Biometric Security Explained

February 2nd, 2021

The term biometric can be described as a life measure. Biometrics is used in access and security control applications in Chico CA in order to mean quantifiable physical features of an individual that may be verified on an automatic basis.

Though you may not know it, your driving license includes biometric details about you. Details such as your eye color, hair color, weight, and height are all bodily characteristics which can effortlessly be verified. On the other hand, your height amends as you age. Sixteen year old drivers grow taller, while senior citizens shrink down. The hair color may also change naturally, or on purpose. You may use colored contact lenses which modify your eye color. And lastly, everyone’s weight comes and goes over a period of time.

What kind of biometric data doesn’t change over time? Security people in Chico CA are always searching for biometric data which does not change throughout the course of life. To be exact, they search for bodily characteristics that are invariable and that are hard to change or fake on purpose. But, biometric identification is gradually becoming ordinary as software and hardware slope down in cost.

Biometric Identification

Biometric identification methods may be clustered based on the chief physical characteristic which provides itself to biometric identification:

* Hand Geometry – is the comparison and measurement of the various bodily features of the hand. Even though hand geometry does not possess the same level of individuality or permanence as with some other features, it remains a popular method of biometric identification.

* Fingerprint Identification – The fingerprint ridges are actually created inside the womb. By the 4th month of the fetal growth, a person will have fingerprints. Once formed, the fingerprint ridges are similar with an image on a balloon’s surface. As the individual grows older, the fingers do get bigger. However, the link between the fingerprint ridges is still the same, as with the image on a balloon is identifiable even as the balloon is inflated.

* Palm Vein Authentication – is a system that utilizes an infrared beam in order to go through the person’s hand while it is brandished over the device. The veins inside the palm of the person are read as black lines. The palm vein authentication possesses a high degree of validation accuracy because of the intricacy of the palm’s vein patterns. Since the palm’s vein patterns are inside the body, the authentication system would a hard one to fake. The system does not also need contact. Thus, it is hygienic for utility in public places.

* Retina scan – offers an examination of the capillary blood vessels that are found in the rear of the eye. This pattern stays the same all through life. Retina scans use a low intensity light in order to take a picture of the pattern that is created by blood vessels. This technology was first recommended in the 1930s.

* Iris Scan – offers an examination of the freckles, furrows and rings in the colored ring which borders the eye’s pupil. Over two hundred points are utilized for assessment.

What Our Customers Say

"I had the Alibi system installed several years ago. It has functioned flawlessly. The image quality is exellent both night and day and in all weather conditions. I particularly like the replay (which can be set at various speeds) and zoom functions of the system. Tech support from Crimefreeliving has been excellent. I have received quick responses to questions, and timely home visits — as when I changed IP carriers and my Alibi system needed to be reset. I have recommended Crimefreeliving to several friends."


"As a small business owner here in Chico we definitely saw the need for video surveillance. After expressing our needs and concerns Tim did an excellent job getting us set up with the set up with the appropriate equipment. He really took the time to address our concerns in a very friendly, professional and knowledgeable manner. I highly recommend Tim for all of your business and residential video surveillance needs."

Ron H., Owner/Auto Doctor

"I have to say I love having my security cameras at my home. Tim Truby did a wonderful job of installing the five cameras. He is very neat and cleaned everything up after the installation. He explained to me how to operate the monitor, my phone and IPad. However, I have had to call Tim because I'm not tech savvy and forget what he has told me. He usually just helps me over the phone and then all is well. I'm 80 years old and enjoy the comfort of knowing I have these security cameras."


"Tim Truby designed and installed a 32 camera system for us here at the Butte County Mosquito and Vector Control District. We had received several other quotes from security system vendors, but Tim’s quote was the least expensive. Tim also installed the system quickly and has always been available when we needed him. We are very happy with our security camera system and we can highly recommend Tim Truby for all of your surveillance system needs."

D. Weseman, Butte County Mosquito and Vector Control District

Crime Free Living updated our old video system with a new 16 Channel HD Alibi Video Security System. The old system had been added onto by different installers which resulted in a cabling mess. There were cables that worked and cables that went nowhere. It was a mess. Tim sorted it all out and installed cameras that are very clear. He also installed a monitor for our cashiers to watch hidden areas, a monitor to watch the entry door, and a monitor that allows employees to watch the outside parking and gas pump area. All work was done on time and very professional! Will always recommend Tim and Crime Free Living.

S. AM PM Chico Arco Station

"I had Tim install an Alibi Video Security System at my residence and a couple business locations. The remote view option is invaluable to absentee owners or anyone who travels a lot. The clarity and quality of the cameras have allowed for viewing employee theft. The evidence provided from the HD video cameras was fantastic! Tim was professional and provided extra value from his law enforcement background."

J. Folsom Arco Station

"Tim, I want to thank you again for doing such a fantastic job on installing a wireless IP security camera system at our dream home. The extra time that you took to hide wires, and install a clean, professional system is much appreciated. I still can’t believe the clarity, quality, and ease of use of this new system. I wished that I would have met you before our original inferior system was installed by another company. Now, whether I am at home, or monitoring the system from around the world, I know that my home and family are safe and sound."

John M.

"In April of 2017, my husband and I made a phone call to Crime Free Living that turned out to be a smart and wise decision. Amazingly, in just a few hours, Tim installed four Dome Security Cameras, weatherproof enclosures, and hooked up into our home a 23" Full HD Widescreen Security Monitor. Even more than his professional expertise was the time spent with us in making sure that this system was working correctly and properly installed on our phones so that anywhere in our travels we can monitor our new home in Magalia."

Tieka and Don S.

"I have been using Crime Free Living for the last couple years ar work and at home and I really recommend this product. Tim is a very good service provider. If he can't figure it out, he's got good tech support with the system that he offers."

Gary D.

"I have known Tim for over 10 years. To date, Time with Crime Free Living has installed two separate surveillance systems for my company. With each system, Tim has listened to my needs and custom dsigned surveillance systems for my specific needs and within my budget. The equipment used is always state of the art, the workmanship is top notch, and Tim is the example of trustworthy. I would recommend him for any job."
