Dome camera with digital noise reduction (DNR) technology is built into the camera to eliminate any noise associated with low light environment. Ghost and blooming effects are reduced dramatically, leaving the image clean and vivid. An added benefit is that the hard drive required capacity for DVR recording is substantially reduced by up to 70%, due to the DNR technology. Day and night digital control function is embedded within the camera to enhance picture quality. Day and night digital control technology automatically detects day or night time to keep full color in day time and turn to B/W at night. It also detects the environmental brightness automatically. Star Lighting mode will be working while the brightness is low. This ensures the picture brightness which can reach to 0.001lux. The camera can easily set up any function through the on-screen display menu. The privacy masking function enables you to select and record only chosen coverage among 4 areas. Up to 4 motion detection areas are available for setting. It is adjustable on location or size and an alarm will be alerted on screen.
