Private Detective – Surveillance

Surveillance is a very useful tool. However, there are initially cheaper options available to you before you commence long periods of surveillance. Man hours are expensive and there are other more cost effective methods you can try first.

Physical surveillance is difficult and needs to be carried out by a Professional Company who have the experience to do this correctly and covertly.
