Functional MDVR approximately has above kinds of accessories,the 4 pin test cable is just used
during the test, please do not use it on the installation. When installed, recommend to use the 4 pin
audio extended cable. Function model MDVR need to use the 4 PIN-AV when connect to the audio
input . it doesn't need to use this cable if it is only video input, and use the AV interface in the front
panel only. External interface of functional MDVR can choose from WIFI/3G/GPS, so the relative
module antenna is needed . Video cable of the simple MDVR is aviation head. So there will be
some differences between the corresponding interfaces .As Figure 2-11.
