The spectrum analyzing technology used in the PKI 4000 Counter Surveillance Sweeping System provides the professional level of sweeping. Giving full information about the radio frequencies being used in the area to the operator practically without necessity to move the equipment within the territory. The detection is comparative to the conventional RF detectors, so the sweeping procedure can be performed quickly and covertly, room by room.

This system can be placed both inside the room being checked and in an adjacent premise to provide secrecy of operation. 2-antenna analysis used in PKI 4000 allows you to detect RF bugging devices not depending on the type of modulation and encryption. Its working principle is based on the nature of radio waves to decrease power proportionally to the distance to the source. Signal on the close antenna will be stronger than the one received in the remote antenna. Such PKI system quickly selects the transmissions which originate from the inside of the premise.

The system has a built-in high-quality antenna switcher. After the sweeping the operator can perform the location procedure and find the exact location of the bug. In addition to the RF analysis PKI 4000 has the possibility to check the wire communications. Infrared range and electromagnetic range for presence of illegal signals. For this aim the system includes a low-frequency converter. The PKI 4000 system and its software have a simple intuitive interface and do not demand special knowledge from the operator. Typically the operation is performed in 3 stages:

Advantages of PKI 4000 Counter Surveillance Sweeping System:

1) Placement of the antenna or probes;
2) Pressing the corresponding operation button;
3) Watching the results.

At the same time professionals will find many highgrade possibilities and settings which can be useful for deeper learning of RF environment at a further usage.
