My Samsung intercom/doorphone unit at the front gate is housed in a surface metal box.
Dimensions: 12 x 15 x 4 Centimeters (80% empty space inside)
During the winter period it is prone to occasional ring of it's own accord (Usually at some godforaken hour).
I'm 98% sure that it's being caused condensation/moisture.
I'm going to run an extra pair of wires into the housing and fit some type of heating element.
I have a bunch of DC transformers available to me (Up to 12v - 2 Amps)
I'm looking for suggestions as to Voltage/Current and the heating element.
(An old car filament bulb or a wirewound resistor was what initially occured to me)
