Benefits of A Network Security Camera System

By Marc Ramsey

There are many benefits to installing a network based security camera system over more the more traditional analog security systems. For starters, remote accessibility provides an accessibility convenience. Higher image quality, flexible video management, easy integration possibilities, more scalability, and cost effectiveness are all advantages that analog security camera systems just cannot provide.

Someone could access, manage, and view live and recorded video from anywhere around the world with an internet connection. Network security systems these days are also referred to as IP-based networks because the communicate over the network using the Internet Protocol, which is the same thing as your office network that you can connect to from virtually anywhere, anytime through the internet.

This allows for a third-party company, such as a security firm, to provide additional services such as diagnosing problems or monitoring the system.

Monitoring an analog security system is restricted to wherever the station is set up. There is one central location that the monitoring, viewing, and managing of video take place. An analog system can be upgraded to take advantage of network capabilities by installing additional equipment. It would require a video encoder to convert analog video into digital to be recorded on a digital video recorder, which is a digital version of a cassette tape used in analog systems.

In terms of video quality, network security cameras can offer high resolution images and digital enhancing technology that analog cameras cannot. Over time, stored analog tapes degrade while digital data do not so the video will always remain in the quality that it was recorded.

With analog systems that uses DVR, there has to be conversions from analog to digital in the camera, then converted back to analog to transport through the analog cables, then again to digital to be recorded. With each conversion the image quality is degraded. Analog video signals also become weaker the more cabling it has to travel through. In a fully digital system, images are digitized once in the network camera and stay digital so there is minimal degradation.

Possibly the best advantage of a network system is being able to add and remove a network camera from anywhere within the network. As long as there can be a connection to the network, be it through a network cable or wireless signal, there can be a camera. This removes the costly cabling of the analog system in which each security camera requires its own cable direct to the central station.

As a video security system grows and cameras are added or removed, the internal infrastructure very flexible to accommodate the systems needs. It helps that all network security products are built to a standard so any of the products can easily be integrated into the system.

It's much more cost effective to have a network security camera system especially if it's a brand new system. The management of an analog system is a dinosaur's headache. With advancing techonolgy analog products are slowly fading into the backdrop as network cables and wireless devices are becoming cheaper to produce and increasing in popularity.
