Capable of redundant recording, full D1 recording and hard disk group management, the card features multi-playback, mobile view, disk capture and CMS functions.
Offering a digital zoom function during preview or playback, the new GAO18004TD DVR card utilizes digital watermark technology to ensure that a video file is not falsified.
Apart from full D1 recording, the new DVR card is capable of producing pure digital picture of the highest quality for playback, recording and video archiving when embedded into existing system.
The new GAO18004TD DVR card is not only easy to operate with a user-friendly menu, but also maintains a low bandwidth video compression stream while offering better image quality upon restoration than other compression schemes by using H.264 Main Profile.
Compatible with Windows 2000, XP, Server 2003 and Vista operating systems, the new DVR card provides 4 channels video input and 4 channels audio input. With the help of this DVR card, different channels can be set to different recording times.
