Types of Access Control Systems

There are many different varieties of access control devices and systems used for different purposes. If you are looking to use an access control system for commercial or residential use, there are many forms of access control devices available to you. An access control system gives users access and authority to manipulate certain areas or resources in a specific facility or pc within the control of the owner.

It is an everyday thing we are normally oblivious to, but they are everywhere we go. A few examples of access control systems are locks on the automobile door much like your key fob to automatically lock and unlock your automobile. Another form of access control will be your pin on a debit card or perhaps bouncers in front of your nightclub or courthouse. Access control can be quite a significant resource when people are looking to safely secure confidential or sensitive information or equipment.

There are numerous access control devices from which to choose. The types of door hardware include exit devices and push bars which are used when exiting a top-notch traffic building say for example a theater. You typically see exit devices as a possible emergency exit which allows exiting easily and immediately. Other door hardware devices include keypads and alarm locks that secure a unique area to prevent theft and break-ins. Appears to be unauthorized user gains access, then an alarm will go off and away to warn those inside building. A keypad can be used to restrict use of unauthorized users that needs an access code or password to appreciate entry.

A different sort of door hardware which can be used for access control are vault doors. The objecive of a vault door will be to safely secure not merely personal heirlooms, weapons or guns, business and family records, photographs, jewelry, art, collectibles and rare antiques. A vault door is usually constructed beyond thick steel barrier to protect against extremely hot temperatures plus thick bolts to ensure your valuables feel safe. Vault doors can also be used as a storm shelter, notably if you live in a place where hurricanes, tornadoes and weather conditions are persistent.

Other sorts of access control are push buttons. You mainly see push buttons found in case of the emergency or even the handicapped. Push buttons are hard to miss being that they are larger than normal buttons this will let you bright red color. The same costs handicapped buttons but you are indicated with all the ordinary handicap blue color. These push buttons are usually seen at hospitals or buildings with high person traffic offering easy entry and exiting through your building and never have to physically push or pull the threshold.

You will also see various kinds of access control locks like electric strikes and magnetic door locks. Electric strikes are always used for doors that apply electricity for the strike, that will grant access. There is a couple of forms of configurations such as fail-safe or fail-secure. A fail-secure configuration will lock the doors and grow locked in case of the power or circuit failure. The alternative applies to a fail-safe configuration where an electric current is applied exactly the same except it locks the edge, restricting access. In the power or circuit failure the doors would simply open for access. Sometimes electric strikes use a buzzer, which the user outside can hear if the door is open.

For magnetic door locks you will find electromagnets that affix to the doorframe as well as the door itself that create the door to securely shut tight. The potency of the magnetic locks is useful like your typical door lock. Together with the magnetic attractive force, magnetic locks usually takes up to 1200 pounds of force and they are very compact. Some magnetic locks are available with an infrared remote release to allow entry.

Intercoms are a fantastic access control device. They provide the benefit of communicating out user through another intercom device or phone without having to walk up to the entranceway to check on. Intercoms are typically mounted beyond a residential apartment building, which are usually vandal and safe from nature’s elements. With intercoms you’ve got different stations for many users. Some intercoms feature over two stations or maybe a monitor so that you can see that you might be talking to.

Whether you’re looking for an access control device for your home or business, it is very important have one to safeguard not only your valuables, but in addition your family members and employees in case of a break-in or intruder. There’s a wide selection of access control devices for example card readers, digital locks, key switches, keypads plus more available to you determined by what you need. Take time to see which technique is the right one for you and you’ll be soon along staying safe and sound.

Biometric Scanner Installations Sacramento

There is a wide variety of biometric scanners and integration techniques. Below we have broken down the different types of biometric scanners. If you have any questions contact us at (916) 550-4386


Biometric Retina Scanner

The human retina is a thin tissue made up of neural cells that is based in the posterior portion of the eye. Due to the complex structure of the capillaries that supply the retina with blood, every person’s retina is unique. The network of arteries in the retina is not entirely genetically determined and so even identical twins usually do not share a similar pattern.

Although retinal patterns may be altered in cases of glaucoma, retinal degenerative disorders or diabetes, the retina typically remains unchanged from birth until death. Because of its unique and unchanging nature, the retina seems to be the most precise and reliable biometric, in addition to DNA. Advocates of retinal scanning have figured it is so accurate that its error rates are estimated to be only one inside a million.

A biometric identifier termed as a retinal scan is used to map the patterns of a person’s retina. The bloodstream within the retina absorb light more readily than the surrounding tissue and are easily identified with appropriate lighting. The system performs a retinal scan by casting an unperceived beam of low-energy infrared light in to a person’s eye as they look through the scanner’s eyepiece. This laser beam traces a standardized path about the retina. Because retinal blood vessels are more absorbent on this light than the rest of the eye, the volume of reflection varies during the scan. The pattern of variations is transformed into computer code and held in a database.

Biometric Iris Scanner

Iris recognition is definitely an automated method of biometric identification that utilizes mathematical pattern-recognition techniques on video images of the irides of an individual’s eyes, whose complex random patterns are unique and can be seen from some distance.

Never to be confused with less prevalent, ocular-based technology, iris recognition, retina scanning uses camera technology with subtle infrared illumination to acquire images of the detail-rich, intricate structures in the iris. Digital templates encoded from these patterns by mathematical and statistical algorithms enable the identification of an individual or someone pretending to be that individual. Custom databases of templates are searched by matcher engines at speeds measured from the millions of templates per second per CPU, sufficient reason for infinitesimally small false match rates.

Many millions of persons in several countries around the world have been enrolled in a iris recognition system, for convenience purposes such as passport free automated border crossings, and some national ID systems determined by this technology are being deployed. An integral advantage of iris recognition, besides its speed of matching as well as extreme resistance to false matches, will be the stability of the iris as a possible internal, protected, yet externally visible organ with the eye.

Biometric Fingerprint Scanner

Finger Scanning, also known as fingerprint scanning, which is the process of electronically obtaining and storing human fingerprints. Digital image obtained by such scanning is termed a finger image. Some texts say, the terms fingerprinting and fingerprint are widely used, but technically, these terms reference traditional paper and ink processes and images.

Finger scanning is really a biometric process, because it requires the automated capture, analysis, and comparison of the specific characteristic of the human body. There are a variety of different ways in which an instrument can bring out the details in the pattern of raised areas (called ridges) and branches (called bifurcations) in a human finger image. The most frequent methods are thermal, optical, and tactile. They work using heat emission analysis, visible light analysis, and pressure analysis, as applicable.

Biometric finger scanning offers improvements over ink-and-paper imaging. A whole set of finger scans for an individual (10 images, including those of the thumbs) can be distributed, easily copied, and transmitted over computer networks. Also, computers can quickly analyze a finger scan and compare it with thousands of other finger scans, along with with fingerprints obtained by traditional means and after that digitally photographed and stored. This greatly accelerates the process of searching finger image records in criminal investigations.

Biometric Facial Recognition

Some facial recognition algorithms identify facial features by extracting landmarks, or features, from a graphic of the subject’s face. By way of example, an algorithm may analyze the relative position, size, and/or shape of the eyes, nose, cheekbones, and jaw. These traits are then used to search for other images with matching attributes. Other algorithms normalize a file of face images and then compress the face data, only saving your data in the image that is ideal for face recognition. The probe image is then compared with the face data. One of the oldest successful systems is based on template matching techniques applied to a set of salient facial features, providing some type of compressed face representation.

Recognition algorithms should be divided into 2 main approaches, geometric, which examines distinguishing features, or photometric, the statistical approach that distills a picture into values and compares the values with templates to eliminate variances.

Popular recognition algorithms include Linear Discriminant Analysis, Principal Component Analysis using eigenfaces, Elastic Bunch Graph Matching with all the Fisherface algorithm, the Multilinear Subspace Learning using tensor representation, the Hidden Markov model, and also the neuronal motivated dynamic link matching.

3-Dimensional Recognition
The newest wave, claimed to achieve improved accuracies, is a three dimensional face recognition. This system uses 3D sensors to capture information about the shape of a face. This data is then used to identify distinctive features at first glance of a face, such as the contour from the nose, eye sockets, and chin.

One benefit from 3D facial recognition is that it is not affected by changes in lighting like other techniques. It may also identify a face from the range of different viewing angles.

Three-dimensional data points coming from a face vastly improve the precision of facial recognition. 3D research is enhanced with the development of sophisticated sensors which do a better job of capturing 3D face imagery. These sensors work by projecting structured light to the face. Up to a dozen or higher of these image sensors may be placed on the same CMOS chip-each sensor captures a different part of the spectrum. Even a perfect 3D matching technique might be sensitive to expressions.

Skin texture analysis
Another trend uses the visual information the skin, as captured in standard digital or scanned images. This technique is called skin texture analysis, turns the unique patterns, lines, and spots apparent within a person’s skin into a mathematical space. Tests demonstrate that with the addition of skin texture analysis, performance in recognizing faces can increase 20 to 25 %.

Biometric Voice Recognition

Speaker recognition will be the identification of the person who is speaking by characteristics of their voices (voice biometrics), also called voice recognition.

There is a difference between speaker recognition (recognizing that’s speaking) and speech recognition (recognizing precisely what is being said). These two terms are generally confused, and “voice recognition” can be used for either. In addition, there is a difference between the act of authentication (commonly referred to as speaker verification or speaker authentication) and identification. Finally, there exists a difference between speaker recognition (recognizing who is speaking) and speaker diarization (recognizing if the same speaker is speaking).

Recognizing the speaker can simplify the job of translating speech in systems which have been trained on specific person’s voices or quite a few to authenticate or verify the identity of a speaker as part of a security process.

Speaker recognition features a history dating back some 40 years and uses the acoustic top features of speech that have been found to differ between individuals. The acoustic patterns reflect both anatomy (e.g., decoration of the throat and mouth) and learned behavioral patterns (e.g., voice pitch, speaking style). Speaker verification has earned the speaker recognition in its classification like a “behavioral biometric”.
