Video Down-link Receiver
A down-link video receiver used for Kite and Pole Aerial Photography.
Here are some shots of my new video down-link receiver setup. The original idea was created by David Harding. The video monitor itself is a small 3.5" LCD Monitor CCTV Camera tester. The brilliance of this idea, is that the camera also comes with its own built in 12V battery. These are used to simply test CCTV video cameras to make sure they are operational. In our case we can plug in our own 2.4Ghz video receiver. I found the battery lasts around about an hour and I can piggy back a reserve usb battery on top giving some more life on the larger KAP outings. The receiver is simply attached to the top of the monitor casing with velcro and acts as a basic sun shade. The monitor provides good clear images and has automatic PAL/NTSC detection. The unit can be attached to your arm/wrist with the attached velcro strap and looks like some massive retro watch from the early seventies. I would recommend getting bigger strapping if you have more chunkier arms.
The only tricky bit is the connections. You will require a standard 1.3mm 12V DC connector from the monitor to the receiver for the power.

and then a standard adapter type connector to the receiver. I had a spare one and simply soldered the wire to make a shorter connection.
The video requires another set of different plugs. The receiver uses a 3.5mm co-ax plug and the monitor uses a 3.5mm line in type plug. The sort that plugs into audio and video.

I am sure you can find equivalents anywhere in the world.
Just two wires soldered to the positive and negative poles. Nice and straightforward. As always check your connections for continuity and required wire lengths before assembling.
