Video/Audio inputs
•
The picture in 2.2 above shows 2 x15-way D-Sub connector for a 16-channel Mobile
DVR. A 4-channel Mobile DVR will have 1 of these 15-way D-Sub connectors. An
8-channel unit would also have 2 15-way D Sub connectors.
•
Cameras are connected via 15 way D-Sub “pig tails” which are provided with the
Mobile DVR.
•
The camera end of the “pig tails” are clearly marked “VID 1, AUD 1” etc to
distinguish between video and audio inputs.
•
The 4-channel Mobile DVR uses one set of “video + audio pigtails”, each with 4
video and 4 audio connectors.
•
The 8-channel unit uses two sets of the same “video + audio.pig tails”.
•
The 16-channel units use two different sets of “video + audio pig tails”. N.B on 16
channel units
ONLY
the first 2 channels of each bank (i.e. channels 1, 2 and 9, 10
have audio).Audio Inputs require a line level input (2.0-2.4Vp-p,1k
Ω
)
•
Video Inputs are normal composite video ( 1V p-p 75
Ω
)
Alarm Inputs
•
There are 8 alarm inputs. Each input can take direct 12/24 volt vehicle system feeds..
The alarm inputs are connected as follows.
Pins 1 to 8 are alarm inputs 1 to 8 respectively. Pin 9 is ground and must be connected.
The alarm off state is between 0 – 5 VDC with reference to ground. From 5.1VDC – 50VDC
