Real-Time SurveillanceWatch (RTSW) provides real-time surveillance of multiple remote sites on an interactive web site. Digital cameras capture high-resolution images which are displayed on web pages allowing World Wide Web clients to view these sites. The design of the RTSW makes use of the latest Internet technologies.

Features

The RTSW features are :

Capture, display and storage of high-resolution images
Displaying video in real-time (video streaming)
Selection, configuration and display of multiple cameras
Display of local and/or remote cameras over LANs, WANs, PSTN and Internet
Use of commercial image compression standards
Centralised or distributed control centres
Control of zoom, focus, pan and tilt of remote cameras from local or remote control centers
UPS (Uninterruptable Power Supply) provides orderly shutdown and start-up in the event of a power failure

Optional features of the RTSW :

Image processing of captured images for surveillance purposes, for example feature extraction
Delta frame motion detection

Applications

Monitoring or surveillance of remote sites
Security systems

Operation

Custom software executing at local or remote stations extract data and images from the local or remote stations and generate data which is then transmitted via modem on leased or dial-up line to the RTSW Server. Local operators and/or remote WWW clients may then view the data and images.

Architecture

The RTSW consists of the following components :

Data Interface (for local sensors other than cameras)
Digital Camera
Camera Controller with Pan/Tilt (optional)
Uninterruptable Power Supply (UPS)
Remote Surveillance Station with modem
Dial-up or leased line connectivity to the RTSW Server via the Public Switched Telephone Network (PSTN)
Leased line or dial-up connection via an Internet Service Provider (ISP) to Web Clients
