Chap.1 IP Surveillance Overview

1.1 Overview

Increasing penetration of the Internet and the development of innovative technologies have encouraged rapid

growth of the IP surveillance industry, driving changes in the video surveillance market. It is expected that IP

surveillance will be dominating the video surveillance market in the near future, with network cameras and video

servers being major trends.

An IP surveillance digitizes video streams and transmits them over networks, allowing users to view and manage

the video and images remotely with a networked device, such as a PC, anytime and anywhere. Key components

of an IP surveillance system consist of network cameras, video servers, network video recorders and central

management software. VIVOTEK provides a full range of products mentioned above to help customers build a

reliable and high performance IP surveillance system that meets their needs.

IPsurveillanceproductsarebeingusedinavarietyofapplicationelds,whichgenerallyfallintothefollowingfour

categories:

●Professional applications: transportation, government, industrial, construction, health care, etc.

●SMB applications: banking, education, retailing, recreation, etc.

●Home applications: residential surveillance, digital home, etc.

●3GPP applications: mobile surveillance, elder care, baby or pet viewing, etc.

1.2 Network Cameras

1.2.1 Introduction

A network camera, also known as Internet camera, IP camera or Internet video camera, transmits live digital video

over an Ethernet network to back-end devices such as a PC or 3G phone. With a dedicated IP address, a built-in

web server and audio/video streaming protocols, it can work independently for real-time monitoring.

Images from network cameras can be viewed with a web browser such as Internet Explore, Firefox, Mozilla and

Opera, enabling customers to perform live viewing on different networked devices. In addition, customers can

control and manage multiple cameras at the same time in any places where network connection is available.

Therefore, an IP surveillance system is easier and more convenient to use compared with a CCTV system.

IP Surveillance Overview

Chap.1

Chap.1 IP Surveillance Overview

A network camera mainly consists of a lens, an image sensor, an image processor, a video compression SoC

(System on Chip) and an Ethernet chip that offers network connectivity for data transmission (Figure 1.2).

When light passes through the lens to the sensor, it is converted to digital signals and then processed by a built-in

digital signal processor. The processed video data is then compressed by a multimedia SoC to achieve a smaller

data size for optimal transmission. Finally, the video images are sent through the Internet to back-end devices to

allow for viewing and storage. Apart from video compression, the SoC is built with a RISC CPU for processing

system and network data.

The general interface of a network camera includes a power cord socket, an Ethernet socket, audio I/O ports and

digital I/O ports (Figure 1.3).

Chap.1 IP Surveillance Overview

In addition to a full-range IP surveillance product lineup, VIVOTEK has achieved competitive advantages over

other rivals in terms of multimedia SoC design, EE & ME integration and multimedia SDK. With these capabilities,

VIVOTEK is able to provide highly integrated products with superior image quality, comprehensive customer

services and versatile application solutions.

1.2.2 Camera Types

Generally,networkcamerascanbedividedintofourtypesfordifferentapplications,includingxed,pan/tilt/zoom,

xeddomeandspeeddome.

Fixed Type

A fixed network camera points in a fixed direction to monitor a specific area, such as hallways, staircases or

corridors. Because people can be aware of the camera’s shooting direction, in some cases, it can deter vandalism

and crimes.

AxednetworkcamerausuallycomeswithaRS-232/422/485interfacethatconnectsthecamerastoapan/tilt

scanner for wider coverage.

Manyxednetworkcameras has exchangeable C/CS-mountlensdesign,givinguserstheability to change the

lens to adapt for different monitoring conditions. For more information on C/CS-mount, please refer to Chapter 2.

Figure 1.4 Fixed network camera

Figure 1.5 PTZ network camera

Pan/Tilt/Zoom Type

Capableofchangingshootingdirectionhorizontallyandverticallytoachieveawideeldofview,apan/tiltnetwork

camera is used in many spacious areas, such as lobbies or parking lots.

Some pan/tilt network cameras are integrated with zoom capability so as to provide close-up images of distant

objects. Users can easily control PTZ functions through a web browser.

Chap.1 IP Surveillance Overview

Figure 1.8 Video server

1.3 Video Servers

A video server is a device that converts analog signals to digital, allowing users to migrate to a digital surveillance

system without replacing existing CCTV systems.

A video server mainly includes a compression chip and an Ethernet chip, with two main types available: one port or

four ports.

Speed Dome Type

Comparedwithxeddometype,aspeeddomenetworkcameraisintegratedwithpan,tiltandzoomcapabilities,

enablingafargreatereldofview.Withahighzoomcapability,imagestabilizationand360-degreeendlesspan,a

speed dome camera is mainly used for professional applications, such as airports, banks or city security.

Fixed Dome Type

A fixed dome network camera, mostly designed for indoor surveillance, has a housing to make the object of

interest less aware of where the camera is pointing at. With a 3-axis mechanism, images can remain in an upright

orientationwhenitisinstalledeitheragainstthewallorontheceiling.Furthermore,thedesignofaxeddome

networkcameracanbettertinwiththe decor.

Axeddomenetworkcameracanbefurnishedwithaweather-orvandal-proofhousingforoutdoorapplications.

Chap.1 IP Surveillance Overview

1.5 Central Management Software

Central management software, often provided by the camera vendors or individual software vendors, enables

customers to manage and control cameras from remote site. Typically, central management software is windows-

based, and thus can be installed in almost any PC.

Central management software employs client-server architecture where server software,client viewing software

and playback software is installed in separate PCs. Customers can perform live viewing, event-triggered recording

or playback on the client PC while managing cameras and performing constant recording with the server PC. Each

server PC can be scaled up to include several subordinate server PCs, and thus expand the number of managed

cameras.

VIVOTEK ST7501 central management software works seamlessly with VIVOTEK’s full-range network cameras

and video servers, helping customers establish a robust, flexible and efficient platform for centralized video

management.

Figure 1.10 Central management software

1.4 Network Video Recorders

An NVR (Network Video Recorder) is an IP-based recorder that operates independently from a PC or other

operation systems. Aimed to store digital video streams from network cameras, an NVR is usually incorporated

with a large-volume hard disk to allow for a long period of recording.

An NVR differs from a traditional DVR in its network connectivity, which allows digital data to be transmitted to other

networked devices over the Internet. Another difference is that an NVR can be directly connected to a network

camera while a DVR is usually be connected to an analog camera.

VIVOTEK’sNR7401helpsyoubuildahigh-efciencysurveillancesystem,whereyoucansimultaneouslyrecord,

monitor and manage video data through the Internet. NR7401 works seamlessly with all VIVOTEK network

cameras.
