How Facial Recognition Technology Works To Provide Security

April 9th, 2019



As security technology advances in Houston, TX, biometric identification solutions are becoming more prevalent. One of the most technologically-advanced forms of biometrics is facial recognition technology (FRT). FRT analyzes the unique features of an individual’s face and verifies their identity. FRT can be utilized for authentication of identity for access to sensitive areas or information. FRT is extremely reliable and is likely to become very commonplace for businesses in TX in the near future.

How FRT Works To Establish Identities

When trying to understand FRT, there are two pieces to understand. First is the technology that scans the facial features. This technology can be a combination of sensors, video recorders, and scanners. The second piece is the analyses of these unique features that uses a combination of database and analytics software. Basically, FRT takes a scan of your face that is cross-referenced with a database to authenticate your unique identity.

The Most Common Types Of FRT

Currently, there are about four types of FRT available to the public in Houston, TX. These range from the commonplace FRT used by Facebook and your smartphone, to highly advanced FRT used at the most secure buildings around TX. Here are the most common types of FRT:

  • Traditional: Traditional FRT uses a photograph or image of a face and analyzes the basic geometry of the features. Once these features are analyzed, they are cross-referenced against a database of different faces.
  • 3-Dimensional (3D): 3D FRT is more sophisticated and uses 3D sensors and cameras positioned at multiple angles. The sensors capture the shape and contours of the face, while the cameras capture the traditional FRT data. The traditional FRT data is then overlaid over the 3D sensor data to create a comprehensive understanding of the facial including different facial expressions. This data is also cross-referenced with a database for identification.
  • Surface Texture Analysis: Surface texture analysis takes an image of a patch of skin, called a skin print. This skin is then segmented and turned into measurable space with complex algorithms. The skin print is then analyzed for any lines, pores, or interesting characteristics of the skin. Surface texture analysis is used in tandem with traditional and 3D FRT and can distinguish between identical twins.
  • Thermal: Thermal FRT uses the same basic concept as other FRT. However, the cameras used are far more sophisticated. Thermal FRT uses traditional cameras and thermal video cameras to create facial recognition in low visibility scenarios.

Most FRT used in Houston, TX utilize a combination of these four different technologies.

FRT is a great technology to consider for your business security needs. FRT is automatic and can be set up without training your staff or guests. It works with existing databases like passport and TX driver’s license photos. Also, it’s easy to set up because outside of the truly sophisticated FRTs, your existing surveillance cameras can capture the data needed to be effective. FRT can be used at an entry point and throughout your business campus.

"Steve I just wanted to thank you and your partner Ray Kindsfather for the fine work you men did installing the security cameras around my home. The quality of the pictures is excellent, the clarity in day or infrared mode is exactly what I was looking for. What good is a camera if you can't identify the person and these cameras will greatly assist the police in identifying a perpetrator. The computer side of the job is easy and fast with very little adjustment time for me in finding what I want to see. Software and hardware get A+++++ no doubt about. The Ring is equally easy to use and the quality of the camera is equally strong. The installation was clean and fast. You maintain a clean site, it’s like you were never here. You answered all my questions with pin point accuracy. Integrity suits you well. Your answers were honest and to the point. Refreshing in today’s world. All and all you and Ray make a strong team at DWS Technology LLC. I have no problem recommending you to friend or family, home or business. God bless you both with your business. I will call you for future installations. "

"Ray, in reviewing several different security cameras there were many good products, but none met my criteria of clarity and no long-term contract. Raymond, you showed me one product that caught my attention with the clarity and distance viewing that I could not get with other systems. The zoom after a few feet became distorted with the other systems but with the Alibi NVR package you demoed, we could zoom in and out with clarity which made this product stand out from all the rest. The NVR system is so simple, in fact, anyone can configure the system to suit their needs. You can monitor your home from your smartphone or tablet and having security cameras makes it a great deterrent for criminal activity. DWS Technology delivered as promised! Your installation crew worked clean and treated my home as if it was their own. Great attention to detail! I will recommend DWS Technology to anyone! Great job guys!"
