Angular JS naming conventions ($, camelCase and PascalCase)

What is the convention in AngularJS for prefixing providers with $? Should I prefix all custom services in my own code?

We can filter Text in CamelCase using following code 
 app.filter('camelCase', function(){
            var camelCaseFilter = function(input){
                    var words = input.split(' ');
                     for (var i = 0, len = words.length; i < len; i++)
                         words[i] = words[i].charAt( 0 ).toUpperCase() + words[i].slice(1);
                     return words.join(' ');
                 };
                 return camelCaseFilter;
        });
