Flame Retardant Magnesium Hydroxide
Flame Retardant Magnesium Hydroxide
Magnesium hydroxide is a new type of filled flame retardant, which can reduce the surface temperature of the filled synthetic material in the flame by releasing binding water and absorbing a large amount of latent heat during thermal decomposition. It can inhibit the decomposition of polymers and cool the combustible gas produced. The use of magnesium hydroxide flame retardant also brings convenience to people.

You can find some digital wireless bridges. If your laboratory building is relatively high, you can install the wireless bridge on the roof as the receiving end, and use the omnidirectional antenna to do a point-to-multipoint transmission mode to receive transmissions from all sides. Monitoring video signal. At present, domestic brands that do a good job of doing wireless bridges are known to me as Tengyuan Zhituo, Lian Technology, and Huawei. Can find out information in other channels.
Are you asking about wireless transmission equipment for wireless surveillance in school? The so-called wireless monitoring is nothing more than a combination of surveillance camera + wireless transmission equipment. The buddy upstairs also said, you can use the wireless bridge to do the transmission, the domestic number of brands to do wireless bridges to count the number is so few, which Teng Yuan Chi extension's price is still quite high, and other I am not very clear.
What kind of wireless monitoring equipment is used for school monitoring?
Our colleague and his children’s school has a total of seven buildings including a teaching building, an experimental building, a dormitory, and a canteen, and now they want to install a high-definition webcam on the stairwell of each building. Finally, all surveillance videos are sent back to the laboratory building. Room monitoring room, if you want to use wireless monitoring, what transmission equipment should be better?
