8. Selecting Mode of Operation

The surveillance camera offers 4 different operating modes or video output signals to be com-
patible with different DVRs:
• CVBS (analogue standard PAL-/NTSC-video signal)
• AHD ("Analogue High Definition")
• CVI ("Composite Video Interface")
• TVI ("Transport Video Interface")
In the operating mode "CVBS", the camera supplies an analogue standard PAL video signal
that can be displayed on any conventional surveillance screen and that can be recorded on the
corresponding DVRs.
In operating modes "AHD", "CVI" and "TVI", the camera supplies a high-resolution video signal
(960p) that offers a much better picture quality than "CVBS". However, you need a special DVR
to view and record this high-resolution video signal.
The display and recording of a video signal in the operating modes "AHD", "CVI" or
"TVI" with a conventional analogue DVR (which only has CVBS video inputs) is not
possible.
You absolutely need the corresponding DVR that supports either "AHD", "CVI" or
"TVI". Observe the operating instructions of your DVRs on what operating mode you
need to set at the camera to make it match your DVR for this.
If you do not use a matching modern DVR yet, you can use the surveillance camera
in the operating mode "CVBS". However, you will only have normal video quality avail-
able then, rather than a high-resolution signal.
If you want to connect the surveillance camera right to the screen (without the detour
via a DVR), the screen must support the operating mode set at the surveillance cam-
era; otherwise, no picture (or only interference) will be displayed.
If your screen supports only a conventional CVBS video signal (e.g. every TV as well
as some computer screens), you cannot use the operating modes "AHD", "CVI" or
"TVI"!
The benefit of the modern operating modes "AHD", "CVI" and "TVI" is that you can transmit high-
resolution video signals (960p) via a present coax-cable with them. Therefore, it is sufficient to
replace old surveillance cameras and DVRs with modern devices (with "AHD", "CVI" or "TVI").
The difficult installation of new cables is not required.
