Eighty Butler's Little Wife (MTL)

Chapter 76

    After listening to Li Jinyu, she didn’t take it seriously. She had already seen a demonstration by comrades in the public security department. This infrared sensor is really amazing. As long as the area swept by the sensor is touched, the alarm will sound immediately. It is a centimeter away. You can perceive something approaching, and you install this to prevent thieves from stealing, not to mention that people can't escape detection, even small animals will come in, and the sensitivity is super strong.

    Half a year ago, their home was stolen by a thief, and their income for a whole year was stolen by the other party, and it was all hard-earned money. After this loss, the family was almost unable to live on. The money for medical treatment was borrowed by relatives. The life was very difficult, but since then, the awareness of prevention has strengthened and paid great attention to this aspect.

    So Li Jinyu feels that buying an alarm is a very worthwhile thing, and the alarm is only a few dollars, and you can prevent theft as much as possible when you buy it. It is better to get a painful lesson than something happened.

    So in terms of anti-theft, it doesn't hurt to spend more money.

    In particular, Li Jinyu felt that the money was bought for anti-theft and wanted to fall into the hands of the thief. As for hearing the yin and yang of other people’s ridicule, he didn’t take it seriously. If the thief had to keep an eye on her house, this time it would be fine to step up prevention. Test the effect of this anti-theft device.

    Her house has been stolen, and now there is nothing of value. The whole house is empty. After the thief comes, she can only go for nothing. But if the theft is frequent, her neighbors should be more worried. .

    Li Jinyu shook his head and said, "Old Sister Wang, there is nothing to steal if the thief comes to my house again. It happened to take revenge on what happened last time. After such a long time, I don’t want to be able to recover the loss. I just don’t want this thief to get away with it. It’s really hateful.”

    Sister Wang said she didn’t believe it at all. I even laughed: "You said this thing can catch a thief? That's ridiculous, isn't it so easy to catch a thief? These days, thieves are smarter than monkeys, and you can be called a thief if you catch it. Oh, how much did you spend on this thing, it doesn’t look very good at all."

    The infrared sensor that Li Jinyu holds in his hand is a small plastic box and a few small light bulbs the size of soybean grains. It is not worth a few cents at first glance. It has no reliability at all. How could it be possible to catch a thief? She must have deceived people, and returned the money to the victim.

    Li Jinyu wanted to rectify the name of the alarm and said: "I bought this set for ten yuan, and I bought three sets for a total of thirty yuan. Don’t be small, it’s really useful. The temperature can't escape its induction."

    Old Sister Wang heard it even more terribly: "Buy it for ten yuan each? There is nowhere to spend more money. I don't know if you are stupid or stupid, with the money. Just buy useless things. I don’t think you are short of money."

    Li Jinyu waved his hand: "If you don’t believe me, there is no way to explain this matter. Anyway, I believe it can be safe."

    "Hey, I see you. It’s a waste of time.”

    After Sister Wang finished speaking, other onlookers also talked about it, all of them were not optimistic that this thing could prevent theft. It was really because the appearance was a bit shabby and it didn’t look like high-tech. As for what temperature should be used. Induction is a technology that has never been heard before.
