     FQA:

     ---

     1. Q: Does the MDVR support Hard drive and SD card?

     A: Yes, HDD version MDVR supports SSD, HDD, and SD card. SD card version MDVR supports max 2 SD card.

     The storage capacity can be from 32GB to 2TB.

     2. Q: Is it difficult to install MDVR into the vehicle?

     A: Actually it is easy to install it into vehicle. Most driver can figure out how to connect the power cables.

     And the camera installation is more easy. Just screw, connect and mount on the target place inside the vehicle.

     3. Q: If I need door open and close alarm, overspeed alarm, reverse video, brake video, left-turn video, right-turn video, etc,

     is it available?

     A: Definitely yes!

     The I/O RS232 and 485 extension port is for all expanded purposes, including the functions above.

     In fact, there are more customized functions which can be connect through this port, such as Fuel sensor, Counter system,

     PTZ camera, and so on.

     4. Q: We have our own platform and server, can we use your MDVR? Do you have SDK or can you do customized platform for us?

     A: Yes, we have SDK ready and welcome your OEM customized order!
