Stand-alone network cameras from Wordsworth, the Pixord 100 and 120 incorporate all of the features required for secure, remote, real-time surveillance via the Internet.

The cameras remove the traditional requirement for a PC and the cumbersome process of installing software.

They connect directly to Ethernet and include a built-in video server with support for a variety of Internet protocols.

Up to 30 frames per second video content is viewable on the cameras, which use a Java-based web page for maximum platform compatibility.

Images from the built-in CCD camera are compressed using JPEG or motion JPEG and sent to a web site that allows the scene to be viewed over a web browser such as Internet Explorer or Netscape Navigator.

Self-contained HTTP web servers, the Pixord 100 and 120 perform IP assignment via the web or ARP, making it almost effortless to install.

Firmware and user content can be upgraded remotely via FTP, and control of the server is through CGI base script, making it a simple matter to integrate applications.

Events can be triggered by GPIN, date/time, frequency or motion detection.

A range of possible actions can result, including output to a GPOUT port, storage of the image to an internal buffer, FTP transmission of the image to a remote site or emailing of an image to a specific account.

Three-layer password protection is provided.

Onboard hardware includes a 32bit RISC CPU, 2Mbyte of Flash ROM, 16Mbyte of SDRAM and a watchdog chip to monitor system voltage tolerance and flag any abnormal program execution.

Two LEDs indicate network and power/system status.

The cameras have a 10base-T Ethernet network interface, RJ-45 port and RS232 serial port to connect through to an external modem.

The Pixord 120 adds an RS232/485 port to support external pan/tilt/zoom control, a GPIO with optoisolated alarm inputs, a 30V DC relay output and an external video input/output, allowing an additional video source to be connected.

A built-in CCD module offers a sensitivity of 0.5 lux and a number of video control options.

Back light compensation (BLC), auto electronic shutter (AES) and day/night options are included.

Featuring a fanless assembly, the cameras measure 168 x 77 x 54mm, weigh under 1.1kg and - for those concerned about the green qualities of an installation - feature sub-7W power consumption, operating from a 12V/1A DC supply.

The cameras are also specified for temperatures up to 50C, as well as humidity up to 80%.
