Product performance introduction |
 |
Using PHILIP TriMedia 1500 DSP to realize 4/8 channels real-time CIF video and audio compression. The 4 channels card and 8 channels card can be dynamically adjusted and realize 1/2 channel full real-time D1 video and audio compression respectively. Use H.264 compression algorithm. The images are clearer and the bitrates are lower. Using many patent technologies in the compression process to ensure the lowest bitrates in equal image quality and playback occupies system resources is very low. Using a revolutionary design concept, the images quality preview breaks through 350. Using more optimized data sampling and processing model, the video quality is clearer and strengthens images processing tache, reduce the yawp effect to code. The hardware is designed elaborately. It can reduce the disturbing that brought by hardware device and ensure the stability of the images and low power consumption. The power consumption of 4 channels card is less than 1.8 W. The system is more stable。
Unique intelligent quick playback function：
According to the user set area whether exits moving to determine the speed of playback, and improve the retrieval efficiency。
Unique hardware watch-dog function：
The cards integrate hardware watchdog function and can solve the DVR hardware or operating system malfunction effectively to realize no attendants。
