Fast & Easy Deployment of a Cost-Efficient Infrastructure
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 to include video functionality. IP-Surveillance solutions utilize a normal IP-based network for transmitting and distributing video, thus eliminating the need for costly, time-consuming dedicated cable installation. Under these circumstances setting up a network video system is both simple and cost-effective.
The only action required is to set the IP addresses of the network video products. Once the basic system is up and running, it can be fine-tuned in a number of ways: by adding other functions such as motion detection, alarm handling, time stamping, local programmability, digital inputs and relay outputs, and Pan-Tilt-Zoom control – all communication running over the IP network, there is no need for additional cabling.
The Network Camera
A Network IP Camera is a self-contained camera and processor. The user can use a standard web browser to view live, full motion video from anywhere on a computer network, including over the Internet. This is a more economical alternative for many businesses and organizations than high-priced Closed Circuit TV (CCTV) systems. Installation is simplified by using existing LAN wiring and/or wireless LAN. This eliminates the expense of installing additional cabling. Features such as motion sensing with e-mail notification, simultaneous user login, and FTP upload capability further differentiate the device from current video technology.
Analog VS Digital Surveillance Systems
With a CCTV analog surveillance camera, the analog video signal is sent through a coaxial cable to a video recorder or monitor. One cable can transport only one video signal from one camera at a time. If you have two cameras, you need two cables. With an IP-based network camera, the network camera immediately digitizes the images and the video stream is ready to be sent over any computer network available. One network cable can easily handle signals from two network cameras simultaneously. In fact, one standard UTP network cable can forward images from more than 220 network cameras simultaneously, without becoming overloaded.
Bridging the Technological Gap
IP-Surveillance technology offers more cost-efficient, future-proof solutions that bridge the technological gap between the analog and digital worlds. Video servers, for example, can be integrated into an analog CCTV system to digitize analog video sources and distribute digital video over an IP network — essentially turning analog cameras into network cameras.
A major advantage of using a video server in an analog system is the ability to access real-time video remotely, via an IP network. Live video can be accessed by authorized personnel at any defined workstation on the network, or over the Internet. Additionally, video servers can, using built-in serial ports, control equipment such as Pan/Tilt/Zoom cameras, or special cameras such as super sensitive black/white cameras, miniature cameras and microscope cameras. Furthermore, inputs, such as alarm events, can be used to trigger the server to start transmitting images. Servers equipped with image buffers can also send pre-alarm images.
Camera video server solutions are ideal for sharing high-quality video streams over existing computer networks. Superior to analog video solutions, IP-Surveillance means reliable and distributed access or recording of high-quality digital images, and improved functionality and cost.
