Most trail cameras use only one image sensor to capture images 24 hours a day. So you settle for daytime images that are less sharp and rich, and nighttime images that lack consistent illumination and range. CORE Dual Sensor (DS) Technology gives you two image sensors one optimized for more sharp and rich images during the day and another optimized for images with consistent and further illumination at night. Whether you're hunting from a ground blind or a deer stand you can plot their movements more reliably and plan your hunts more strategically.
