Product description
Legend IP™ is a line of advanced PTZ domes that stream digital video. Digital video is easier to transmit,
share, and store than conventional analog video signals. Digital video systems also integrate well into most
communications and media networks and are easily operated from software applications that manage digital
video, such as GE’s SymSecure™ or SymNav™. SymSecure is GE’s complete digital video management
software. SymNav is GE’s free digital video viewer that is provided with each dome. Compatible software
applications, like these, allow you to control your domes and video over an IP (Internet Protocol) network from
computers, instead of using analog keypads, recorders, multiplexers, and switchers.
Legend IP domes use an MPEG-4 video encoder to compress and digitize streaming video that is of up to
30 fps (frames per second) for NTSC and up to 25 fps for PAL. At the maximum frame rates, the domes
require a bandwidth from 1 to 2 Mbps (Megabits per second). The encoder supports QCIF, CIF, and D1 video
resolutions. The MPEG-4 video stream that is created is compatible with GE’s SymDec family of MPEG-4
recorders, SymNet family of MPEG-4 codecs, and Video Navigator™ software. The Legend IP interface is
open to allow compatibility with third party software and recording equipment.
Besides their networking ability, Legend IP domes also feature powerful cameras, SilkTrak™ direct-drive
positioning for smoother camera travel, a graphical programming interface for easier customization of camera
settings, passcodes for protection against unauthorized access, and the ability to flash software upgrades over
your IP network using a standard web browser.
The Legend IP protocol is backward compatible with the Digiplex protocol. You can replace older domes in an
existing Digiplex system with Legend IP domes. You must, however, replace the entire dome (camera,
housing, and mounts), because the hardware is not backward compatible.
Be aware that digital Legend IP domes have greater power requirements than do CyberDome or analog Legend
domes. Refer to
Power requirements on page 11 and Power cable size and length requirements on page 11.
For additional details, refer to the data sheet and the Legend IP User Manual (1055713) for product
specifications and programming and operation instructions.
Installation overview
The installation of domes has been made much easier with many of the innovations that are now available in the
Legend IP line of domes. To start, all cable connections are now built into the housing. The Ethernet cable
provides both video and data. You can also connect UTP and coaxial cables for analog video and data, if
desired. Cameras operate using the housing's memory, since programming is now stored in the housing. This
allows you to replace cameras or move them between housings without having to reprogram them for each new
site.
After installation, programming will be completed by using either the web-based programming menus from a
PC, or the graphical menus on the analog video output. Both methods provide the same programming menus.
Optional installer, administrator, and operator passcodes are available to protect the dome from unauthorized
access. By default, no passcodes are enabled. For details, see
Chapter 5, Using passcodes on page 47.
CAUTION: To ensure the security of your surveillance system, your IP network should be isolated and secured from
unauthorized access.
