The Four Main Types of Security

Surveillance camera distributors help to provide security integrators with key resources, such as wholesale security cameras and technical support. As invaluable as reliable surveillance camera distributors might be, they are only one small part of a well-executed business security strategy. 

Across most commercial applications, there are generally four main types of security. These four types of security include physical security, access control, surveillance camera systems, and intrusion alarms. 

Together, these four areas make up the vast majority of the security surveillance industry. Understanding the importance of each of these individual areas of security and how they can benefit your business will allow you to enhance your overall security plan with a fully integrated, modern strategy.

Continue reading the article below to examine the four different types of security in more detail. If you’re interested in speaking with established wholesale surveillance camera distributors about your security product and service needs, contact eLine Technology to learn how we can help.

The Four Main Types of Security

#1. Physical Security

The first and most common type of security is physical security. Physical security begins with the most basic forms of security, such as the doors and mechanical locks that prevent people from going anywhere or entering secure areas. 

There are a diverse variety of doors designed for both interior and exterior applications. Depending on the purpose and setting, a well-constructed door is the first step to ensuring solid security practices. 

In order for doors to remain closed and secure, there has to be some type of lock. Keys locks and basic mechanical push button locks are the most common types of security locks still being used around the world. 

These traditional locks are inexpensive and, depending on the quality of the lock, can provide a sufficient level of safety and security. Using superior security locks that have added security features, such as restricted keys and reinforced strikes, is recommended for those that prefer to increase their level of physical security.

#2. Access Control

The second type of security is access control. Access control can either be a simple, single point of access or include thousands of entry points. Access control systems electronically restrict people from entering secured areas. 

The most basic types of access control systems are keypads that require users to enter PIN access codes for entry. However, the most common type of access control system now is what is known as proximity card access control systems. 

A proximity card is a standard sized access card that transmits a secure code when held up to the reader. The transmitted code is then determined by the access control security system whether access is granted or not. 

Another type of physical object access control technology is smart cards. Smart cards are similar to proximity cards. However, smart cards contain a much larger amount of information, which can easily be modified using the interface of the access control security system the card is associated with. 

Smart card technology has begun to increase in popularity in recent years mainly due to their popularity in government facilities. Government buildings generally utilize a type of smart card known as a Common Access Card or CAC. 

The most advanced form of access control is biometrics. Biometric access control systems utilize human characteristics, such as a fingerprint, handprint, or facial recognition, to determine who a person is and what access rights they are granted in the system. 

However, biometric technology is fairly expensive compared to proximity entry systems. Still, the increasing technological advancements and availability of biometrics make it a popular choice for integrated systems in areas that require a higher level of security.

#3. Surveillance Camera Systems

The third type of security is video surveillance. Video surveillance systems utilize security cameras placed at strategic points to capture video for live monitoring and playback recordings of footage. Thanks to the growing number of surveillance camera distributors and security integrators around the world, video surveillance solutions have never been more affordable and accessible.

There are many technologies used in modern security camera systems, including analog CCTV, which are cameras that use coaxial cables, and network IP cameras, which use Ethernet cables. Recording on standard videotapes is now no longer common and has instead been replaced by digital video recorders (DVRs), network video recorders (NVRs), and cloud storage systems. 

Generally speaking, a DVR is part of an analog CCTV camera system while an NVR uses network IP cameras. Many modern video surveillance systems now actually take advantage of both technologies, known as a hybrid surveillance system. Hybrid security camera systems allow users to utilize both older security devices while still being able to take advantage of the latest advancements.

#4. Intrusion Alarms

The fourth type of security is intrusion alarms, also known as burglary systems. Intrusion alarm systems are commonly found in both residential and commercial security applications around the world.

Alarm systems can be relatively inexpensive, depending on their size and level of functionality, and provide a sufficient level of security. To detect an intruder, intrusion alarm systems utilize various detection devices, such as motion sensors, door contacts, glass break sensors, and input switches like panic buttons. 

The signals from detection devices are transmitted to a central control panel which then communicates to a central monitoring station. The central monitoring station is a location that receives the alarm signals from the control panel and then contacts the appropriate emergency services (police, fire, medical) in order to quickly dispatch them to the location of the alarm.

These four areas of security make up the vast majority of the security surveillance industry. Together, these types of security systems are utilized in homes, businesses, commercial properties, and institutions to protect people, property, and valuable assets.
