Description

The TW2867-QLC1-CR is an electronic component model that falls under the category of Encoders, Decoders, and Converters. It is manufactured by Techwell, Inc. This component includes four high-quality NTSC/ PAL video decoders, which convert analog composite to digital component YCbCr for security applications. It also features 10-bit A/D and proprietary digital gain/clamp controllers, as well as proprietary techniques for separating luminance and chrominance to reduce artifacts. The TW2867-QLC1-CR is designed with high-performance dual scalers in each channel, offering two differently scaled video outputs with a 54MHz ITU-R BT.656 format. It also includes four built-in motion detectors to enhance the security system's features.
