What is considered, “state of the art” today, becomes “old school” tomorrow. That’s why Gary Glanz & Associates strives to stay on the ever changing, cutting edge of gee- whiz technology and investigative resources. While we can’t reveal our secret gadgetry, without upsetting agent Q, we can show you some of the once cutting edge tools, used by Gary Glanz, to help solve some of Oklahoma’s most interesting capers, cons and conundrums.



Vehicle Tracking


Before the days of pinpoint accurate, lithium-ion powered GPS trackers, that can be viewed from your tablet sized smart phone, there were Bumper Beepers. Using a Bumper Beeper to run a surveillance was a lot like playing a two person game of Marco Polo in an overcrowded, public swimming pool.

In this polaroid photo, Gary Glanz demonstrates the installation of, a now retired, vehicle tracking wonder. This magical device worked by paring a set of nine volt batteries with a simple radio transmitter, and a magnetic mount. Once powered on, a feat accomplished by flipping the switch, and enjoying the satisfying “click” that only a mechanical ON/OFF switch can give, the device would begin broadcasting a steady radio “beep”. This “beep”, could be picked up by a special radio in the investigators vehicle, and based on whether the sounds was getting louder or softer, the investigator could determine if the vehicle was getting closer or farther away.


Video & Photography


Those who have undergone a Colonoscopy can certainly appreciate the miniaturization of video camera technology. While it’s true that cameras today have gotten so diminutive that they pose a choking hazard to small children, things haven’t always been that way. In this photo Gary Glanz is seen using a hefty telephoto lens, mounted to a 35mm film camera; a combination which weights only slightly less than a runway model.

Before the days of high definition pinhole cameras and thermal imaging, Gary Glanz got the shot by hiding 35mm cameras behind one-way mirrors, or poking motorized 17mm video cameras out of air conditioner vents. Of course all of this was done before the days of Instagram filters, so the big magic happened in the dark room, where the photographs and video came out with that natural, sepia toned, soft vignette, that people on Instagram fawn over.
