Since the development of the Wiegand technology 40 years ago, security solutions have undergone a bold evolution. The past several decades witnessed an impressive transformation in security and access control technologies. Some of the solutions that have emerged in the field include:

  • Wiegand
  • BACnet
  • OSDP — short for Open Source Device Protocol

This rapidly developing technology has had a profound impact across the security sector, particularly in areas related to applications such as:

  • Alarm systems
  • Access control door lock systems
  • Emergency access control
  • Burglar alarms

The evolution of today’s OSDP access control technologies, access control wire, and cable, including Remee’s Vigilance™ line, are explored below.


Evolution of Security — From Wiegand to BACnet and OSDP

Over several past decades, security technology has evolved considerably. Development companies made huge strides — from Wiegand in the 1970s to BACnet in the 1980s and OSDP access control technologies in 2011.

Today, Remee Wire & Cable keeps you up-to-date on all your wire and cable security needs with Remee’s Vigilance™ line of Security, Alarm, and Control Cables.

What Is Wiegand?

The Wiegand technology, developed in 1975, was regularly featured in building card readers as an added level of security. One benefit of the then-novel Wiegand technology was the ability to run long cables from the access control panel to the card readers. Specifically, the Wiegand interface allowed cable runs of up to 150 feet — significantly longer than other interface standards of the time.

The Wiegand interface operated on a binary system that uses zeroes and ones to communicate information in a one-way information feed. It employed three types of wires: one as a common ground and one each to send zeroes and ones.

The Wiegand communication protocol was originally limited to only 26 bits of code, Later, the size limitations of the actual card enforced a maximum of 37 wire filaments, translating to a maximum of 37 bits of code before misreads render the product unreliable.

A 37-bit code length is unimpressive by today’s security standards. Additionally, the information transmitted via Wiegand is not encrypted, and thus, it is not entirely secure, leaving a window for attack. This window of insecurity is considered a major risk. It’s also augmented by the fact that older or preexisting Wiegand Systems are not always compatible with current or new Wiegand systems. This lack of compatibility between older Wiegand systems and new Wiegand systems can prove frustrating for integration.

Over time, Wiegand protocol components became increasingly vulnerable to security breaches. Consequently, the need for improved access control security fueled the development of technologies such as OSDP access control technologies to replace Wiegand.

What Is BACnet Protocol?

BACnet is a communication protocol developed for Building Automation and Control Networks. It is particularly used for communication between building automation services and applications systems such as:

  • HVAC — or heating, ventilating, and air conditioning control
  • Lighting control
  • Access control
  • Window shade controls
  • Fire detection systems and associated equipment

BACnet is a leading building automation and control standard worldwide. Regardless of the particular building services performed, BACnet allows computerized building automation devices to exchange information.

BACnet is also compatible with Wiegand and OSDP, which takes its utility beyond its original scope of HVAC control into the world of physical access control systems (PACS) and security.

What Is OSDP Access Control?

OSDP is used to link together access control systems. Although Wiegand offers one-way communication, OSDP readers are significantly more advanced in their two-way communication offering. This means OSDP readers can both send and receive information. Additionally, the ability to encrypt OSDP communication takes its security rating to the next level.

OSDP was developed in 2008 to increase interoperability among access control products and security systems. Since then, it has grown in popularity because it offers many advanced features to protect systems from security threats.


OSDP Access Control Technologies Versus the Wiegand Technology

When comparing OSDP and Wiegand technologies, there are quite a few differences to consider. OSDP requires less cable, making it less expensive to install. It also has a user-friendly interface, making it less expensive overall. Moreover, its installation and setup are easier than that of Wiegand systems.

While Wiegand requires relatively close proximity between its card readers and access control panels, OSDP offers reader functionality up to distances of 1,200 meters — or 3,937 feet.

On one hand, OSDP can be encrypted — via AES-128 encryption — offering superior security protection from attacks. Wiegand, on the other hand, is comparatively easy to hack with Wiegand data hacking equipment easily accessible for purchase and installation. Additionally, OSDP offers integration with cutting-edge biometric readers and mobile solutions.

Integrating OSDP with Other Protocols

One of the more convenient aspects of OSDP is its ability to integrate seamlessly with applications such as:

  • CCTV and alarm systems
  • Access control door lock systems
  • Emergency access control
  • Burglar alarms

When integrating OSDP with other protocols, you need to choose the right cables. Remee’s Vigilance™ Access Control Cables are recommended for seamless integration technology with a variety of technologies and applications.


OSDP and Vigilance™ Security Cables

If you are looking for high-quality security cables, Remee’s Vigilance™ line offers both standard Plenum-rated security cables and standard Riser-rated security cables.

The Continuing Evolution of OSDP Access Control Technologies

Evolving OSDP Access Control Technologies Security Alarm and Control Cables From Remee Wire and Cable blog photo 2OSDP was first introduced by the Security Industry Association (SIA) in 2011 and later approved as an international standard by the International Electrotechnical Commission in 2020. The SIA also created the SIA OSDP Working Group, which communicates and exchanges information with other engineers and field experts to further the development of OSDP technology.

The SIA is dedicated to continuing the evolution of OSDP technologies to keep pace with security requirements worldwide. Having an organization focused on developing OSDP access control technologies helps to ensure that OSDP will remain the global standard long into the future.
