How Access Control Systems Work?

Access Control Systems enable an individual or group to control access to certain areas within a facility or computer information system. In physical security there are several components related to this type of system that I will be covering in this article.

Control Points

Access control points can be a door, turnstile, elevator, parking gate, or any other barrier where access can be granted or denied. Most access points are doors and these points can be controlled by electric locks. Rather than requiring a human operator to control the locks, an electronic reader is used to determine the level of accessability that is to be granted to incoming traffic.

Types of Readers

There are many different kinds of readers that are used to control entry points. Readers can use biometrics to scan finger or hand prints, they can be keypads that require a key code, and they can also be used to read keycards. Advances in network technology over the past decade have led to the increased use of IP readers. These readers are often PoE enabled which allow them to be easily integrated with battery backups. This means that in the event of a power failure, the control system will still operate properly. Control readers do not usually make the decision, but instead pass the information along to a control panel that verifies the proper access level.

Cost and Benefit

Access control systems are extremely affordable these days and can easily be installed into any size facility. In addition to affordability, the benefits of having a control system far out-weight the cost incurred.

Top 3 benefits of using Access Control Systems:

  1. Authorization – granting only authorized users entry to doors or systems
  2. Accountability – logs and records that can account for an individual’s actions
  3. Identification – verifying an individual’s identify and level of accessability

Video conferencing has become an essential component of the business world, but there are some schools using this technology for educational purposes as well. You may not think of school teachers reaching outside of the classroom for learning experiences with their children, but this is exactly what is happening in the modern classrooms around the world.

Bringing the World to the Classroom

It used to be that children learned about the culture and current events of other countries by reading outdated text books, looking at pictures, or hearing what their teachers had to say about the country. They learned about current events and different cultures without having a personal or deep connection with those people.

Today, this is changing because teachers are learning how to bring the outside world into the classroom in a very real way. Instead of just reading old textbooks and maybe reading newspaper cut outs, students are able to use video conferencing to talk with real people who may be in different states or even different countries. They are able to see and hear others in a way they could never see and hear a textbook.

Many schools can set up one area of the school for video conferencing and use it as a shared area for all classrooms. They can have conferences for grade levels or large conferences with the entire school. School districts can even bring together groups from many different schools and allow them to attend the same conference with a special speaker all at the same time.

This is the ideal solution to many problems within modern schools. Students are now supplementing textbook education with video conferences.

Video conference equipment is being utilized by more businesses today than ever. The growth of this technology is expected to rise significantly over the next few years. Much progress has been made in just the past couple of years in the video conferencing industry. It makes communicating all over the world faster and easier. There are many applications and benefits for utilizing this futuristic technology, many of which are being used today.

Distance Learning - Education institutions from high school to higher education use video conferencing for students. This provides a way for students to benefit from lectures without having to be in the classroom. Even if you live in another country, you can get an online education as long as you qualify and can pay for it.

Video conference systems include monitors, telepresence audio/visual devices and software respectively. Some software can be used via instant messenger video calls where others can be added when necessary. Larger systems provide large display HD monitors and high-quality voice solutions for big meetings in large corporations. No matter what there is a cost-effective solution for almost any business for video conferencing.
