| Specifications︰ | Description:4 channels video and audio input. H.264 hardware compression. 80-120M/hour. Best image quality. Support PTZ and remote control. Max 16 channels alarm in/output by alarm box. Can build 4-24ch realtime video and audio synchro system.
ET-404H series card uses fully optimized algorithm based on Total-Hardware-Solution to realize video/audio real-time encoding, moving video capture and preview, audio preview and motion detection, etc. Its advanced motion detection feature avoids false alarms, and provides several methods to notify about intrusions or abnormal situations instantly. The video image and compressed code-stream can both be transmitted directly to the SDRAM from ET-404H series compression card. The transmission doesn¡¯t require the cooperation of CPU. 24-channel audio input can be performed in one PC with stable and reliable performance. Each channel can perform real-time encoding simultaneously, and also the encoding control parameters of each channel are fully adjustable independently.
