Function:

Based on C/S,B/S, WINDOWS2000 SERVER operation system

1～16 channel picture display,real-time recording/replay/,synchronous audio
Synchronous recording/replaying/carving/web transmission,excellent system frame,normal operation while CPU is overloaded
Dynamic data rate adjustment: adjust automatically video data rate according to change of video image,storage capacity: 80—300M/hour

Circular recording: support multi hard disks circular recording/full disk circular recording automatically.If users quit/remove one of the physical disks,recording data is ignored but system won’t be distroyed

Synchronous upload of alarm information & video image,64 IP address is uploaded synchronously.,show real time uploaded video image & alarm information then indicate with voice and buzz even if computer doesn’t connect with video   

Alarm area setting: motion detecting support 396 alarm area per picture
Alarm sensitivity adjustment & map oriented display

Automatically pass video data rate to back-end storing server to store long-distance record,local recording or non-recording is selectable without affecting video recording of back-end server

Dynamically detect operation of network card, local recording function automatically start up while network card doesn’t work normally, locally stored video image is automatically uploaded to back-end storing server while network card operate well again

Customer-end software can connect with server and provide other customer-ends with video signal as a server itself

Web monitoring end support real time monitoring for 64 IP address image,real long-distance centralized monitoring can realize
