The MIC-612TFALD36N Dual Thermal/Optical Camera (Sand, 35mm, NTSC) from Bosch has been designed to offer an extremely reliable, robust, and high-quality surveillance solution for security applications that demand excellent performance. Precision engineered to exacting standards, the camera offers a ruggedized dual optical/thermal image capture solution.
Image control and quality are integral aspects of any PTZ camera, and the MIC 612 delivers. A high-quality day/night camera core with 36x optical zoom lens and a full 12x digital zoom, and a high-performance, un-cooled thermal imaging core sit side-by-side within the housing. The MIC 612 has two video outputs: one for the optical camera, and one that is user-switchable between the optical camera and the thermal imager. The optical camera provides 550 TVL of horizontal resolution for outstanding clarity and image detail, and incorporates Wide Dynamic Range (WDR) that dramatically improves the dynamic range by 128 times and results in clear image reproduction in extreme, high-contrast environments. Features of AutoScaling (proportional zoom) and AutoPivot (automatically rotates and flips the camera) ensure optimal control. Day/night capabilities and outstanding sensitivity make the MIC 612 an exceptional performer in all lighting conditions. In low light, the optical camera automatically switches from color to monochrome by removing the IR filter to boost sensitivity while maintaining superior image quality. For operation in the darkest conditions, the SensUp control feature automatically reduces the shutter speed to as little as 1 second. This increases sensitivity by more than 50 times. In addition to low light applications, the optical camera is an exceptional performer when viewing under a sodium vapor lamp (for example, a street or tunnel lamp), which normally gives a yellowish tint to images. The camera automatically compensates and restores objects to their original color. The thermal imager has user-selectable color options including White Hot, Black Hot, and many others, and built-in sun protection that allows the camera to self-heal if pointed directly at the sun. Standard-resolution models also have a user-selectable on-screen temperature display (spot meter) and alarm.
Subjected and certified to rigorous ingress certification tests, this camera is perfectly suited for installation in even the most unforgiving environments, thus eliminating the need for pressurization. The camera is machined from solid aluminum and protected from corrosion by 2 different processes: first, it receives a coating of Alodine 5200, a chromate conversion coating of aluminum that is used in the aerospace and defense industries, where a protective layer is required to improve corrosion resistance. Second, it receives a robust, powder-paint coating. The camera is sealed with ‘O’ rings and can operate submerged in up to 3.3’ (1 m) of water for sustained periods of time (a maximum duration of 24 hours). It is not rated to be installed permanently under water. The thermal camera will show no detail if submerged.
