At Gary Cox Investigations we have the experience, integrity and all the necessary skills to undertake personal investigations in a discreet and professional way. We treat the information you entrust to us with the utmost respect and confidentiality. Our surveillance operatives have the skills to follow without being detected and film activities without being seen. It is what they do day in and day out. The key to all surveillance operations is discretion. Being discreet as we go about our investigations is of the utmost importance.
