    hows it going folks...

    most of the stuff im finding on the net is from the states and is ntsc...

    what im thinking of doing is having a camera in a car but i want to view it from the side of the road.... anyone know a good wireless kit that would be able to keep a signal with a moving car.. budget would be small for this kind of thing so no gigawaves :P:P

    if anyone can help it would be great

    thanks

    Only wireless for Analogue that is legal here is 2.4Ghz video senders. Connect up an ordinary video camera (door or security camera). Some Swann cameras in Maplin work with ordinary video sender receiver.

    Much speed (> 5kmph) or distance (>50m) is a problem.

    54G VOIP on 2.4GHz may work a little better.

    id be looking for more than 50 metres.. and the cars will be going alot faster than 5mph...

    i found a system that says it can do it up to 5km away but i dont know if it can... it say its 1.2Ghz fm transmission.. would that be able to carry audio and video?

    can you use a higher Ghz up north? i know the bbc have micro links that are 5.7Ghz.. and they dont get a licence to use them...

    1.2GHz is a Licence band in all of Europe. Unless you have a Wireless Experiment/Ham/Amateur licence, it's illegal.

    5.7 ish GHz is ISM band, used by 802.11n and 802.11a WiFi. In Ireland you can't use Analogue Video senders on that band and any outdoor 5.x GHZ gear while licence free, needs to be registered with Comreg.


    Try a Video sender pair. About €50 and you can use camera or portable DVD or Laptop TV out as test signal from car.

    It which case you will probably have to go down the route of getting one of the State broadcasters to do it for you. They may be able to advise you of a a company to it for you. If it's a once off the cost would be less than buying broadcast quality gear. I "could" suggest where you can buy used broadcast equipment but I would stricken down by the hand of God.:pac:

    A decent camera will set you back a bit or you can use a Decent Prosumer WS Camcorder to feed the video sender.

    Some of the video senders are very good and close to broadcast quality, better than the modulators built into a VHS or Sky box. Interference is usually due to WiFi. The built in directional panel aerial is easily replaced by a small Omni unobtrusive magmout for exterior WiFi applications if you can solder an RG174 coax cable.

    It's worth trying.

    The next level up is professional gear than needs a licence. The cheaper end of the market (i.e. not actual TV OB units ) is this:

    I've seen live demo. It's near BBC/RTE/Eurosport quality. But it does need a licence. Comreg does issue "test" licences though.
