Extreme CCTV's MX4 cameras incorporate Extreme's MFP technology, a photocell-controlled filtering technique that eliminates problems such as focus shift and IR bleed. The LXR-type CCD delivers spectral response in both visible and near infrared regions, characterized by low-smear, low-streak and anti-blooming characteristics. The result is a day-night camera, with brilliant color performance by day and ideal Night Vision under infrared.
