checkers and so on and physical devices such as turnstiles. This kind of control is a matter of who is allowed to go where and when. This is applied both at entry and exit points. For instance, in a shop, the exit point must be more closely guarded than the entry point, while at a theater it is the opposite.

An important term you will have to be familiar with when you are dealing with a Boston access control systems company is the phrase ‘access control topology’. In these systems, a credential has to be presented to the reader and this has to be accepted by the main controller to ensure access. The means through which the credentials are compared against a pre-programmed list is called the topology of the system. There are many kinds of system topologies, the most common of which is the “serial” type of topology. The communications between the look up and the control functions are connected serially.

If you require a system with networking capabilities too, then a Boston access control systems company can also give you a solution through a system topology that consists of serial controllers with terminal servers. This type of system allows you the advantage of being able to use existing networking infrastructure to connect separate segments of your access control system. This provides one with a good solution where installation of a separate RS-485 cable for a system would be difficult or even impossible. The only problem with such a topology for your system is the increased complexity involved.

Choose a specialist Boston access control systems contractor, and you will have many choices of systems to choose from. These companies have both security experts and access control systems experts on the roll and these professionals will study your needs and conditions and design the perfect system. There are many advanced electronic systems available too, like thumb print readers and other biometric systems. These systems can also be programmed to allow only specifically authorized personnel entry, so you can have specific areas restricted within the same office building!
