IP Based Surveillance System

Modern technology makes it possible to connect cameras directly to the computer network in an office. Users can also place cameras in different locations outside the office and view images from the office. If there is a PC at home, images can also be viewed from the PC. Network cameras come with built-in computer processing systems and designated IP addresses.

For example, users can view images captured by any camera connected to the Intranet/Internet. Users can observe images captured by various cameras through any computer, and can also allow authorized users to browse images or publish live images on the website. These live images can enhance the appeal of the website, making it dynamic and attracting people to revisit the company website.

If a building has a good network infrastructure, it is very easy to add network cameras. This allows monitoring of personnel entering and exiting, or checking if there is a false alarm in residential areas.

Currently, most surveillance (CCTV) cameras are connected to a TV monitor. If a multiplexer is used, several camera feeds can be displayed on one monitor. In contrast, adding one or two monitors in a building is much easier than viewing images from other locations.

The most commonly used surveillance camera setup involves connecting analog cameras with a multiplexer to a monitor and recorder.

Connecting a complete set of equipment via the network. Users can view images captured by various cameras through any computer.

(All cameras in the image are network cameras.) Note: Users can also connect their home PC directly to a remote camera.

In what situations should users utilize network camera technology?

• If users want to add value to their website, they should allow visitors to see live images of the office, town, and hotel.
• When users want to view images captured by cameras while not present on-site.
• When users want to check what triggered an alarm. Many alarm systems can cause false alarms. If users have analog cameras, they can use a network video server to view needed images anytime, anywhere.
• When users already have a computer but do not want to purchase standalone equipment for the cameras. Users can use their computer's browser without needing to buy a separate TV monitor. They can also use existing computer network connection lines without needing to set up additional coaxial cables.
• When users are tired of replacing tapes in their recorders daily. Users can save images to the computer hard drive and let the computer automatically delete viewed images. The computer can delete images older than a month, freeing up hard drive space for new image data storage.
