IP Cameras

Setting up IP Cameras for security or Web Cameras for Video Conferencing Support

An Internet protocol camera, or IP camera, is a type of digital video camera that unlike analog closed circuit television (CCTV) cameras can send and receive data via a computer network and the Internet. Although most cameras that do this are webcams, the term "IP camera" or "netcam" is usually applied only to those used for surveillance.

Types of IP Cameras - There are two types of IP cameras that are used.

Centralized IP cameras - which require a central Network Video Recorder (NVR) to handle the recording, video and alarm management.

Decentralized IP cameras - which do not require a central Network Video Recorder (NVR), as the cameras have recording functionality built-in and can thus record directly to digital storage media, such as flash drives, hard disk drives or network attached storage.

A Webcam is a video camera that feeds its images in real time to a computer or computer network. Unlike an IP camera (which uses a direct connection using ethernet or Wi-Fi), a webcam is generally connected by a USB cable, FireWire cable, or similar cable. Their most popular use is the establishment of video links, permitting computers to act as videophones or videoconference stations.

Uses of IP Video Cameras

Childcare webcast video monitoring - Childcare webcams can offer improved security, communication, and increased service value in daycare facilities.

Commerce - The webcam act as a 'magic mirror' to allow an online shopper to view a virtual item on themselves. The Webcam Social Shopper is one example of software that utilizes the webcam in this manner.

Video Calling and Video Conferencing - As webcam capabilities have been added to instant messaging, text chat services such as AOL Instant Messenger, and VoIP services such as Skype, one-to-one live video communication over the Internet has now reached millions of mainstream PC users worldwide.

Video Security - Webcams are also used as security cameras. Software is available to allow PC-connected cameras to watch for movement and sound, recording both when they are detected. These recordings can then be saved to the computer, e-mailed, reviewed over smartphone, or uploaded to the Internet.

Video Clips and Stills - Webcams can be used to take video clips and still pictures.

Input Control Devices - Special software can use the video stream from a webcam to assist or enhance a user's control of applications and games. Video features, including faces, shapes, models and colors can be observed and tracked to produce a corresponding form of control.
