I have ordered this level shifter from banggood.

I plan to hook my DSC-PC1550 to

I asked if the level shifter can do 12V to 3.3V and they said it can't. It appears to be the same as the ones linked. Can anyone confirm if this will work?
If not I have found another circuit that uses a 10K resistor and a BC547, but it would not be bi-directional I don't think.
Thanks
