The TF-HCF-CAM is the smallest Military Grade 3G-SDI/HD-SDI camera available on the market. Milled out of a solid piece of 7075-T6 aluminum, the TF-HCF-CAM is rugged enough to be installed and operated in any Military or commercial application. While measuring at only 80mm x 30mm x 30mm the TF-HCF-CAM can be installed in tight areas using the robust mounting bracket included with the camera. With dual simultaneous outputs, the TF-HCF-CAM can be used with multiple devices at the same time where the 3G-SDI/HD-SDI output can connect to a DVR and the analog output can be used to view the live feed on a Garmin G500 or similar monitor.
The TF-HCF-CAM features a Panasonic 1/3” Imaging Sensor which outputs a 2MP image in high definition. The TF-HCF-CAM comes in a variety of lens options which provide specific field of views ranging from extremely narrow to ultra-wide. The electronic shutter helps preserve the image quality when capturing fast moving objects with minimal image distortion, image blur and shutter noise. The auto day & night feature is helpful when capturing images in low light areas, where the TF-HCF-CAM will automatically switch to a monochrome image if there is not enough light reaching the imaging sensor.
Helical-Centroid Focusing (HCF)
Helical-Centroid Focusing is a unique and effective method for focusing a camera typically found in high end military applications around the globe. This method of focusing is accomplished by increasing or decreasing the relative distance between the image sensor and lens which provides a large FOV range when compared to conventional lens focusing techniques. When capturing images at close range, the helical centroid focusing feature allows for very fine adjustments to achieve the perfect focus of any object.
The TF-HCF-CAM has a built-in anti-vibration methodology which is used to securely mount the Panasonic sensor to the aluminum body. This feature prevents vibrations from outside sources reaching the sensor, preventing the picture from becoming blurry or get the “jello effect” commonly seen in other cameras.
Image Processing Features:
The TF-HCF-CAM features a wide variety of image processing attributes which come standard with the camera. Some of the many features include different Exposure modes, Backlight adjustment, DNR settings, Lens Shading, Dynamic Zoom, Image Mirror and/or Flip, Privacy and Motion Sensing, Image Sharpness, Day & Night Settings, Image Defogging, Gamma Adjustments, etc.
Global Shutter vs Rolling Shutter
For those who are not familiar, “rolling shutter” is a technical term referring to the way the image sensor scans the image. If the sensor employs a rolling shutter, this means the image is scanned sequentially, from one side of the sensor (usually the top) to the other, line by line. In contrast to that, “global shutter” is the technical term referring to sensors that scan the entire area of the image simultaneously.
2.9mm Lens = 175° Horizontal Field of View (Ultra-Wide)
3.4mm Lens = 105° Horizontal Field of View (Standard)
8.0mm Lens = 48° Horizontal Field of View
16.0mm Lens = 25° Horizontal Field of View (Zoomed in)
