Counter-Surveillance Probe and Monitor

bobby leonard No Comment

The CPM-700 Counter-Surveillance Probe and Monitor is a broadband receiver that can detect and locate major types of electronic surveillance devices including room, telephone, body bugs, video transmitters, and some tape recorders. A basic Counter-Surveillance Probe and Monitor sweep kit with its custom Cordura case contains all of the items necessary to conduct a low threat sweep. The CPM-700 provides a very important cost effective tool for professional sweep teams, government security personnel, and private citizens with important security needs.

This type of instrument is so useful on a sweep that each person on the detail should have at least one of these dedicated to them. In the event that only one piece of equipment can be brought along for the sweep; such as when on an EP team, then this is the one to have. This instrument is also ideal for a private investigator or security manager who needs a limited capacity to perform sweeps but is not able to bring in an outside TSCM specialist. The unit is also perfect for private individuals who wish to discretely perform their own sweeps or bug detection.

When the CPM700 is used along with the OSC-5000 and ORION NLJD the three instruments become invaluable in ferreting out even fairly sophisticated eavesdropping devices. Typically, every sweep team will have at least two of these systems on hand at all times, and will typically have one complete system for each person on a sweep team, or protective detail.
