8. Selecting Mode of Operation

The surveillance camera offers 4 different operating modes or video output signals to be compatible 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 available 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 camera; 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"!
