4 Biometric Door Control Systems to Consider

Posted by & filed under .

The use of a sophisticated door access control system is becoming popular in offices and public buildings in Singapore. These are usually integrated with other security and monitoring systems such as the IP camera and intercom solution to better protect property and occupants.

A pin access door system, however, is prone to a lot of problems, while the card access door system can be easily bypassed, and the key cards stolen or lost. Therefore, there is a growing demand for another type of door access control system, the biometric door access system, which eliminates common problems. This is one way to secure authorized entry before it can unlock glass doors in your Singapore office. Improving your gate security system can ensure better safety and security.

What is a Biometric Sensor?
The most important part of the system is the biometric sensor which converts biometrics into electrical signals. The biometrics are measurements and analysis of a person’s physical and behavioral characteristics. This type of track access entry uses a sensor for different types of biometrics. This means that a security camera such as a conventional CCTV IP camera can be used for facial recognition, while the microphone for the intercom system can be utilized for voice recognition. This is helpful for your office in Singapore when you want a secure way to capture security breaches.

Other buildings integrate biometrics with other door access systems to increase security especially in restricted areas. This decreases the likelihood of bypassing areas by taking advantage of the weakness of a single system. Security personnel can easily respond to emergencies and security breaches through instant communication with the use of SIP intercom and the IP CCTV if the office also uses VoIP.

Types of Biometrics
Biometrics used to monitor office are primarily divided into two major categories:

• Physiological biometrics measures and analyzes physical features such as the face, iris or retina, hand, fingerprint, finger vein, and DNA.
• Behavioral biometrics measures and analyzes the voice, signature, and keystroke of a person.

Fingerprint
The fingerprint or thumbprint biometric is used by taking an image of the features such as the loops, arches, outline, furrows, and whorls. The records are then stored to serve as a basis for the matching and verification next time someone wants to gain access. Thumbprint biometric uses three methods to match the features; ridge feature examines the ridges, correlation overlays the record image and the scanned image, and minutiae matches the set of points. If there is an issue during the verification, security personnel can double check through the CCTV camera placed near the area.

Face Recognition
Facial biometric is the use of patterns and nodal points on the face to verify a person’s identity. Sometimes the image from an analog camera isn’t reliable, but a comparison of at least 80 points on the face is not easy to bypass. These points measure the facial biometric of the eye socket depth, nose width and length, and the shape of the cheekbones. An IP camera within the vicinity can double-check the errors for easier coordination with the security.

Voice Recognition
Voice recognition utilizes both the physiological and behavioral features in analyzing and comparing speech patterns. The system will compare the frequency, nasal tone, inflection, and cadence of the person’s voice with the stored data as a form of authentication. If there is an issue, installing an analog camera within the vicinity will make monitoring easier.

Iris Recognition
This type of biometric door access feature records and analyzes the patterns in the ring around the pupil of the eye. Like fingerprints, the patterns can be difficult to recreate and fake. Some offices that require a high-level security utilize this along with the intercom system and a reliable CCTV camera to restrict entry to specific areas in the building in place of a security camera.
