Physical security is the protection of personnel, hardware, programs, networks, and data from physical circumstances. Physical security is often overlooked (and its importance underestimated) in favor of more technical and dramatic issues such as hacking, viruses, Trojans, and spyware. However, breaches of physical security can be carried out with little or no technical knowledge on the part of an attacker.

Security Cameras IP/Analog

If you are looking to install a security surveillance system in your home or business, one of the decisions you have to make is whether to go with an IP or analog camera. Deciding on IP versus analog cameras is not necessarily a simple decision as there are advantages and disadvantages to each style of camera. If you are looking to install a security surveillance system in your home or business, one of the decisions you have to make is whether to go with an IP or analog camera. Deciding on IP versus analog cameras is not necessarily a simple decision as there are advantages and disadvantages to each style of camera. We will explore some of these differences more in-depth so you can determine which option is right for you. The main difference between the two camera types is the way in which the video signal is delivered. Analog cameras turn the video signal into a format that can be received by a television or other receiver such as a VCR or monitor. An IP-based camera, also known as an IP network camera, digitizes the video signal using a specialized encoder that contains an onboard web server. This allows the IP camera to act as a network device, thus allowing captured video images to be viewed not only through an existing network but also through a web browser that can be accessed through the Internet.

Access Control Systems

Access control is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. An access control system, within the field of physical security, is generally seen as the second layer in the security of a physical structure.
