Going unnoticed is important when handling a case and is one of the reasons our San Dimas investigators do not live in the area.

If a case lasts for just a few days or several months our professional San Dimas private investigators are capable of making certain that it is properly documented and put together to ensure it cannot be refuted, even by the best opposing attorney. In fact, we have developed relationships with San Dimas attorneys, many who know they can call on us anytime to put together the missing facts necessary to win a case.
Some of the technology we use in our surveillance are video cameras, still photo cameras, unmanned cameras, radio communication systems, motion detection cameras, and unmanned aerial surveillance. With our firm you have access to any technology necessary to make certain your needs are met.



While we make unmanned aerial surveillance available, most situations do not require such extreme measures, yet they do require long term monitoring, which in itself can eventually become costly. This is why we have perfected our use of unmanned cameras; with unmanned cameras, we can oftentimes surveil an area for 7-10 days for the same cost as a single day of manned surveillance. This use of technology makes it possible for us to build a case while at the same time remaining an affordable service.
