Adapt a digital camera to a CCTV system.
Can this be done? There are many useful second-hand digital cameras
available these days and I need to know what sort of camera output is required to convert to a coaxial video cable of a CCTV setup. Is HDMI suitable. Peter |

Peter If the camera only has HDMI outputs and the CCTV has only NTSC inputs then you need to buy a converter box that is likely going to cost more than a CCTV camera. That's a pity because good superseded cameras are very cheap. There must be SOME way to do it? |

That could be a nice little business venture for somebody... ;-p -- teleportation kills http://tinyurl.com/androidphotography |

You can do it but the quality suffers a bit. eg. http://www.ebay.co.uk/sch/sis.html?_...C+Standard+TVs Choose wisely and you can get a digital camera that outputs TV video. But beware they tend to cook themselves if used in their video mode for very long and some will even go into thermal shutdown. Basically it is a bad idea unless you have specific requirements like single frame video capture for animation or similar. Webcams are cheap and these days some are really very capable - better than many CCTVs. -- Regards, Martin Brown |

But "older" cameras aren't likely to have anyting but composite output. I think all the digital cameras I've accumulated (except for that Apple one) have the ability to connect to an analog tv set, but I sure don't have a digital camera with hdmi output. Michael |

But beware they tend to cook themselves if used in their video mode for very long and some will even go into thermal shutdown. But, if I connect a tv set to my Canon point and shoot, the tv screen becomes the viewing screen. The picture is "live", I'm not taking pictures or using it like a movie camera. The tv screen shows what the LCD screen on the camera would show, and that's a live feed of what the camera is seeing. That sounds exactly what the poster wants. Let something else down the line record it, if recording is needed. Of course, some buffer may be needed since that composite output isn't likely to be able to drive long cable lengths. Basically it is a bad idea unless you have specific requirements like single frame video capture for animation or similar. Webcams are cheap and these days some are really very capable - better than many CCTVs. Except once you start using webcams (which can be had quite cheaply at this point so long as you can live with low resolution), you have to feed them into a computer to actually get a picture. Or get a converter to output an analog tv signal. Michael |
