Introduction

The transition to an IP-based CCTV system is being fueled by several needs. The growing trend for organizations to centralize their operations means that cameras are getting further and further away from the center of operations. Only LANs and WANs can cover these distances economically. What’s more, in new constructions, it is estimated that between 50 to 60% of costs can be saved by laying down twisted-pair LAN (CAT-5) cables compared to analogue systems. It is simpler and more economical than laying thick bundles of coax, fiber, audio wires, PTZ control wires, alarm input wires, relay output wires and power cables. And, when combined with Power over Ethernet, the savings can be even greater.

Here are some other important reasons for choosing
IP Video:

Scalability and flexibility. Unlike analog CCTV systems, cameras can be added in increments of one up to hundreds, or even thousands. What’s more, frame rates and storage can be increased at any time and at any place in the network, simply by adding more hard drives and servers.

Camera functionality. CCTV over IP allows ‘intelligent’ functionality to be embedded within the camera – including motion detection, Intelligent Video Analysis, sensor input, relay output and alarm triggering. Dedicated IP cameras with progressive imaging and megapixel resolution also overcome the limitations of PAL/NTSC.

Cost-effective infrastructure. Existing twisted-pair LAN or Internet cabling can be used. Even if installing a new infrastructure, twisted-pair cabling is much less expensive than coax.

Open standards. Global standards as used in IT infrastructures allow cost savings through use of open system components and interoperability with other networks, including compression and wireless connectivity technologies.

Network functionality provides optimal accessibility and cost saving. One network can transmit video, audio and data with remote and shared availability through both wired and wireless connections. In addition to multiple video signals, commands for PTZ (pan, tilt, zoom) cameras can be transmitted via the same cabling.

Easy integration with other security systems. Video surveillance can also be integrated with other systems and functions such as access control, alarm systems, building management and traffic management.

Future-proof installations. Users remain up-to-date with the latest developments thanks to field-upgradeable products allowing firmware to be updated over the network.

Reliability. Maximum reliability is assured through a redundant infrastructure and management software that provides real-time health status of the entire network and preventive maintenance.

Accessibility. Real-time or recorded images can be accessed from any location where network or internet access is available, providing further convenience and cost savings.
