Invisible anti-theft net material
The invisible anti-theft net is made of stainless steel wire with the thickness of 1.5mm-3.0mm, which is tightly wound between alloy bases. The steel wire is 304/ 12+ 1 copper conductor steel wire, and the copper conductor is insulated from the outer steel wire layer. The steel wire spacing is fixed at 5cm, and the steel wire can withstand 1 10-65438.
Invisible anti-theft net alarm system
1, adopts American original computer chip, CPU microprocessor, adaptive digital intelligent modulation and multiple infrared gratings to form an invisible defense line, which does not affect the normal activities of people outside the defense line at ordinary times, with leading technology and excellent performance;
2.3 gear protection distance is adjustable, and AGC circuit is designed with high sensitivity;
3, anti-disassembly, anti-shearing, anti-movement, and the principle of double-beam identification can effectively prevent false positives caused by small animals, birds and other small objects;
4. Adopt special optical technology and imported filter, which has strong anti-interference ability and high reliability, can effectively suppress stray light and sunlight, and the false alarm rate is extremely low.
Is the invisible anti-theft net safe?
Advantages:
1, beautiful. 2mm steel wire rope, after installation, does not affect the external wall, which is consistent with the original architectural style and meets the requirements of the current urban building facade. /kloc-basically invisible beyond 0/5 meters, and does not affect the field of vision.
2. Safety. Each steel wire can bear the gravity above 85- 120KG, and the spacing between steel wires is small (5 cm spacing), which can effectively protect children's safety and prevent them from falling when climbing.
3, anti-theft. This product is specially designed with wire cutting alarm function. When the thief cuts the steel wire, the intelligent alarm connected with the steel wire will send out an alarm signal. There are two ways to give an alarm: voice alarm (when giving an alarm, it will give out a sharp cry of 120 dB) and alarm host will automatically start dialing alarm function (dialing seven preset numbers continuously).
4. Easy to escape. Of course, when there is a fire, adults only need to clamp it in a vise for a few seconds, then they can cut it open and escape quickly. Firefighters can enter from the window, which can save first aid time.
Disadvantages:
It requires high installation quality, and improper installation will leave potential safety hazards. For example, a large area of anti-theft net installation must have a solid wall.
How to choose the invisible anti-theft net?
Steel wire is the factor that determines the safety of the stealth anti-theft net, and the factors that affect the quality of the steel wire of the stealth anti-theft net are the material of the steel wire and the machining accuracy of the steel wire. At present, the steel wire with the best corrosion resistance on the market is 3 16 stainless steel wire, followed by 304 stainless steel wire, and the service life of the invisible protective net of these two kinds of steel wires can reach 20 years; At present, some low-priced steel wires on the market are mostly 302 stainless steel, 202 stainless steel or high-precision steel. The service life of this kind of steel wire invisible protective net is less than two years, and some even begin to rust in less than half a year. Experts believe that only 3 16 or 304 stainless steel wire can be used as an invisible anti-theft net.
However, the material of steel wire and some technical indicators are difficult for us to distinguish with the naked eye, and the irresponsible false promises of some merchants make us feel at a loss. Therefore, we should pay attention to the following points when distinguishing:
1, check whether there is a test report from a national authority. From the report, we can distinguish the material and related indicators of steel wire, and some businesses that use inferior materials basically have no test reports.
2. Check whether the product is underwritten by the insurance company.
3. Multiple comparisons and patient selection. As the saying goes, there is no discrimination without comparison. By comparing different businesses, we can get to know them through their offices and talking with people.

Generally speaking, the price of stealth anti-theft net is very clear, and there is no obvious price difference in the region. If you want to specifically ask how much the invisible anti-theft net costs, this can't give you a definite answer, because it is related to the size of the installation area and the degree of danger of installation. Only when you choose the steel wire and materials can you know how much it costs to install the invisible anti-theft net. Generally speaking, the price of stealth anti-theft net fluctuates between 90- 120 yuan/square meter.
The quality of doors and windows directly affects the safety of home life. Although the invisible anti-theft net is beautifully designed, experts suggest that the steel anti-theft net is the safest in the choice of anti-theft net.
