Samsung SPD-3750T High-resolution WDR PTZ Dome Camera (37x Zoom)
  The SPD-3750T High-resolution WDR PTZ Dome Camera (37x Zoom) has a  1/4" vertical  double density interline CCD image sensor to deliver  clear images in various environments,  and offers a resolution up to  550TVL / 680TVL (color/B&W). A minimum illumination  of 0.7 lux at  f/1.6 (color) makes the camera suitable for low- light surveillance.
  With auto-focus zoom lens (3.5-129.5 mm), the SPD-3750T  High-resolution WDR PTZ  Dome Camera offers 37x optical zoom, and 12x  digital zoom for precise monitoring,  and enables zooming in to any  distant object with 444x magnification thereby providing  detailed  imagery. It has 360° endless panning ability, -6 to 186° tilting, and  has  a maximum pan/tilt speed of 500°/sec that enables you to monitor  wide areas with  high response speed.
  Intelligent auto tracking feature has the ability to identify and  follow moving  objects automatically for accurate visual monitoring. The  SPD-3750T PTZ Dome Camera  is defined with its WDR function to correct  extreme lighting environments marked  by high-contrast and harsh backlit  scenes.
  With 3D filtering noise reduction technology (SSNRIII), the SPD-3750T  camera  offers color images in dimly-lit areas with reduced noise in  the picture, thereby  saving storage space. The high-resolution camera  with Day&Night ICR (infrared cut  filter removal) function allows  you to switch between color and B&W as per changes  in ambient  lighting, ensuring accurate color reproduction in daylight and enhanced   B&W images at night. You can easily select auto-monitoring mode  from a wide range  of predetermined parameters, as the camera supports  up to 255 preset configurations.
  Backlight compensation adjusts video gain to correct the exposure  when the object  being captured is in front of a bright light. Automatic  gain control adjusts the  signal strength to maintain a constant  brightness level, and auto white balance  adjusts the red and blue  signals by taking a standard white color reference to get  the most  natural colors. Using DIS (Digital Image Stabilization), the SPD-3750T   camera offers steady pictures by compensating for any camera movement  caused by  external stimuli. The advanced motion detection feature  detects motion without any  additional external sensor. Privacy masking  allows you to mask up to 8 user programmable  zones of a scene for  privacy reasons.
  Press tabs on each sides of the dome enable rapid connections to the  mount, ensuring  ease in installation. The multi-language OSD (On-screen  Display) offers intuitive  and convenient interface for easy operation.
  The PTZ Dome Camera can be installed in various security environments  such as  ceilings, walls, poles, corners, and railings using custom  accessories.
