Jan 30 (Reuters) - Home security services company ADT Corp reported a higher quarterly profit on Wednesday and announced a $600 million accelerated share repurchase.

The company, formerly a part of Tyco, said net earnings had risen 12.9 percent to $105 million, or 44 cents per share, from $93 million, or 39 cents per share, a year earlier.
