Some of the popular control systems include simple to complex card readers, keypads, 24/7 monitoring systems, biometric scanners, and video surveillance. The type of system installed generally relates to the type of business in operation, number of employees, and number of doors to secure.

Here are several key points that need to be evaluated before deciding on the right access control system:

Security
An access control system is there to make sure the building is secure and employees are safe. Any worthwhile system will have basic features like video surveillance, 24/7 monitoring, and card management options. Plus, a high-end system will have the ability to restricted access to certain areas for specific individuals and include biometric scanner options (fingerprint and iris scanners).

The most effective systems rely on a monitoring service that operates over the internet. This makes it easier for the control center to monitor the activities in the office using a standard internet set-up.

Features
A preferred style of access control system will have the ability to provide enough features to match the specific building. Certain systems are designed to only control a limited number of users or access points. Any system installed needs to handle the actual size of the organization.

The method used to authenticate a person entering the premises can vary. Password access is the least secure; access card is slightly more effective, while biometric is the most reliable. The cost of the control system also increases with the level of security, which makes the fingerprint or iris readers the most expensive.

Reports
Many of the advanced systems have the ability to issue reports on the movement or activity of the employees. This makes it very easy to see if an employee attempts to gain access to an area that is unauthorized. Plus, further, reporting can relate to open and close hours, alarm details, and building security. Most of the modern systems will generate reports that are published via email or smartphone for easy access on-the-go.

Outside support
A reliable service is required to provide outside support in the event of concerns or problems arising. Many companies can provide quick support via live chat, telephone, or email. Plus, to learn about the basic operation of the access control system, a variety of resources are provided, including FAQ sections, educational documents, and video tutorials.
