808 Keycam recording with Remote control

Hi there.
i want using my keycam with the remote controler.
for that i want using the channel from the original vga camera from my copter.

i have 3 wires for that:
red/black give 5v power(ideal for the keycam)

red/white has constant power of 0v and give short pulse of 3.3v if i press button on remote control.

black/white has constant power of 3.3v and give short pulse of 0v if i press button on remote control.

so i looked on the picture of the board from here:

The lower right connection on the power button.
This controls when the power button is pressed; connect it to an output. Driving this pad low (0v) presses the power button, driving it to 3.3v releases it.

The upper right connection on the mode button.
This controls when the mode button is pressed. The voltages on it are the opposite of the power button: 3.3v presses the button, 0v releases it.
So it seams perfect to control with remote, but it wont work.
I just connected the wires for the "record" button, pressthe key on the remote and nothing happend.

do i ave a logic error in my planings ?
i thought if the 3.3v pulse from the remote came to the "record" button the same happend as i press the button manualy.

excuse my bad english and i hope i find some help here

ps:
is there a way to use the short 3.3v pulse to control the lights on/off ?
lets say theres a component getting the 3.3v pulse and open a circuit to get power for the led's.
on next pulse he close the circuit to power off led's
