Types of Biometric System

Biometric system is the name of advance security method that is used to bring systematization and high level security at different places like business organizations, buildings, threatening areas and many other commercial and residential areas. These systems help us to maintain the much-deserving security level.
Mostly biometrics systems usually perform their work by recording and comparing biometric characteristics. The data might be in the form of images, voice recognition, signatures or time series data. For efficiency reasons, rather than using recorded characteristics directly, it is usual to extract identifying features from the samples and encode these features in a form that facilitates storage and comparison.
When a person uses any kind of biometric system or facial recognition for the first time, his identifying features stored in the system as a reference for his/her future judgment. When a person once again use this system the computer recall its initial indentifying feature and compare it with current identifying feature to determine whether he/she is a same person or not.
Basically there are two modes for biometric recognition: verification and identification. In verification, access control solutions an identity is required and the comparison procedure is just restricted to checking the reference corresponding to this identity. But in identification, no claim is required and the system searches its orientation database to locate if a stored reference matches the biometric characteristics recorded. There are many types of biometric system available; some of them are given below:
Face Recognition Biometric System
Each individual have different face that belongs to different cultures, races, genders and geographical locations. Face recognition system use unique points of the face and use them for comparing or authentication process. When a person comes in front of the face recognition camera, the system captures its face image without informing that person in its database for future identification. Today, many high standard companies, banks and many security departments use these systems for advance security measurements.
Fingerprint Analysis Biometric System
This is the most common form of biometric system. In this process the system indentifies the person through his/her thumb, figure or palm prints. You can easily find this technology in electronic commerce, law enforcement, computer and laptops.
Voice Recognition Biometric System
Voice recognition biometric system record the sound of the person and store it in its database. Normally, the voice recordings and voiceprints are used as for password to authenticate their entry to various places.
Other Biometric Systems in the Market
• Hand geometry recognition based biometric tools make use of dimensions, surface area and shape of hands and are used for residential as well as commercial purposes.

- Data are protected electronically, that eliminates the risk of unusual tampering of data and causing any unnecessary damage, cctv surveillance systems which provides better security.
Visitor Management System:
Face-recognition based visitor management system is an effective device that is implemented in premises to control the unauthenticated visiting of the visitors. The two exclusive features of visitor management system that makes it special can be listed as follows:
- It notifies the exact in-timing and out-timing details of the individuals in the premises. It helps in monitoring the arrivals access control solutionsand departures of the entities in the organization.
- It also supports the alarm facility that blows when an unauthenticated individual re-visits the premise. The alarm is set by the authority based on the priority for signaling threat to others.
These are the major benefits one can receive, if they implement biometric time attendance system, biometric access control system and visitor management system in the premise. So would you like to become one of them?

How IP Video Surveillance Cameras Work

If you talk about one of the most powerful and best physical security then IP Video Surveillance and Network Video Recorders (NVRs) are two of the most common terms that are used for IP cameras and network based cameras. Almost every kind of IP video surveillance cameras and NVRs are based on different kind of software applications, the software functionalities can vary significantly. These variations are This variance can appear between suppliers and even amongst supplier's offerings. For instance many providers offer a number of options. Examples of categories include:
• Basic: small camera systems, basic functionality
• Medium: medium camera systems, more advanced camera and system controls
• Multi-Site: large camera systems with servers in multiple locations
• Global: super-large camera systems with failover and central management
IP surveillance cameras are expected to be in high demand in the near future. Banks, retail shops and several other professional organizations and individuals are opting for video intelligence systems protection. Advancements in digital technology have made video surveillance system cost effective, flexible and easily operable. Security systems that utilize Internet Protocol (IP) cameras are easy to fix, maintain and customize.
Initially, video surveillance was based on analog technology, meaning closed circuit television and video tape recording. However, it was not a practical solution for monitoring stores from a remote location, since it did not broadcast live information. The picture quality was poor and was dependent on human interference.
In the 1990s, digital technology revolutionized the surveillance system. Analog camera tubes came to be replaced with Charged Coupled Devices (CCDs). Digital cameras became very affordable for most. This combined development signified two things:
• It became possible to upload and download camera feed online. Thus, remote surveillance came into existence.
• With CCDs it was possible to generate high resolution images which could be manipulated for further processing.
For law enforcement, the use of digital technology proved ideal since zooming in, tracking specific scenes and enhancing features became easier.
A digital camera first captures the scene, broadcasts the images as digitized signal over a Local Area Network or LAN, where it is transmitted to a server. The server manages all the information. Relying on the software being used to manage the images, the server can record or display the images anywhere in the world.
The software package can be customized for facial surveillance including analyzing data and selecting 'flagged' items. With this technology, it is possible to send video files as data packets over the LAN. For exhaustive security solutions, the data available through the IP surveillance technology can be encrypted to prevent malicious activities such as data tampering.
