Description

The Web Enabled Network Controller is a LAN programmable Master Clock in its simplest form. It synchronizes its time with your local LAN or NIST over the internet. Two 120VAC solid state outputs can control clock circuits, power supplies, or auxiliary outputs such as tones, bells, lights etc. Programming is accomplished using a web browser from any PC on the network or internet.

More Details

The WeNC is an Internet/LAN based clock system and auxiliary circuit controller. The WeNC comes equipped with two 120VAC 500W solid state outputs. These outputs can be configured to control National Time's clocks as well as most popular clocks of other manufacturers. The outputs can also be used for auxiliary devices such as bells, chimes, tones etc. typically found in schools. The WeNC operates on any TCP/IP-based Ethernet network, and automatically synchronizes the clock system with any standard NTP or SNTP time server or with the official United States atomic clock time source in Boulder, Colorado. The WeNC automatically corrects for daylight savings time and power outages. The WeNC can be configured, programmed, and monitored from any PC on the LAN network through a standard browser interface and a dedicated PC is not required during normal operation. Multiple WeNCs can be utilized to synchronize multiple clock systems throughout a campus, city, district, and beyond.

About the Telecenter 21 system:

Overview

The Telecenter System 21 offers the maximum in flexibility for a total integrated system solution. Modular by design, this powerful, easy to use school communications system provides centralized control for a broad range of communication functions including: telephone, intercom, public address, audio program distribution, class change signaling, secondary clock correction and tone distribution.

Telecenter System 21's intercom/paging operation works with classroom speakers, classroom phones, and/or a call-in switch. Using their telephone, administrators can page throughout a facility or in selected areas. A built-in master clock can be programmed for hundreds of events while automatically changing schedules to accommodate holidays. The telephone features enable connection directly to outside phone lines or integration with a front office phone system. The system also provides many other sophisticated features like automatic line selection, call forwarding, conferencing, Centrex^® compatibility, call back busy, private lines, transfer and multiple trunk groups. Permission for student's access to outside lines can be granted, controlled and restricted through the use of Student Phone^™. A powerful combination of features make Telecenter System 21 ideal for improving communications in-school as well as between parents and teachers.

Intercom System

• Two-way open voice channel communications
• Classrooms can call main office using call-in switches or phones
• Normal or "emergency" call-in designation
• Call-ins indicate on a digital readout attached to administrative phones or on a large wall display
• Multiple audio channel capability allows simultaneous intercom, program distribution, and/or tone distribution to different facility areas

Master Clock & "Bells" Functions

• Programmable for hundreds of class change "bell" events
• Bell zones are independent of audio paging zones for increased system flexibility
• Automatically daylight savings setting
• Corrects analog and digital secondary clocks

Public Address/Paging System

• Distribute announcements from any phone; PIN access prevents unauthorized access to system features
• Flexible "zoning" of classroom, corridor, and outside speakers accommodates any school configuration
• Selectively exclude speakers from receiving pages, programs and/or "bells"
• One-touch emergency announcements throughout the facility

Tone Distribution

• Multiple tone types indicate different events -e.g. tornado, fire, evacuation, etc.
• One-button initiated tones or from any administrative phone

Audio Program Distribution

• Up to three audio sources (radio, CD, tape) can be sent out simultaneously
• Program distribution initiated from any administrative phone
• Digital readout prompts program distribution set-up
• Each classroom can individually select program source via classroom phone or selector switch

FCC-Approved Telephone System

• Compatible with CENTREX^®, EKSU and PBX systems
• 3-way conference calling, call forwarding, and call back busy features
• Voicemail integration
• PIN codes allow call placing from restricted phones
• A Student Phone™, with built-in restrictions, allows students to call home for a ride, etc., while preventing abuse
• The special system access function allows security personnel to dial-up computer centers, media rooms, or anywhere in the school to listen for vandals or burglars

The VR-4HD is a complete HD studio in a compact and portable package that replaces several different pieces of complex A/ V equipment. Designed with single-person operation in mind, the VR-4HD enables easy switching and mixing of sound and video using advanced video and audio Digital Signal Processing (DSP) along with dedicated hardware controls faders, buttons and touch screen interface. It beautifully integrates a digital audio mixer, video switcher, multi-viewer touch screen and USB video/audio streaming interface into a stand-alone device.

The VR-4HD features professional quality broadcast controls and switches ensuring more accurate and faster operation than interfaces based on a computer style mouse and keyboard. The ability to simultaneously switch video with the push of a button and adjust audio with the push of a fader is invaluable and puts all essential features at the operator's fingertips. The built-in multi-view screen is also a touch screen interface for accessing set-up parameters, making it extremely easy to adjust picture-in-picture settings by dragging the inset window onto the screen.

YESTERDAY'S VIDEO SOURCES
The VR-4HD has three dedicated HDMI input connectors compatible with a variety of equipment and support 1080p/1080i/720p video resolution. The fourth input includes a scaler to support both video and computer resolutions and also supports analog RGB and component input so older devices can be used as sources without the need for external conversion equipment.

Both progressive and interlace signals can be input allowing for both 1080i and 1080p signals to be used at the same time. Video signals input from a PC are accurately displayed thanks to progressive signal processing. HDCP is supported for input of copy protected content from devices such as Blu-ray disc players.

COMPOSITING EFFECTS
The VR-4HD includes DSK (Downstream Keying), Picture-in-Picture (PnP), Split and Quad composting effects ideal for creating news style broadcasts and corporate presentation content.

The DSK function is great for overlaying titles, song lyrics or logos onto incoming video sources that can be switched in the background while text or images remain displayed.The DSK supports both Luminance Keying (Black / White) and Chroma Keying (Blue / Green) for compositing two videos in one screen using Picture-in-Picture, or for using the split function - ideal for seminars and presentations.
