Sony's EVI range of PTZ video cameras
4 July 2012
Stemmer Imaging is now distributing Sony’s EVI range of pan, tilt and zoom colour video cameras. Available in two standard and two high definition versions, these cameras have been designed for applications such as video conferencing, corporate training and distance learning. White body versions are also available for medical video conferencing and telemedicine applications.
Full high definition 1080p resolution is available with 20x optical zoom and a choice of HD-SDI or DVI interfaces. Standard definition versions are available with 18x optical zoom, or with Wide-D technology and a 28x optical zoom. Sony’s Wide-D technology combines progressive scanning and image processing to improve image display. The same image is captured twice: once at normal shutter speed and again at a high shutter speed, then the two images are combined to reproduce the high contrast of the original view.
All models can be desk or ceiling-mounted and offer an impressive pan angle of ±170° with pan speed of 100°/sec and tilt angle of +90°/-20° and tilt speed of 90°/sec. For ceiling mounted configurations, an electronic flip function electronically inverts the image of a tracked object as it passes under the dome to maintain the correct display. All models feature manual focus, autofocus and a one-push autofocus function. The cameras can also be remotely controlled through RS232/RS422 and the supplied IR remote controller.
