The Power of Linescan

SentryScope is a whole new approach to surveillance video. Unlike conventional cameras that take an entire image at once,SentryScope uses advanced linescan technology, acquiring each image one line at a time. Military aircraft and satellites have long used this method for ultra-high resolution reconnaissance and weather observation. The SentryScope camera contains a linescan image sensor and a precisely controlled scanning mirror. At each instant of time the sensor records only a narrow vertical line in the monitored area. The motion of the scanning mirror causes this vertical lineto sweep across the area from left-to-right in about one second. Up to 10,240 vertical lines are recorded during the scan, forming the full image. The result? Unmatched image clarity and detail.

Use on a Network or Stand-Alone

SentryScope has been designed from the ground up using advanced digital technology. A dedicated Fast Ethernet link connects the main camera to its control unit, SentryServer, located in the security office or other protected area. All adjustments to the camera are made electronically from this remote point, not at the camera location. SentryServer controls the camera, records the video, and manages thedisplay of both live and stored images. Simply attach a keyboard, monitor and mouse to SentryServer for stand-alone operation. For the most power, place SentryServer on yourLocal or Wide Area Network (LAN or WAN).Network operation allows an almost unlimited number of cameras to be viewed and controlled from multiple locations.

Advanced Display Software

Three software packages allow easy viewing of the ultra-high resolution video. SentryWare is run on SentryServer for viewing images in the stand-alone mode. SentryManager is used on network computers running Windows 98 or later, providing control and image access to any SentryScope camera on the network. A simple program, SentryViewer, displays clip sof saved video, such as evidence stored on CD. All three programs are simple to install and use. Familiar “point and click” commands control the viewing of live or recorded video. State-of-the-art image display tools extract every drop of information. Video and image scan be exported as bitmaps or CD video clips.
