Features & Functions :
☉ Adopted with GM8180 SOC chip, in-built with ARM9 CPU core, with high speed, high integration, low power consumption, small but complete in function.
☉Adopted with Linux real time operation system, with strong flexibility, strong network transmission ability and stability.
☉Enhanced H.264 algorithm (main profile ) , 4 times of normal H.264 algorithm compression, makes compression files as small as 60% of those by normal H.264, especially suitable for network transmission.
☉Window and graphic interface are user friendly and easy to operate, with menu note function, can be controlled by mouse, front panel, remote controller etc.
☉Preview in D1, support motion detection, OSD, realtime listening in.
☉Support 4 channel video and audio playback realtime, support file fast playback, fastward, play etc.
☉Support max. 1x1.5T SATA HDD, support USB 2.0 for backup, CD-writer.
☉Video files could be searched by video type, time, date etc.
☉ Auto screen saver, to save energy.
☉ Powerful software supported: build-in web server, Networking access for remote live viewing, recording, playback, setting, system status
