Product Summary

The TW2804 is a high quality NTSC/ PAL video decoder, which convert analog composite to digital component YCbCr for security application. The TW2804 contains four 10-bit A/D and proprietary digital gain/clamp controllers and utilizes proprietary techniques for separating luminance chrominance to reduce both crossluminance and cross-chrominance artifacts. The TW2804 offers two differently scaled video outputs with 54MHz ITU-R BT-656 format for security system design. Four built-in motion detectors can also increase the feature of security system.
