An access control system combined with a CCTV camera and intercom system can create better security features for any type of commercial building or residence in Singapore because they are deterrents to crime and can help with information-gathering. If you cannot choose between the conventional card and pin access or a biometric door access system, however, you should be familiar with the basics of biometric thumbprint and facial biometric, two of the most popular types used by establishments and offices.
The earliest types of door access systems used keypad readers and card readers, but personnel are prone to losing or forgetting their cards and passwords that is why the alternative biometric thumbprint is a better solution for improving security.
To capture a person’s unique fingerprint, the image is first scanned, converted into numerical algorithm, and then saved as a record in the database for authorized personnel or employees. What makes this type of biometric door access system invaluable is that the data cannot be faked easily and is less prone to errors. New personnel can easily be added to the secureoffice entrance card access machines database while those that are no longer affiliated to the company can simply be deleted. It can also be easily integrated into the CCTV camera system such as an IP CCTV through a secure network. The footage from the security camera can act as an additional proof in case the authorities are alerted of an attempt to bypass security. An office camera can also be installed near the fingerprint reader to monitor employee activities and attendance.
Facial biometric may be a stuff of science fiction movies, but it is widely used in some public areas that get heavy traffic daily. Unlike the other biometric door access system types, the facial recognition system does not require a person to place a body part in front of a scanner or reader to be identified. This is very useful in surveillance if the security does not want to alert the public or any suspicious person that they are being monitored through a security camera. This can be used in combination with several IP camera in government offices, airports, stadiums, and other public areas in Singapore.
The CCTV camera captures the measurements of the face through 80 nodal points such as a distance between several facial features. These include the length of the jaw line, the width of the nose, the distance between the eyes, the cheekbone shape, and the eye socket depths. The measurements result in a specific numerical code or a template which is then stored in the database. When the IP camera surveys a crowd, it compares the templates in its database to the captured samples in real time. If used as a confirmation of the identity of an employee for example, the person should stand at least two feet from the security camera and wait for a maximum of 5 seconds to determine if the sample matches the data. This less intrusive process in identification is what makes it an ideal alternative to other biometric door access systems used for public places in Singapore. Like biometric thumbprint, it can be very difficult to bypass, too.
