802.1X - Network Admission Control

IEEE 802.1X is an IEEE standard for port-based Network Admission Control. It provides authentication to devices attached to a network port (wired or wireless), establishing a point-to-point connection, or, if authentication fails, preventing access on that port. 802.1X is based on EAP (Extensible Authentication Protocol).

In a 802.1X enabled network switch, clients equipped with the correct software can be authenticated and allowed or denied network access at the Ethernet level.

Clients and servers in an 802.1X network may need to authenticate each other by some means. This is done with the help of digital certificates provided by a Certification Authority. These are then validated by a third-party entity, such as a RADIUS server, examples of which are Free Radius and Microsoft Internet Authentication Service.

To perform the authentication, the RADIUS server uses various EAP methods/protocols, of which there are many. The one used in the Axis implementation is EAP-TLS (EAP-Transport Layer Security).

The AXIS network video device presents its certificate to the network switch, which in turn forwards this to the RADIUS server. The RADIUS server validates or rejects the certificate and responds to the switch, and sends its own certificate to the client for validation. The switch then allows or denies network access accordingly, on a preconfigured port.

The authentication process

RADIUS

RADIUS (Remote Authentication Dial In User Service) is an AAA (Authentication, Authorization and Accounting) protocol for applications such as network access or IP mobility. It is intended to work in both local and roaming situations.

CA servers

In cryptography, a Certification Authority (CA) is an entity that provides signed digital certificates for use by other parties, and thus acts a trusted third party.

There are many commercial CAs that charge for their services. Institutions and governments may have their own CA, and there are free CAs available.

231D+, 232d+ specifications

Axis Communications, a leading provider of IP security solutions, offers a range of high-performance cameras designed for various surveillance applications. Among their products, the Axis 232D+ and Axis 231D+ stand out for their robust features and advanced technologies, making them suitable for both indoor and outdoor environments.

The Axis 232D+ is a high-speed dome camera that delivers exceptional video quality, thanks to its 1/4-inch progressive scan CCD sensor. It offers a resolution of 704x480 pixels and can capture incredibly detailed images at up to 30 frames per second. With its pan/tilt functionality, the 232D+ can cover a wide field of view, allowing for extensive monitoring areas while maintaining high precision and responsiveness.

In addition to its impressive image quality, the Axis 232D+ features advanced digital zoom capabilities, enabling users to zoom into specific areas without significant loss of detail. The camera is equipped with a powerful infrared capability, allowing it to capture images in low-light conditions effectively. This makes it an ideal choice for 24/7 surveillance in all lighting scenarios.

On the other hand, the Axis 231D+ offers similar high-quality video performance but introduces some distinctive features. It also utilizes a 1/4-inch progressive scan CCD sensor and supports a wide dynamic range (WDR) for improved image quality in challenging lighting conditions. The 231D+ is designed for easy installation and integration into existing systems, making it a versatile option for various surveillance needs.

Both models leverage Axis' digital PTZ technology, providing users with the flexibility to pan, tilt, and zoom remotely via an intuitive web interface. This user-friendly aspect simplifies monitoring and allows quicker responses to incidents when they arise.

Furthermore, both the Axis 232D+ and 231D+ support Power over Ethernet (PoE), eliminating the need for separate power cables and simplifying installation, especially in hard-to-reach locations.

In conclusion, the Axis 232D+ and 231D+ represent Axis Communications’ commitment to delivering high-quality, versatile surveillance solutions that meet the demands of modern security challenges. Their advanced imaging technologies, robust features, and user-friendly design make them noteworthy additions to any security setup. Whether it's for large outdoor areas or indoor environments requiring vigilant monitoring, these cameras provide the performance and reliability critical for comprehensive security.
