Access control systems let authorized employees get in and out of various parts of your business while keeping other people out. They can range from simple electronic keypads that secure a single door to large networked security systems for multiple buildings that can include parking lot gates, integration with time and attendance systems, and multiple levels of security.

Keypads are common for single door security access and less expensive security systems. They’re easy to use but less secure, since users have a tendency to write down the entry code or to “lend” it to others. They also don't provide detailed audit trails unless you provide each employee with an individual code.

Card readers are the most popular option in commercial access control. They're easy to use, and when cards are lost, it's a simple matter to deactivate them and issue new ones. Proximity cards, which can work from one inch to three feet from a sensor, are the most common. Because there's no contact between the card and reader, they're very reliable and suffer little wear and tear. They're also inexpensive.

You'll also need locks that the security system can control electronically. The two main options for locking standard doors are electric strikes and magnetic locks. Electric strikes are generally cheaper and are better for free exit doors. They're also more appropriate for standard wooden or steel doors. Magnetic locks are better for aluminum and glass storefront doors, as well as for controlled exit situations and emergency exits.
