Selecting Mode Of Operation - Sygonix 12133D1 Notice D'emploi

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 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 operat-
ing instructions of your DVR, 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"!
