26-Bit Wiegand Format & Work

26-Bit Wiegand Format & Work? 

The name “Wiegand” comes from its creator, the German-born engineer, John R. Wiegand, who in the 1970’s discovered that wires made of a cobalt, iron and vanadium alloy will switch polarity when run through strong magnetic fields. Placing a sensor coil nearby will be capable of picking up the change in polarity as a high-voltage pulse, and then translate that pulse into data. He used these discoveries to create what became known as Wiegand wires and Wiegand cards.

A Wiegand card uses two short wires, which store data magnetically in the card; these two wires are known as Data low, or Data0 and Data high, or Data1. When the card is pulled through the reader, the wires transmit the either high or low voltage signal as 1 and 0’s, respectively, creating a binary data line for authenticating the swipe card’s credentials. (There actually is a third wire, as well, providing common ground).

There are a few different variations of the Wiegand protocol in existence, but the original is the most common, known as the 26-bit Wiegand format, or often just the 26-bit format. This is a very common open format, meaning that virtually anyone can buy compatible cards and readers and program them to work using the 26-bit Format. It uses one parity bit, followed by 8 bits of facility code, 16 bits of ID code, and another trailing parity bit, for a total of 26 bits. This was the standard for a long time and remains in use in many systems, though a variety of different extensions have now been built off it.

Card readers and other components of access control systems need to speak a common language to function and work properly. Like most other forms of technology, access control systems use a binary number system to communicate. One of the most common formats for access systems is the 26-bit Wiegand format. It was first developed over 50 years ago, and because it’s so simple and accessible, it’s still used today.

What is the 26 bit Wiegand format, how does it work, and where is it used? Learn more below. 

What is 26-Bit Wiegand Format? 

The 26-bit Wiegand format is a format for binary encoded data used mainly on access control devices. It’s an extremely common open format, and most access control systems are automatically designed to be able to read 26-bit Wiegand. Because it’s an open format, anybody can buy and use cards in this format, and it is possible for duplicate cards to exist.

Although various companies make access control systems, one of the most popular brands is HID. The brand is so popular that people often refer to any access control system as an HID system. However, various brands and manufacturers make 26-bit Wiegand format access cards, not just HID. If you buy or use any basic access system, it’s highly likely that the system runs using the 26-bit Wiegand format.

Key Features of the 26-Bit Wiegand Format

1. 26-Bit Data: The format consists of 26 bits, divided into three parts: 8 bits for the facility code, 16 bits for the card number, and 2 bits for parity.
2. Facility Code: The first 8 bits represent the facility code, which identifies the site or organization.
3. Card Number: The next 16 bits represent the card number, which is unique to each cardholder.
4. Parity Bits: The last 2 bits are parity bits, used for error detection.
5. Even/Odd Parity: The parity bits use even/odd parity, where the first parity bit is the even parity of the first 12 bits, and the second parity bit is the odd parity of the last 12 bits.

This format is an industry standard known as H10301. The term “bit” refers to the numbers in the code, so each code consists of 26 numbers. Wiegand refers to the Wiegand protocol, which is the name for the wiring standard. It’s named after John R. Wiegand, whose discoveries in the 1970s laid the basis for the standard 26 bit format. 

The first and last numbers in the 26-bit Wiegand format are beginning and ending bits known as parity bits. They are not part of the unique identification laid out in the code. Bits two through nine make up the facility code. The facility code consists of eight bits. Bits 10 through 25 make up the ID number. The ID number consists of 16 bits. 

Here is how the code in 26-bit Wiegand appears when P stands for parity bit, F stands for facility code bit, and I stands for ID number bit: 

PFFFFFFFFIIIIIIIIIIIIIIIIP

The 26-bit Wiegand format allows for 256 possible facility codes and 65,535 possible ID numbers. When combining both unique identifiers, this allows for 16,711,425 unique access cards.

The 26-bit Wiegand format consists of a sequence of 26 bits, divided into three main parts:

·        Facility Code (FC): The first 8 bits (bits 1-8) represent the facility code, which identifies the specific facility or organization issuing the card.

·        Card Number (CN): The next 16 bits (bits 9-24) represent the card number, which is unique to each cardholder.

·        Parity Bit (PB): The last 2 bits (bits 25-26) are parity bits, used for error detection.

Rather than being written out with numbers or letters as in the example above, the code is represented in an access card or other access device with a series of wires. We’ll explain more about how that works below.

How Does 26-Bit Wiegand Format Work? 

Back in the 1970s, Weigand discovered that cobalt, iron, and vanadium alloy wires switch polarity when they enter a magnetic field. He also found that sensor coils can pick up the change in polarity. This laid the groundwork for the modern Weigand protocol where access card readers are able to translate and read the code that lies hidden in the wires inside access devices. 

26-bit Wiegand access cards have three wires inside: data low (data0), data high (data1), and a ground wire. Because binary numbers are expressed as 0 or 1, data0 and data1 are used to create those binary numbers that the access control system can read. When the data0 wire transmits a signal, the computer reads it as 0, and when the data1 wire transmits a signal, the computer reads it as 1. The wires are uniquely designed to create a different code for each cardholder.

When a device that’s encoded with the format passes through the field of a card reader, it picks up on the unique sequence of bits contained in the device. Then, it grants access if the facility code and ID number in the device are allowed access. Of course, the system can also deny access if the code in the card or other access device does not match an approved code.

Here's a step-by-step explanation:

1.   Card Swipe: A user swipes their access control card through a reader.

2.   Data Extraction: The reader extracts the 26-bit Wiegand code from the card's magnetic stripe or RFID chip.

3.   Bit Transmission: The reader transmits the 26-bit code, one bit at a time, to the access control panel or secure authentication device.

4.   Bit Representation: Each bit is represented by a specific voltage or signal level, with 0 volts typically representing a binary 0 and 5 volts representing a binary 1.

5.   Data Format: The 26-bit code consists of:

·        Facility Code (8 bits): Identifies the facility or organization issuing the card.

·        Card Number (16 bits): Unique to each cardholder.

·        Parity Bits (2 bits): Used for error detection.

6.   Authentication: The access control panel or secure authentication device verifies the received 26-bit code against stored data, ensuring the facility code, card number, and parity bits match.

7.   Access Decision: If the verification is successful, the device grants access or performs the desired action.

Where Is the 26-Bit Wiegand Format Used?

The 26-bit Wiegand format is most often used in standard access control systems. You’ll find wires corresponding to the 26 bits in access cards, key fobs, fingerprint readers, and other access control devices. 

The data on a standard Wiegand-formatted device is not encrypted. This, of course, presents a vulnerability and is one of the reasons this format has lost some of the popularity it previously held. It’s also possible for duplicate 26-bit Weigand access devices to exist, which is a major concern for industries that highly value security. 

You’ll often find access control systems that use the 26-bit Wiegand format in older buildings because it was once the gold standard. Unless there is a malfunction in the equipment, there isn’t often an immediate need for companies to upgrade to a different format even though the 26-bit Wiegand format is becoming a bit outdated. It still works very well for most use cases. 

However, newer buildings and newer access control systems are beginning to favor different formats, such as Open Supervised Device Protocol (OSDP). This can increase security because it is encrypted. For this reason, you’re also less likely to find 26-bit Wiegand formats in buildings and campuses where security is of utmost importance.

Nonetheless, the 26-bit Wiegand format is still used today for many reasons. It’s easy to use, it’s readily available, and most card reader door locks and access control systems are equipped to read the format. If you purchase or install an access control system and you don’t specify or request a particular format, it’s likely your system uses the 26-bit Wiegand format.

Advantages of the 26-Bit Wiegand Format

1. Wide Compatibility: The 26-bit Wiegand format is widely supported by access control systems and RFID readers.
2. High Security: The use of parity bits and a large data format provides high security against data tampering and unauthorized access.
3. Easy Implementation: The 26-bit Wiegand format is easy to implement and integrate with existing access control systems.
4. Scalability: The 26-bit format provides a large address space, allowing for a high number of unique card numbers and facility codes.

Limitations of the 26-Bit Wiegand Format

1. Limited Data Capacity: The 26-bit Wiegand format has limited data capacity, which can make it difficult to store additional data, such as biometric information.
2. No Encryption: The 26-bit Wiegand format does not provide encryption, which can make it vulnerable to eavesdropping and data interception.

Animals Accidents Reduction Using AI

Animals Accidents Reduction Using AI 

Every species on Earth is important. They all play a role in keeping our ecosystems balanced. But now, these delicate balances are being threatened. Habitat loss, climate change, poaching, and illegal wildlife trade are just some of the problems wildlife face. We need to find new and effective ways to protect wildlife. The situation is urgent.

Stray animals are a growing problem in cities around the world. They are unable to find food and shelter, so due to that, they stay on roads, which present a dangerous hazard to road traffic and pedestrians alike. But today stray animals accident reduction using ai is possible. AI Video Analytics Software is capable of detecting stray dogs and other animals and capable of stopping accidents caused by stray dogs.

According to the data, there are 1,376 accidents caused by animals, which involve 804 dogs and 350 cattle. We often blame bad roads for road accidents and injuries, but nowadays the second most common reason for road accidents and injuries is stray animals. Stray animals are not the problem; these innocent animals are not getting proper shelter and food to survive, and for that reason, they have to come on the road in search of food and shelter.

To address this issue, many cities are turning to artificial intelligence (AI) video analytics to detect and alert municipal and animal health care departments. They can then respond to the alert by sending out animal health care workers to take care of the stray animals. By using stray animal detection, cities can help prevent accidents and injuries due to animals on the roads and promote smooth mobility.

An AI video analytics solution uses real-time data from sensors, cameras and GPS systems to prevent accidents. These can be accidents on the road by colliding with another vehicle or animal-related collisions. Especially at night, AI can easily detect animals from far an warn the user or the driver.

Alstom has together with Flox received SEK 3.3 million (EUR 290.000) in funding from Vinnova to conduct field tests of a groundbreaking AI system that prevents collisions between trains and wildlife. Every year, Trafikverket reports around 5,000 animal collisions in Sweden, and by reducing both accidents and damage to train vehicles while protecting wildlife, the project has the potential to revolutionise railway safety.

Harnessing the Digital Beast: AI in Wildlife Conservation and Control

In the vast wilderness of our planet, a new ally is emerging in the fight for wildlife conservation and control. This ally is not a new species discovered in the depths of the Amazon or the heights of the Himalayas, but a product of human ingenuity and technological advancement: Artificial Intelligence (AI). As we delve into the myriad ways AI is being utilized in wildlife conservation and control, we will explore how this digital beast is helping us understand, protect, and manage the diverse array of life that shares our world. From the depths of the oceans to the vast expanses of the African savannah, AI is revolutionizing our approach to conservation, providing us with tools and insights that were once beyond our reach.

Car Accidents Caused By Animals Statistics

·        According to the data mentioned earlier, majorly road accidents in India occur due to stray animals.

·        And it is the second-most common reason for accidents.

·        Stray dogs are responsible for 62% of animal accidents in India.

·        Cows and Buffaloes share 29% and 4% respectively of animal-related accidents.

Stray Animals Accident Reduction Using AI

·        In the monsoon and winter seasons heavy rain and fogs are two major reason that add up to animal-vehicle collision. The driver cannot see the animal on the road until the car gets really close to it.

·        By the time the driver tries to dodge or applies brakes – it is too late.

·        Therefore, an animal detection AI solution is the key to this problem.

·        Whether its day time, night time, foggy day or heavily raining, AI can easily detect stray animals on the road no matter however unclear the vision is for humans.

·        A perfect AI Video Analytics Solution that can detect stray animals on the road before well before the vehicle reaches a collision.

Benefits of Stray Animal Detection

·        Swift Alerts: An AI-enabled guardian is highly active, has a close watch to detect stray animals, and sends alerts in real time so that the respective authority can be alerted. No stray animal was left unattended.

·        Enhanced Safety and Mobility: With stray animal detection, our streets are safer for everyone. Accidents and injuries, often caused by unexpected encounters with stray animals, have dropped significantly. It also makes traffic flow smoother, making our streets safer and more efficient.

·        Empowering the Visually Impaired: Stray animal detection helps people who are blind or visually impaired navigate their surroundings safely by alerting them to the presence of stray animals so that potential hazards posed by stray animals can be avoided.

CAT cable to wire CCTV cameras

Using CAT cable to wire CCTV cameras 

In recent years the invention of the video balun has meant CAT cable can be used to connect CCTV cameras to CCTV DVR recorders. All the connections can be made using only a screwdriver, with no need for special tools or fiddly components. Before you start there are a couple of important things to know.

What components do I need?

Video is transmitted along the CAT cable using a pair of video baluns, one at the DVR end, and one at the camera end. We sell 2 types of video baluns, Standard definition and High definition designed to be used with our HD 1080P cameras and DVR recorders. Power is transmitted using screw-in DC plugs and sockets. The plug goes at the camera end and the socket at the DVR end. Locate the camera power supply close to the DVR.

Use the correct type of CAT cable

You must use pure copper CAT cable. Some CAT cable is not pure copper but CCA or copper-coated aluminium. Don't rely on the label or what the retailer says, actually check the cable yourself. CAT5, CAT5e, CAT6 and CAT6e can all be CCA rather than pure copper. CCA tends to break easily when bent and you can scrape the copper off to reveal silver-coloured metal in the centre. All the cable we sell is pure copper external grade.

Don't exceed the maximum cable run

The maximum distance video signal can be transferred with our video baluns is approximately 300 metres. If you are using the cable to power a camera as well as transfer video signal then we would suggest a maximum distance of about 50 metres to avoid voltage drop. This assumes you are using 3 pairs of wire for 12 volt supply and 1 pair for video signal transfer as per our images below.

Use a colour convention, stick to it and check carefully

It is important to check your wiring carefully. Choose a colour convention and stick to it. In the examples below we have used blue for the video signal and solid colour for +ve, white plus a coloured stripe for -ve.

You need to run 1 length of CAT cable from the DVR recorder to each camera. The cable is going to do 2 jobs. One pair of wires will handle the video signal, and the other 3 pairs of wires will be combined to take 12-volt power from the transformer located next to the DVR to the camera.

Firstly identify the polarity for all your connectors

Separate the 4 pairs of wires in the CAT cable. In this case, we are going to use the blue pair for transferring the video signal from the camera to the DVR. Keep this pair twisted, to reduce the chance of interference.

The green, brown and orange pairs are going to be used to take 12-volt power from the transformer to the camera. We use 3 pairs of wires combined to reduce the risk of voltage drop at the camera. Having unwound the wire use the solid colour for 12-volt +ve and the white with coloured trace for 12-volt -ve.

Here we can see the cables inserted into a video balun and a power plug.

Remember to strip back the outer plastic sheath to reveal the copper conductor before pushing into the fittings and tightening the connector with a small screwdriver.

Note how we have combined the 3 pairs of wires for the 12-volt DC fitting.

Be aware the DC power fittings are different for the DVR end of the cable and the camera end of the cable. The DVR end requires a female socket to take the 12-volt power from the power supply.

The camera end requires a male DC plug To take 12-volt power to the camera

It is important to protect the fittings from water so we recommend using weatherproof junction boxes for each camera. All the components you need are available in the CCTV accessories section of our online shop.

You can use Cat5 and Cat6 cables together in the same CCTV system.
