Meeting today’s video surveillance challenges.
The video surveillance market is booming, driven by increased public and private security concerns, as well as a technology shift. The transition to network video is a reality as customers take advantage of flexible, industry standard systems for security and video surveillance. As security management over the IP network expands and intelligence capabilities move out to network cameras, systems can scale much more easily. This move to open systems empowers a much more productive and cost-effective means of surveillance than was ever possible. For the security manager, the shift to network video creates new opportunities where digital technology can be put to use to deliver maximum value.
A network video system is able to send video without the need for a dedicated physical infrastructure. It uses standard IP networks, such as Local Area Networks (LANs) and the Internet, for transporting information, rather than dedicated point-to-point cabling, such as that used in analog video systems.

Significant investments in analog CCTV systems may have already been made. The technology shift to network video does not, however, mean that existing analog CCTV investments have to be discarded. With a network video solution, you can integrate your existing analog system into an IP-based solution.
IP video surveillance systems provide tremendous benefits including exceptional image quality and advanced functionalities. Due to these benefits, migration to IP system is only a question of time. We can help you with the perfect video surveillance solution for your business no matter where your analog system is.
IP surveillance offers several advantages over traditional CCTV analog video technology. Take a closer look at the many ways in which network cameras have surpassed their analog counterparts.
Superior image quality enables the user to more closely follow details and changes in images, making for better and faster decisions to more effectively safeguard people and property.
A network video system can be scaled at any time to meet your growing needs. New technologies, additional cameras, and extra storage capacity can all be easily added as required.
There are almost no limitations as to where a network video product can be placed. Network video has the capacity to provide a high level of integration with other equipment and functions .
Now with onboard intelligence, the IP camera can detect motion and audio, manage alarms such as active tampering - and decide when to alert or send a video to a certain operator.
The majority of businesses now have high-speed, IP-based networks connected to the Internet. Adding a network video system simply utilizes and extends the same infrastructure.
More ways to secure access, passwords can be used to limit access, and video can be encrypted before being sent over the network to make sure it cannot be viewed or tampered with.
Network video products provide an easy way to capture and distribute high quality video over any kind of IP network or the Internet. The video can also be stored at remote locations.
Based on open standards, IP video products run on IP networks. Using standard PC server hardware rather than proprietary equipment such as DVRs radically reduces equipment costs.
Progressive scan: Depicting moving objects clearly
Many network cameras employ progressive scan technology that better depicts moving objects clearly. This advanced image capture technology means that the whole image is captured at one time, thus providing crystal clear images even with a high degree of motion.
Power over Ethernet: Increasing savings and reliability
Not available for analog cameras, Power over Ethernet (PoE, IEEE 802.3af standard) means that the cameras get power from a PoE-enabled switch or midspan over the same standard cable that transmits video. PoE provides multiple benefits, including reduced installation costs and flexibility in camera placement. In addition, cameras can get centralized backup power from the server room, so in the event of a power failure they will continue to operate.
HDTV and megapixel resolution: See what you’ve been missing
A megapixel network camera provides more detail or can cover larger areas. In addition to the advantage of depicting more detail with greater pixel density, it can be used to digitally pan, tilt and zoom, and to create multi-view video. An HDTV network camera provides even better video quality with full frame rate and excellent color representation.
Wireless networking: For full installation flexibility
Sometimes wireless solutions are the best and most costeffective option for video surveillance installations. For example, it is useful in historic buildings, where the installation of cables would damage the interior, or within facilities where there is a need to move cameras to new locations on a regular basis. The technology can also be used to bridge sites without expensive ground cabling.
According to independent research on the differences between analog and digital solutions, installation, configuration and training costs for analog systems are almost 50% more than for IP systems. For example, cabling is almost three times as expensive in analog systems compared with IP-based systems. The primary reason is that coaxial cabling is more expensive than Ethernet cabling.
Also, analog typically requires separate power cabling, while Power over Ethernet eliminates the need for electrical connections in the IP system, and separate cabling is also needed to control analog PTZ cameras. A network video system allows users to incorporate open PC systems and open storage with video management software, which costs 20% less than DVRs.
If an IP infrastructure is installed, the network video system is always lower in cost. Network video systems of 40 cameras or more have a lower total cost of ownership than analog-based systems.
32 cameras is the break-even point for IP systems vs. analog. Beyond 32 cameras, the network video system in common scenarios has a lower cost, and between 16 and 32, the cost is quite similar or may be slightly lower for analog systems.
Network video products have other benefits that cannot be quantified: scalability, easier integration with other systems, superior image quality, better maintenance and service, easier troubleshooting, and many more.
