Be Mindful of Monitor Choices
Obviously, the most important attribute is picture quality. Professional monitors provide advanced picture quality with SXGA (super extended graphics array) resolution greater than 1,000:1 contrast ratio, maximum of 5ms response time and minimum of 300 cd/m² brightness. They also feature a built-in durable power supply that provides continuous 24-hour operation as well as tempered glass, which protects the delicate LCD panels for long-life viewing.
Help your customers select a monitor that meets their current and future requirements. For instance many monitors have limited feature sets and lack the versatility to connect to the video devices in a system. Multiple video formats, such as composite, YC, VGA and looping outputs may be missing from a lower cost monitor.
Professional monitors incorporate a built-in de-interlacing function, which insists on a 3-D comb filter. The comb filter is designed to help correct detail and color loss that occurs when the video display renders the signal onto the screen by layering several versions of the image on top of one another. The comb filter is effective when displaying analog signals on the monitor.
Beating the Bandwidth Blues
One key advantage of IP-based video is the ability to use network infrastructure, providing adequate bandwidth and availability of switching and routing, rather than coaxial cabling. However, running bandwidth-intensive surveillance video over corporate data networks is a point of organizational contention, depending on the potential impact on network performance. If there is not enough bandwidth in the network to handle the high resolution network cameras, the results will be less than satisfactory.
Realizing the prospective growth of IP video, a group of video management companies are now creating software to help manage the capture and storage of video content. Likewise, video surveillance hardware manufacturers are working with them to assure that the transportation of IP images will yield clean, usable video. When migrating to IP video surveillance, the integrator will want to make certain the video hardware provides an agnostic software interface so the desired software can be used without compromise.
IP Holds the Key to Your Future
To be successful in the future, you will need to be able to deploy IP/digital video solutions. Indeed, there are specific markets — education, law enforcement, transportation, water treatment and new construction — that will now only specify IP/digital video solutions. Manufacturers are every bit as interested in selling IP/digital video to these markets as you are, so put them to work for you.
