    Hi.
    Anyone knows how to display a video signal on a cell phone screen in real time ?

    Point is to see a surveillance camera with sort of virtual reality goggles, NO internet involved, no video coming trough the air, just wiring-in a composite signal. In other words, using the phone as a monitor.

    Go to Ebay and look up easycap usb to dvr converter.

    Just plug in your camera (yellow) to the converter in place of the receiver shown.

    Use on a phone here...

    Thanks. Yes, I was evaluating others alike :

    ----> http://www.ebay.com/itm/Micro-USB-E...300065?hash=item542d105d61:g:feYAAOSw0QFXDSRM

    And unsure from the description if I can get real time video into an Android smartphone or the video is recorded by the camera gadget to be played later. Also, a mental fart prevents to interpret the focal distance "from 4cm to infinity" will work for a 4 metres away target. Can anyone help reading between lines ?

    There is models with 5mm lenses, 7mm, ... Which would be convenient for not close-up images ? Seems 5mm, 7mm is the lens/camera diameter, not optical specification ¿?

    This one pictures like it does distant imaging :

    And the smartphore appears to need OTG 'On-the-go' feature...
