Surveillance refers to a close observation of a person or group to monitor their activities to gather evidence and meet the objectives of the case. Surveillance is difficult and takes years of practical application in order to be effective. It is never recommended that someone other than licensed private investigators perform surveillance as most states have laws preventing it (stalking and Harassment).
