tapping a nail and electric wires

I would like to hang a picture on the wall but I remember that near that area there used to be an intercome. It was removed and the wall replastered. I can't be 100% sure that the wires are not live. Furthermore, 40 cm from the potential nail position there is a thermostat. Is there any way to easily check and do things safely? Or I'd better hang the pictures somewhere else? Thanks.

That is why stud finders were invented, wiring is attached to the sides, your nails would presumably go into the center or away from them all together, but you need to know where they are!

You normally would use one or two of these. The nails are short and don't penetrate the wall far enough to hit any wires. And if the picture is large, put 2 of these on the back (sides) of the frame.

Thanks, I thought so. Better buy or borrow a stud finder then. The wires of the intercom are near the 'surface'. Same as for light switch, isn't it? Pardon my electrical vocabularly.

By code, wires in walls should be no closer than 1 3/4" from the wall surface except directly behind the fixture where they come out to it. If the intercom was removed, the wires were likely stuffed back into the wall when it was repaired. IMO you are worried about nothing.
