SensorTec Multi sensor system ST-CHD825-1000

SensorTec Multi sensor system ST-CHD825-1000

Multi sensor system (MS) is composed of a Day/Night Camera, Thermal Camera mounted on a pan-tilt unit. Day/Night and thermal cameras are installed on the same optical axis with a deviation of less than 0.05 dgr. The videos from both Day/Night and thermal cameras are available simultaneously as digital video MPEG4 or H.264. MS includes a built-in test and status mechanism. All video distribution to viewing workstations is done digitally. Both video digital streams have low latency.

Functionality

Multi sensor system is equipped with day and night vision system and allows observation under all weather conditions even in fog, rain or snow. There is a thermal camera and a day-night high resolution camera with very high optical zoom placed on a movable pan & tilt platform. The platform will be able to turn the cameras in all directions, both in azimuth and elevation and controlled from the vehicle’s operator place or remotely by the existing C&CC. The movable platform –pan tilt can accept different commands from the C&CC like home position, extremely slow speed, high speed, variable speed in small steps-continuous, panoramic observation with constant speed, tour mode.
A standard protocol is used. Day/Night and Thermal cameras have continuous optical zoom and continuous digital zoom. The System will provide stable picture in windy conditions with known – proven methods. The method chosen by the contractor will fulfill the end user expectations.

Construction and connection

The operator at the C&CC will be able to monitor the status of this power supply system. All data signals output from the MS can be sent to C&CC over a single Ethernet connection

Coolecd MWIR Thermal Camera

ST-C Series cameras are a range of cooled Medium Wave Infra-Red (MWIR) thermal imaging cameras. They employ the latest focal plane array technology to meet long-range surveillance and target identification requirements. ST-C Series have a very high life span (2 times higher than most cameras in this range) because they are fitted with long life cooler and use HOT detector type (XBn) that runs at higher temperatures than regular InSb detectors thus expanding the lifetime of the cooler. ST-C Series camera incorporate continuous zoom lenses with autofocus and F/4 to ensure high sensitivity even with high magnification. This makes ST-C Series camera an ideal tool for very long-range observation over sea and land.
