CCTV DVR: HDMI or VGA to BnC to three TVs

    Existing DVR has VGA and BnC outputs

    BnC used to feed 3 TVs via the TV aerial cable

    The upgrade box CCTV DVR has VGA and HDMI outputs only.

    How can the BnC feed/signal be replicated?

    If an A-B VGA switch was fitted at the DVR, could it be used, as the screen at the DVR is only used when at the DVR.

    I understand the HDMI route along Rg59 cable is either impossible or expensive and requires a second HDMI connection on each of the TV's
    Thanks

    Don't think that will work. He needs a vga to bnc splitter. It's a powered device that will also let him leave the monitor connected.

    Thanks for insights

    Have to port forward 3 ports and have got into the EVW3226 Ubee router where I see the following

    Public Port Range / Target IP Address / Target Port Range / Protocol (choice of UDP,TCP or both)

    I have the target IP address for the DVR, just wonder what is the Public and Target Port range
    e.g. one of them is the ubiquitous port 8000

    have yet to test it

    Okay, got it woking today and it does what he says on the box: usb powered from DVR and a vga in and out so can use old screen for local work on the DVR, however with the good quality web browser, no real need for local access

    Is there a thing called an RF Modulator that can do it? (I got it on eBay years ago for like €15-20)
    I just remembered we have one of those, but I think at the time we were told it wouldn't work with the NVR being used.
    Before it was used on just a camera showing a live feed with no recording.

    I can get that one you posted and it could send the cameras to all the TVs?

    I can't see its price.. I clicked and it showed other things and in dollars.
