"I am very grateful to you for the work you did for us last month. Thanks to your hidden camera, we were able to finally prove that we had a thief amongst the auxiliary staff and, because we had hard evidence, his boss relieved him of his duties. I appreciated your prompt attention to my inquiry and your professionalism in installing the system." Janet
"I had a great experience with Phase4! I live out of state and needed a court order on a local resident. They took all of my worries away and went above and beyond what I could have ever expected a company to do. I can't recommend them enough!" Amie
