Anatomy of Video Surveillance Systems

By Fernando Severns Subscribe to RSS | April 17th 2012 | Views:

Continuously advancing technology improved almost everything, including surveillance camera systems that people can install in their homes and businesses. Security cameras these days are no longer as simple as they were years back. Their complex structure today is packed with numerous benefits like flexibility, accuracy, and efficiency.

Improvements on surveillance systems include sharper cameras and adjustable lenses that can capture clearer and better images. With these features, devices can now be set up even in remote locations – these devices then would not easily be reached or tampered with by other people. Accessibility to the Internet is a crucial player in today’s surveillance cameras since it allowed people to monitor their properties online. With that, captured videos and images can be transmitted and seen in real time.

To better appreciate the function of the current generation of security cameras, here is a detailed anatomy of the devices and the system as a whole. These components replaced the steady and black-and-white features that were used before. Today, hidden cameras can really be concealed and surveillance ones can be employed to watch over properties and prevent crimes.

Closed-circuit television (CCTV) systems are equipped with different cameras and multiple-channel liquid crystal display (LCD) televisions. Through these, an entire building of over 20 floors can be overseen effortlessly by just looking at a single monitor divided into several panes. All parts of the home including garages and backdoors can also be monitored as if with an eagle’s eye.

Another crucial development on video surveillance systems are high-tech camera lenses. These not only take footage from one direction, but also capture surrounding areas through pan, tilt, and rotation mechanisms. The improved magnifying capacities also allowed users to zoom on certain areas and move closer to particular objects and persons to see clearer images.

Most cameras of today’s video surveillance systems are also geared with motion sensors and customizable casings. The former can be used in easily reacting to detected movements possibly done by intruders. The latter, conversely, can be used for decorative and other functional purposes.

The development of wireless security systems also contributed a lot. As mentioned, these can connect surveillance devices to computers through the Internet; hence, people can watch the footages in real time and not wait for recorded videos anymore.
