Profile: Plettac Security UK Ltd. manufactures and supplies CCTV cameras & related products. We provide monitors with 100Hz technology. Our digital technology is used to present video signals at double the speed - 100Hz instead of 50Hz seen in conventional monitors. This improves picture quality considerably and is easier on the eye for the observer. These monitors are built to MPRII standard. They operate with a reduced magnetic and electrostatic field. This minimizes both the stress reaction to the magnetic field and the risk of skin irritations resulting from excessive radiation. We also offer security cameras, which produces pictures even in extreme darkness.
