Is your legacy analog video security system reaching the end of its life? Some companies have been hesitant to make the leap to IP-based video, while other companies continue to look for the most cost-effective solutions to utilize existing infrastructures and maximize their surveillance investment while also adding new IP cameras. Meanwhile, the benefits of switching analog cameras and aging DVR systems to IP-based surveillance systems and network video recorders (NVRs) continue to grow.
Leverage Existing Infrastructure and Add IP Technology
Video surveillance technology is rapidly improving. Hybrid NVRs allow users to connect existing analog cameras and encoders as well as the latest IP cameras to the same server. This approach maximizes a company’s initial security investment while providing the flexibility to upgrade over time. As a result, end users can add IP cameras to their system in order to reap the benefits of high definition resolution, panoramic video, camera-based video analytics and more.
So What Makes IP Video Better?

IP-based video provides radical improvements over analog video. IP video is transferred over a computer network cable instead of a coaxial cable, which provides options for more flexible and higher resolution video. IP video improvements include video resolution, event analytics and situational awareness.
- Larger, flexible viewing areas – Standard definition analog cameras have a maximum resolution of 704 pixels wide by 576 pixels tall—or .4 megapixels of resolution. Most IP cameras are between 1-5 megapixels, and some are up to 20 megapixels. In many cases, one IP camera can cover the same area as four or more analog cameras. Flexible resolutions are available to optimize the viewing area of the user’s environment. IP cameras can define their own aspect ratios to meet specific needs.
- Panoramic video – There are many IP cameras on the market today that use multiple lenses and imagers to create 180 to 360 degree fields of view. Other cameras utilize panoramic or “fisheye” lenses to achieve these parameters on a single lens. A good VMS will allow you to bring this powerful video into your server with a single stream and to even zoom in and move around within the image for greater detail.
- Improved camera analytics – Many IP cameras make use of video analytics that are built into the software or firmware utilized by the camera. These “smart” cameras can detect when a person or object crosses a line, detect objects left behind or removed from a field of view and more. These events are sent from the camera to the server so the user can be quickly notified. This approach does not require as much processing power from the server while freeing it up for other video management system tasks
- Manage video from anywhere – IP-based video gives users the opportunity to easily view live and recorded video from any location through a PC, web browser or mobile device.
How to Configure Your System with Analog and IP
You know the cameras your company has in place or want to add to your system and need to know what server best suits your needs. An online configuration tool can help you calculate the approximate storage and bandwidth necessary for a security system. Users can simply enter the number of analog and IP cameras, the number of streams, compression, desired video resolutions and other features to find the best NVR that fits their needs.
