The HD4D is a high-resolution True Day/Night camera that switches from color to black and white mode, depending upon available light. The HD4D uses a removable infrared (IR) cut filter in color mode and an optical low-pass filter (OLPF) in black and white mode, guaranteeing optimal image quality at any time of day.
The HD4D incorporates the latest DSP (Digital Signal Processing) and DNR (Digital Noise Reduction) technology to produce extremely sharp and clear images regardless of lighting levels. DNR removes noise artifacts, increasing the performance of motion detection and typically providing longer recording durations on digital and network video recorders. Producing 540 TV lines, the HD4D reproduces sharper images down to the smallest detail with outstanding accuracy.
