1. The MDVR has a G sensor?  

Re: yes, SDM605 supports G-sensor


2. The MDVR can send data and or events over 3G?

RE:Yes, the DVR with 3G function will send the live data and video over 3G


3. The MDVR can be set to send all video on storage card to a web server if the MDVR is connected to WIFI?

Re: Yes, there are 3 ways for you to get the videos on the storage card. 1st, you just download the video directly from the SD card or harddisk. 2nd you could remotely download the videos or GPS tracking through our Clients software. 3rd way, you could download the videos by a certain schedule through wifi network.


4. The MDVR can be set to send an alert to the customers email or SMS? 

RE:Yes, same as the above question, our system supports email or SMS sending, they work with server.


5. The MDVR can be customized based on alerts and parameters?

RE:What do you mean by this question? Yes, we could customize for customers, but usually we have to know which exact requirements and functions you need from our device and system, then we will check and make sure if we could do for you. So could you tell me more details?


6. The MDVR compression rate? If we have a 60 second video of an event what is the size of the video?

Re: our compression is H.264, In fact, for the size, it depends on the video quality level you choose and frame ratio, like for CIF it is 1.2MB for 60S video. For D1, it is 3MB~15MB based on different frame ratio.


7.    THE MDVR can we customize the alert to send recorded time 30 second before the event and 30 second after the event for a total of 60 seconds for a crash detection?
