Westminster's Sentry Scope is a whole new approach to surveillance video. Unlike conventional cameras that take an entire image at once, Sentry Scope 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.
Sentry Scope is a true breakthrough in security video
Conventional PTZ systems can monitor large areas in high resolution, but only if the operator continually points the camera in the right direction and zooms to the correct level. If the operator misses a critical event, so does the recorded video. Sentry Scope solves this problem by recording the entire region in ultrahigh resolution, 100% of the time.
Key Features
- Wide Panoramic Images;
- Monitor up to a full 90º field-of-view
- Ultra-High Resolution;
- 21 million pixels per image; recognise faces and license plates to 200 feet (60m)
- Unmanned Operation.
- Records the complete field-of-view in the finest detail, even when security officers are distracted or not present
The Sentry Scope 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 line to 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 is unmatched image clarity and detail.
Use in a Network or Stand-Alone
Sentry Scope has been designed from the ground up using advanced digital technology. A dedicated Fast Ethernet link connects the main camera to its control unit, Sentry Server, 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. Sentry Server controls the camera, records the video, and manages the display of both live and stored images.
Simply attach a keyboard, monitor and mouse to Sentry Server for stand-alone operation. For the most power, place Sentry Server on your Local 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 Sentry Server 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 Sentry Scope camera on the network. A simple program, SentryViewer, displays clips of 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 images can be exported as bitmaps or CD video clips.
A screen shot from SentryManager is shown below, illustrating its ability to monitor and control multiple Sentry Scope cameras from a single remote location. See the SentryManager brochure for more details.
Capture all the Details
- Always records the entire area, even when zoomed into live or recorded video;
- A full 90º horizontal field-of-view;
- Up to 21 million pixels per image; over 250 times the resolution of typical CCTV.
Manage Stored Images
- Record all images, only those with motion or external trigger, or on a weekly schedule;
- Rapid Search quickly locates recorded events of interest by time, area, motion or triggers;
- Export images as bitmaps or CD video clips.
Customize the Field-of-View
- Increase the recording time and image rate by only viewing essential areas;
- Adjust the image width from 36º to 90º to precisely match the monitored region;
- Define up to 4 masking zones for privacy.
