Boasting WDR Pro technology, the SD8311E/21E can also cope with challenging lighting conditions and generate image quality similar to the capabilities of a human eye. With sophisticated pan/tilt mechanism, the camera provides fast, precise movement with continuous 360-degree pan and 90-degree tilt. Users can easily control the lens position via a mouse or a joystick to track the object of interest in and set up to 128 preset positions for patrolling.
