Biometrics - The Latest Technology In Home Security

Any homeowner who has purchased their home with an already-installed security system can feel like they have won the lottery. After all, there's no need to spend all that extra money on having a system installed. And there's also no need to do all of the legwork involved with finding the right system. All that's needed is to choose a security company for monitoring, and you are protected. Or are you?

The truth is that no home security system can protect you 100%. And that security system that may have been installed when you moved in? It could very well be outdated. Technology is evolving at breakneck speeds, and the advances in home security are no exception. One new method, biometrics, is taking the security world by storm.

What Biometrics Do

Simply put, biometric security systems allow a person to enter into a structure, such as a house, following successful identification by referring to a specific genetic marker. Most often, this marker is a fingerprint. Now two human beings have the same fingerprint, making this form of identification very suitable for home security applications.

Biometric Identification Vs. Biometric Verification

There are two ways in which biometric security units are offered; they will either identify or verify. A biometric home security unity that identifies individuals will do so by comparing fingerprints to others in a database of various biometric templates. Matching markers will result in granted access to a property.

In biometric verification, a test is performed on any individual wanting access to a property. This test will involve comparing the fingerprint of the individual with the fingerprints of those previously stored in the database of the unit. In verification, the genetic markers may vary, and include voice verification or other markers.

Common Components Used By Biometric Systems

In addition to fingerprint and voice identification and verification, biometric systems involve a number of other components. Retinal or iris scans employ lasers to read the unique attributes associated with the eye's components.

The signature analysis considers the force, speed and direction a writing implement produces when a particular individual uses it. Thermal imaging involves the analysis of the blood vessels located under the skin. The features of each person's facial blood vessels vary greatly, even between twins. In addition to the print of a finger, the length of a finger is another biometric component that can be measured, due to the fact that no one finger's length can be exactly the same as another's.

Why Install A Biometric Home Security System?

The benefits of installing a biometric home security system are many. First of all, this type of system can quickly identify an individual, unlike other systems like card readers, which may not be able to read a card from time to time.

A biometric home security system also frees you from having to carry additional accessories, such as a key fob or card. This eliminates the possibility of not being able to enter a residence, as one's biometrics travel with them everywhere.

Biometric systems are also very non-intrusive. They can be installed virtually anywhere in a home. As well, a biometric system can also provide the homeowner with additional information, such as when the person entered the home, and how long they remained in the home. Biometric systems also don't require the hiring of a security firm.

What To Consider When Looking For A Biometric System

Some important performance characteristics when shopping for the right biometric system include the FAR, or false accept rate of a unit. This measurement indicates how likely a system is to be able to match a characteristic incorrectly. The lower the FAR, the better a biometric security system will be at correctly identifying individuals on a regular basis. Another characteristic is the false reject rate, or FRR, which is a security unit's probability of incorrectly rejecting the supplied biometrics of an individual.

The capacity of any given unit will matter to anyone seeking to purchase a biometric security system. Experts recommend that homeowners leave a lot of space as far as the database of fingerprints or other characteristics are concerned. This will mean that more individuals can be stored in your database, meaning a greater number of positive identifications for those wishing to enter your home.

Whichever system is chosen, it's important that all system components have been reviewed. This will help you to avoid a less-than-quality product.
