This 3G active DVR system is integrated with the 3G mobile technology to provide seamless
protection at anytime, from anywhere. Mobile surveillance is easy without the need to install
additional software to your 3G mobile phone. When an invasion is taking place, the exclusive
human detection technology will determine the accuracy of this invasion and make a 3G video
call within 5 seconds to show what happened and allow users to make necessary DVR or
camera control. You can also call back at anytime for instant remote surveillance.

3G DVR system is combined with one 3G DVR, one 3G server (optional), one human detection
camera and its RDID controller (optional), at least one 3G WCDMA mobile phone (optional),
and at least two USIM cards (optional).
With one 3G DVR and one 3G server, the mobile surveillance for 3G active call-out can be
achieved easily; when one human detection camera is added, the 3G mobile surveillance is
optimized with the “Ambush” function to allow you actively and secretly inform other people
you’re in danger via a 3G video call.
‧
3G server:
You can treat this 3G server as the 3G mobile phone for the 3G DVR. When an event
happened and is detected, the DVR will make a video call to you via this 3G server (Active
3G call-out). You can also make a video call back to the DVR by dialing the phone number
of this 3G server.
