Infra Red extender

[oliverb]

I am looking for a really basic infra red extender.

I want to control my video camera from inside my house. The camcorder will be fixed in place and have power supplied from the house.

I want to be able to point the remote control at a reciever LED then repeat the control signals via wire to a transmitter LED by the camcorder.

The distance will be max 20ft.

I have enclosed a pic.

I presume I can just use a transister to amplify the signal and send it by wire to an infra red tranmitting LED.

Thanks in advance.
Brett.

here's something you could try on a breadboard, real quick and easy

transistor sees incoming ir, and turns the ir emitter on and off

couple reasons it probably wont work:

1) transistor is going to be saturated with ambient IR
2) transistor doesn't have enough gain to switch the current of the IR emitter
3) transistor needs to be shielded visibly from emitter so it doesn't see its own signal

it might work in the dark?
