What you are asking for is wrong very wrong, it is recommended IDs should be unqiue, but for learners sake here's what you would do

  var elem = document.getElementsByTagName("input");
  var names = [];
  for (var i = 0; i < elem.length; ++i) {
    if (typeof elem[i].attributes.id !== "undefined") {
      if (elem[i].attributes.id.value == "webcampics") {
        names.push(elem[i].value);
      }
    }
  }
  var webcamval = names;

Due to someone down voting after giving a full explanation why the above mentioned method is wrong, however does exactly what youve asked for, here's the correct method.

change all the inputs id to class

  var elem = document.getElementsByClassName("webcampics");
  var names = [];
  for (var i = 0; i < elem.length; ++i) {
    if (typeof elem[i].value !== "undefined") {
        names.push(elem[i].value);
      }
    }
  }
  var webcamval = names;
