Components of an Access Control System
An access control platform is fully integrated to manage anything from a small single door to enterprise level management systems, covering access control, elevator control, safety management, automation systems, video management, parking management, situation control, and much more.
- Management Software
- Controllers
- Readers
- Credentials
Credentials
Credentials are cards and tags that can be scanned by a reader.
Access control credentials come in many forms, often as a card, fob, or clicker. These credentials are tied to an individual user and are each encrypted to ensure security. Every single credential in an access control system can be given access rights that only allows them to gain access through certain doors. In essence, credentials allow for the management and monitoring of people through a building.

RF Transmitters and Receivers
Keri’s line of RF Transmitters and Receivers can be used with the PXL-500W family of Tiger Controllers, or any other manufacturers’ access controllers that are 26-bit Wiegand-compatible. One-button and four-button transmitters, typically attached to a key ring, provide up to 500 feet (150 m) of transmit range to the receiver. The four-button transmitter can be programmed for multiple frequencies to accommodate multiple receivers.

Controllers
Our most popular controllers
Take a look at Keri’s renowned access control products, from our NXT MSC range using Mercury Security firmware, to our Bluetooth controlled application.
NXT is Keri’s newest access control platform providing unmatched system flexibility, ease of use, and cost effectiveness. Utilizing true peer to peer Ethernet communications for networking between controllers and software, the system has eliminated the single point of failure prevalent in most other access control systems. A new standard in security, NXT is first of a new generation of equipment to utilize encrypted data from Cards to Readers.
