Telvue HD Broadcasters
0
The TelVue Hypercaster provides IP origination for digital broadcast channels in MPEG-2 or optionally H.264. It sends it signal over gigabit ethernet which can be received and converted back into a signal that most cable head ends can utilize. It offers 8TB of solid state RAID 5 storage standard and can be managed via a web browser.
The Princeton B3000 offers a more traditional approach to distribution of HD-SDI (and simultaneous SD) programming. It offers 2TB (expandable to 4) of RAID 6 storage and can integrate with a NAS or SAN if more storage is required. Many functions such as content management, playout and capture scheduling can be done via the web interface.
HD Pan/Tilt/Zoom Cameras
0Although we’ve been deploying Cisco PTZ cameras with our video conferencing installations, I was on the lookout for cameras that might be used in a studio situation for Duke Chapel’s exploration into HD upgrade or other facilities where a camera with expanded dynamic range would be required.
The new Canon XU80 has a 1/3 CMOS image sensor and 20x zoom with 180° pan and +220°/-40° tilt. It features fast, quiet and precise pan and tilt movements and can be mounted upright or upside down. It also has a low light capability through the slow shutter function. The camera will sell for about $10,000.
At the higher end of the spectrum, the Panasonic AK-HC1800G features a 2/3 type 3CCD sensor with 2.2 megapixel resolution and a variable frame rate function that can produce film-like images. It has extraordinary low light sensitivity and a 12-axis color matrix adjustment. At $28,240 list for just the camera (lens and pan/tilt housing separate) it would be an investment but would most likely produce exceptional images.
More comparable with the Canon is the Panasonic AW HE120 which was recently released. It features a 20x zoom lens and 1/3 type Full HD 3MOS as well as 16-axis color correction and Panasonic’s exclusive dynamic range stretch feature. It can be controlled via Crestron (or other RS-422 controller) or directly via a web browser and can store up to 100 camera presets. The camera’s list price is $8,900
LogicLight from LogicKeyboard USB Keyboard light
0
The LogicLight from LogicKeyboard is a USB powered light to help illuminate your keyboard in low light situations. I thought it might be good for Duke Media Services or Duke’s Theatrical Department who may have to use computers in situations where lighting might not be conducive for computing. Sells for around $20.
New Hitachi Remote Camera
0
The new Hitachi HV-HD33 is designed for applications where high sensitivity, low-noise, and low-user intervention operation are required. It uses a 1/3-inch C-mount lens. The camera has the distinct advantage of outputting SDI at multiple frame rates and TV signal standards.
Ikegami’s HD Camera Does Well In Low Light
0
The Ikegami HDL 45E features a 2/3 inch 2.3 Mega pixel AIT CCDs for low noise low light applications. By using 1920×1080 pixel sensors, there is no conversion performed within the camera - the full resolution from the sensors in maintained through to the camera output. Full remote control can be achieved through Ikegami’s remote control devices.
TVU Networks TVUPack Mini Connects Cameras Over Multiple Networks
0
The TVUPack Mini uses multiple 3G/4G/Wifi connections to transmit HD video taking the place of more expensive 2.4GHz Wireless units. It has 8 USB data card slots and can even become it’s own hotspot. The transmitters sell for around $6500and feature a small confidence monitor and the receiver is around $10k. You can remotely monitor the cameras and the combined signal strength of the transmitters.
Tiny Hitachi Has Full HD Resolution
0
The Hitachi KP-HD20A features a high sensativity 1/3 in 2.1Mpixel HDTV color sensor in an ultra-compact package (4.6 ounces and 1.7″ x 1.7″x 3.1″). It is full 1080p with dynamic contrast compensation and is controllable by standard RS232.
Glidecam Small Camera Stabilization
0
At $299 list, the Glidecam XR-1000 is flexible enough to handle different types of small cameras weighing up to 3 pounds. Their offset, foam cushioned, Handle Grip is attached to a free floating, three axis Gimbal. This allows your hand to move up and down, and side-to-side, thereby isolating your hand’s unwanted motions from the camera. This up and down movement alleviates bouncing and pogo-type action.
