Advantages to Network Security Systems Over Analog Systems

The benefits of a network security camera system extend beyond the functionalities that an analog security camera system can provide. The advantages include remote accessibility, high image quality, even management and intelligent video capabilities, easy integration possibilities and better scalability, flexibility and cost-effectiveness.

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.

For this reason, third-party security firms began offering entire packages that will install and manage your surveillance system for you. They can securely and remotely access your cameras video feed without having to physically be on site. Most of the time they can even fix any problems that are diagnosed remotely.

With an analog CCTV system, you would have to be at the monitoring site to view and manage video, and remote video access would require installation of additional equipment such as a video encoder or a network digital video recorder (DVR). A DVR is the digital version of a video cassette recorder.

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.

In an analog system, each camera needs a cable running directly from the security camera to the monitoring station. Network cameras can be placed and networked or removed from virtually anywhere.

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.

For this reason, once the network system is already in place, it is much more cost effective than an analog system on the basis of the flexibility alone. Network cables and wireless devices are also cheaper than traditional cabling for analog systems.
