Chapter 254: Detection Equipment
Zhou Yuan and Chu Xiaolu stood on the side of the road. Zhou Yuan waved to the oncoming vehicles. A taxi that was empty stopped beside them. Zhou Yuan opened the back door and let Chu Xiaolu get in first. Then he got into the back seat and closed the door.
"Sir, where are you going?"
"Go to Longcheng Square."
"it is good."
The driver accelerated the car and quickly left the west gate of the community. After about twenty minutes, the car arrived at Longcheng Square.
Longcheng Square is a bustling area in Huasheng Special Zone, offering everything from food and drinks to entertainment and shopping.
Chu Xiaolu saw an ATM next to a shopping mall, so the two went in. Chu Xiaolu inserted her bank card, looked at the PIN on the attached paper, entered the PIN, and was stunned to see that the balance was two million. Chu Xiaolu withdrew 50,000 in cash, and the two left.
Zhou Yuan and Chu Xiaolu arrived at the fourth floor of a large shopping mall, in the clothing and footwear section. They bought three sets of clothes and shoes, changing out of everything they were wearing, including their underwear, without even considering that the new clothes needed to be washed before wearing. Even Chu Xiaolu's own handbag was replaced with a new one.
When it was time to pay, Chu Xiaolu paid in cash. The two of them stored their two newly bought sets of clothes, shoes and socks, the clothes, shoes and socks they had changed out of, their handbags, along with their mobile phones and batteries, in the mall locker.
After changing all their belongings, the two went to the sixth floor of the mall and bought three new mobile phones and SIM cards. After testing each other's calls and confirming that they were clear and easy to answer, they thanked each other and left.
After the two walked out of the mall, they felt a sense of relief and smiled at each other.
"Honey, where are we going now?" Chu Xiaolu asked Zhou Yuan softly, linking her arm with his.
"Let's browse other shopping malls and see if they have any bug detection devices. Also, I need to build a shortwave radio, so I need to buy components, power supplies, tuning kits, antennas, and other modules."
"Shortwave radio stations, using skywave propagation?"
"um, yes."
"But if we use skywave transmission, the signal will be very unstable, right? There are too many factors that affect the signal, and the signal attenuation will be severe."
"Baby, don't worry, I have a way to solve this." Zhou Yuan kissed Chu Xiaolu on the cheek, and Chu Xiaolu kissed Zhou Yuan on the cheek in return. Now the two really looked like a married couple.
Zhou Yuan and Chu Xiaolu strolled hand in hand through other shopping malls, carefully searching for shops that sold eavesdropping device detectors, but there were no such detectors or wireless transceiver equipment in Longcheng Plaza.
After consulting with a shopping mall security guard, the two took a taxi to eWorld, a large electronics mall nine kilometers away from Longcheng Square.
The large electronics mall eWorld seems to occupy an area even larger than Longcheng Square, and it has all kinds of electronic products and devices.
Following the mall's signs, Zhou Yuan and Chu Xiaolu arrived at Block C of Section B, which housed the listening and surveillance equipment area. As soon as they entered Block C, they found a diverse group of people, all consulting at various counters.
Zhou Yuan glanced around carefully and saw a sign that said "military." He then pulled Chu Xiaolu over to the sign. The shop owner saw the two of them approaching and said, "Sir, would you like some listening and surveillance equipment? We sell military-grade equipment."
Zhou Yuan leaned forward and asked the shop owner in a low voice, "Boss, do you have military-grade eavesdropping device detectors and pinhole camera detection equipment?"
The boss glanced at Zhou Yuan and Chu Xiaolu, but didn't say anything; he just nodded slightly.
"Sir, this product is a little pricey," the shopkeeper said softly.
"I need the best performance; we can discuss the price."
How many do you want?
"Two."
"Sir, please wait a moment." After saying this, the boss walked to the table on the wall and started dialing a landline. He whispered something that Zhou Yuan and Chu Xiaolu couldn't hear.
Seven or eight minutes later, a young man came over with two boxes, handed them to the owner, and left.
"Sir, please take a look." The shopkeeper handed a box to Zhou Yuan. Zhou Yuan glanced at the label on the box, first checking the performance specifications. He noticed a line of inconspicuous text at the bottom of the box indicating it was military-grade. The product's applications included detecting hidden wireless earphones, wireless pinhole cameras, mobile phone eavesdropping devices, wireless listening devices, wireless pinhole cameras, watch cameras, and GPS trackers. It had two detection modes: laser detection and wireless frequency scanning. The wireless frequency scanning detection frequency range could reach 50MHz-10GHz.
"Boss, can I open it and take a look?"
"can."
Zhou Yuan slowly opened the two boxes. From the outside, the two devices looked exactly the same. Zhou Yuan held one of the devices, which was just big enough to hold in his hand. The lower part was a rectangular LED display screen, and the middle part resembled a circular alarm clock. The central area of the alarm clock was a transparent glass lens (window/wired detection lens), and the edge area of the alarm clock was a digital display dial showing the signal strength. In the upper left corner of the alarm clock, there was a "tentacle," which was a retractable metal antenna.
On the left side of the handheld detection device are a charging port, signal indicator light, LED laser switch, and speaker/buzzer. On the right side are an LED laser light, signal sensitivity adjustment button, charging indicator light, power switch, and mode switch. There are three automatic detection alarm prompts: sound alarm, vibration alarm, and LED light alarm.
Chu Xiaolu also came over to take a closer look and nodded.
"Boss, can we try it and see if it works?"
"Okay, wait a moment." After saying that, the boss squatted down, took out a few items from the cabinet, and then quickly set up listening devices and pinhole cameras on the counter, walls and other places.
"Sir, why don't you give it a try?"
Zhou Yuan turned on the power to a handheld detection device, and suddenly a buzzing vibration sound came out, while the LED indicator light flashed continuously.
Zhou Yuan moved his handheld device away from the counter and walked a bit further away. The sound became weaker. Zhou Yuan extended the antenna, and the sound returned. Zhou Yuan walked for more than twenty meters before the vibration disappeared and the LED light stopped flashing. Zhou Yuan then turned back and walked towards the counter. The vibration intensified, and the LED indicator started flashing incessantly again.
Zhou Yuan walked the handheld device back and forth by the counter. There were obvious differences in the intensity of the buzzing vibration and the signal display. Zhou Yuan handed the handheld detection device to the boss, who brought it close to a bugging device. The sound and vibration were very strong. The boss turned on the sound switch, and the handheld detection device suddenly emitted a rapid, piercing beeping sound. The boss then turned the sound off.
"Sir, next I will demonstrate how to detect pinholes or wireless cameras." The boss turned on the LED laser switch, the LED laser lights lit up, and the 6 LEDs on the back of the detection device began to flash. The boss moved the detection device up, down, left, and right to perform a laser scan of the surrounding environment. The boss's eyes observed through the host window, and when he encountered a camera in front, he would see a very bright spot flashing (with vibration and sound prompts).
The shop owner installed a pinhole camera in a gap outside the counter and gestured for Zhou Yuan to try it out himself. After a while, Zhou Yuan figured out how to detect pinhole or wireless cameras.
Zhou Yuan walked over to Chu Xiaolu, asked her for the phones they had bought, put the battery and SIM card in one of the phones, and handed it to the shopkeeper. The shopkeeper understood, took the phone from Zhou Yuan, turned it off, opened the phone cover, took a small button-like object from a corner of the counter, put it inside the phone, put in the battery, closed the phone cover, turned it on, and dialed his landline. The handheld detection device in Zhou Yuan's hand started vibrating again.
Zhou Yuan nodded to the boss, who turned off his phone, opened the phone case, removed the phone battery, took out a button-like object, put in the phone battery, closed the case, and handed the phone to Zhou Yuan.
Zhou Yuan then took another box containing a handheld detection device and personally tested all its functions.
Finally, Zhou Yuan, grinning, took the handheld device and probed Chu Xiaolu, finding nothing amiss. Chu Xiaolu then snatched the device from Zhou Yuan and, also grinning, probed him as well.
After asking the shop owner about the price, Zhou Yuan made a slight negotiation and the deal was finalized, with Chu Xiaolu paying in cash.
Zhou Yuan held the cardboard bag containing the two handheld detection devices. The two men were excited and couldn't wait to get home and start the detection immediately. But Zhou Yuan didn't plan to do that. Things needed to be handled slowly; acting too quickly would arouse suspicion.
Zhou Yuan and Chu Xiaolu then went to another building about ten meters away. This building was the radio station area.
An hour later, Zhou Yuan came out carrying a large suitcase, while Chu Xiaolu carried a small suitcase and a large bag. The two hailed a taxi and went to Longcheng Square first. Chu Xiaolu got out of the taxi to retrieve her belongings from the mall, and then returned to the waiting taxi.
When the taxi arrived at the west gate of the community, it was almost noon. By the time the two of them carried their belongings into the house, they were covered in sweat, their clothes soaked through.
Chu Xiaolu took the sheets out of the washing machine and aired them out. Then she put some newly bought clothes and socks into the washing machine to wash. She washed the faded clothes separately by hand and then spun them dry in the washing machine.
Zhou Yuan then took out a handheld detector and first checked the washroom and various toilets for listening devices. He then used an LED laser to check for pinholes or wireless cameras. To be on the safe side, Zhou Yuan used another detection device to check again, but found nothing unusual in the washroom and various toilets.
"Honey, let's take a shower first, then go out to eat."
"Okay." Chu Xiaolu finished hand-washing the clothes and was hanging them to dry on the balcony.
Zhou Yuan took out a set of clothes for men and women from the wardrobe, took them to the bathroom, and then used a handheld device to check them. Suddenly, the device emitted a buzzing vibration. Zhou Yuan took out his men's clothes, but the buzzing continued. Zhou Yuan put down the handheld device, picked up the women's skirt, and carefully touched it. He felt some abnormal protrusions at the waist belt, which felt hard. Zhou Yuan took away all the other clothes, leaving only the skirt in the bathroom. The buzzing of the device continued.
