Infra Red bathroom mirrors. 150mm, really?

[Melchett]

I am after one of those bathroom mirrors that can be turned on by waving your hand about, this one actually:

http://www.modernhomesbathrooms.co.uk/mirrors-cabi...

But, there is note saying: 'All mirrors featuring infrared technology must be mounted a minimum of 150mm from an adjacent wall or obstruction to ensure correct function of the infrared sensor.'

I know they usually say this for a reason, but does anyone know if you can get away with less? Im looking at 100mm away from the shower glass. Thats the best I can do.

Or, if anyone has something like this, are there sensors on both sides? Could I get away with covering the sensor that is close to the glass and just use the one on the other side?

Any help and advice much apprecciated.
