types of security countermeasures

There are three types of Security Countermeasures: Hi-Tech, Lo-Tech, and No-Tech. These three must be used in combination to create a layered and effective security program. No single security countermeasure is effective against all threat scenarios. Access Control Systems, in particular, are a type of “controlled vulnerability” as each access control portal is a hole …

Access Control System Planning

Designing an access control system can be a daunting task, especially if the system required is substantially larger than what is already in place. But if you approach it methodically, you can reduce error and ensure that you get the exact system needed for your facility. Assess the Situation Observe Your Environment Conduct a Site …

hand geometry recognition

Hand geometry recognition systems are commonly available in two forms: full hand geometry systems that measure the entire hand, and finger geometry systems that measure only the index and middle fingers. Hand and finger geometry biometrics are automated measurements of hand and finger dimensions taken from a three dimensional image. A reader or camera captures …

fingerprint recognition

Fingerprint recognition is one of the most widely used biometrics in the access control industry.This is because fingerprints are one of the oldest forms of personal identification, inexpensive to collect and analyze, and they are stable. Biometric fingerprint access control applications use one or both of two fingerprint characteristics: ridge patterns and minutiae details, which …

facial recognition technology

Facial recognition is a biometric access control technology that uses one or more photographic images to recognize a person by measuring points on a face under controlled conditions. Facial recognition systems are not intrusive, require no physical contact with the user, and have a high rate of user acceptance.Facial recognition is not affected by race …

contactless smart card

Some access control systems use smart cards that, in addition to having processing or memory capabilities, have a radio frequency (RF) communications capability that allows a card reader to interact with them at a short distance. These are referred to as contactless smart cards.Contactless smart card systems can be used in high-security applications that may …

contact smart card

Access control systems using the contact smart card can be employed in high-security applications which involve large numbers of people that require significant flexibility and layering, but need only moderate throughput rates. These systems are replacing many of the key card and magnetic stripe systems due to their ease of use, security, and reliability. Homeland …

Magnetic Stripe Cards

Magnetic stripe cards are tokens used for authentication and access control in many security environments. Magnetic stripe card readers can be interfaced with a variety of access control equipment, including locally controlled electrical locks, or centrally controlled security databases. Magnetic stripe cards are identical in composition and appearance to bank or credit cards. The stripe …

door position monitoring

Door position monitoring devices provide status of a door (door is ope n or closed) to the access control system, allowing it to engage locks, annunciate alarm conditions, and other actions that provide security. For example, an authorized user ma y access a door and pr op it op en, allowing the unauthorizedd entry of …

access control Barriers

access control Barriers devices control vehicular access to specified areas while providing various levels of security to the facility. Barriers generally protect and control vehicular entry points by allowing only authorized vehicles. Many styles of barriers are available, such as wedge or drop arm barriers as well as ornate gates and planters. Retractable or removable …
