DVR 4000 is the perfect security and surveillance solution for home, office, school, factory, building and general use. It is a 4-channel DVR (Digital Video Recorder) that offers real-time video/audio recording and playback. Digitally recorded video is optimally compressed yet retains excellent image quality.
DVR 4000 integrates traditional security devices, controls remote PTZ cameras, and features remote monitoring, recording and control of multiple sites simultaneously. Its advanced motion detection feature avoids false alarms, and provides several methods to notify about intrusions or abnormal situations instantly. Its complete access control and audit log ensure a true secured environment. DVR 4000's hardware watchdog, SmartFile allocation and database-based video recordings guarantee system stability as well.

Excellent Display Quality and High Compression Ratio
With the complete integration of software and hardware, DVR provides excellent image display quality. It displays true 640x480 resolution images and eliminates the 'ghost effect' in motion video. HM (MPEG4-like) compression is mainly designed for CCTV applications. It provides near loss-less video quality and saves a great deal of disk space.

Smart Saving during Recording
DVR automatically determines the recording frame rate based on the amount of movement. Lower frame rate is used for more static video, and higher frame rate for full motion video.
