We use signal detection equipment (7 types) to detect and locate possible eavesdroppers; we use physical detection equipment (4 types) to conduct rigorous investigations on the working principles of different eavesdroppers; including professional vehicle detection equipment (7 types), in addition to detection equipment and means, we provide protective equipment (11 types) that can be selected according to needs. Through rigorous detection and protective measures, we ensure anti-theft detection in commercial institutions.

7 types of signal detection equipment：Through the cooperation of multiple devices, the detection area can be covered more comprehensively, and the accuracy and efficiency of eavesdropping investigation can be improved. In practical applications, the use of these devices should be reasonably selected and configured according to specific circumstances to maximize their detection effect.

4 types of physical detection equipment：Based on the working principles of different eavesdroppers, physical detection equipment is used for rigorous investigations. These physical detection equipment include BOX-RC02 wall line detection equipment, BOX-GXJC01 optical eavesdropping detection system, etc. These devices use infrared and other principles to detect eavesdroppers that are particularly concealed.

7 types of vehicle theft detection：For official vehicles and other means of transportation, we will conduct anti-positioning tracking detection, using GPS detection equipment, signal source search locator, frequency searcher, privacy guard, undercarriage inspection mirror and other detection accessories (electromagnetic shielding tent, strong light flashlight, car clothing rack) and other equipment to check the locator and illegal eavesdropping equipment inside and outside the vehicle.

Signal detection equipment annotation：Continuous electromagnetic environment monitoring can detect the existence and strength of these radio signals, timely discover new wireless signal sources, and help identify and locate suspicious illegal monitoring or surveillance equipment.

Physical detection equipment annotation：For example, infrared detection equipment can detect infrared radiation to detect eavesdropping equipment. Some eavesdropping devices emit infrared radiation when working. Therefore, by detecting infrared radiation, potential eavesdropping devices can be found, and there are also physical detection equipment such as optical eavesdropping detection systems.

Vehicle detection equipment notes：For example, the electromagnetic shielding tent used in vehicle theft detection is mainly used to block and reduce interference signals outside the small vehicle, while preventing the signal inside the vehicle from transmitting data outside, forcing the suspicious positioning device to connect to the signal detection (adsorption) device and cooperate with other equipment to complete the detection.
