CAS No. of Ammonium Acetate is 631-61-8. The INS code is E264, it can be used in food additive as ph regulator (acidity regulator), buttfering agent, and can also be used as de-icing agent which can be biodegraded. It is a generally used chemical raw material in various industries.

In fact, the two networks A and B are connected through two wireless bridges with the same frequency. 
The adaptability of the three application modes of the wireless bridge
Lifting a wireless bridge will flash the concept of paired use in the brain. It is the use of point-to-point. In fact, during the use of the wireless bridge, in addition to point-to-point transmission, it can also be used in point-to-multipoint and relay mode. The following Lean technology introduced the difference between them.
1, point to point transmission
The application in the wireless monitoring industry is: if there are many cameras at the front end that can be transmitted together, the centralized cameras can be centralized by one switch, and then transmitted through one wireless bridge, and the receiving end can use one more. The same frequency bridge receives this signal. If there is only one network camera, directly connect the camera signal to the device with a network cable.
In this transmission mode, the loss is small and the transmission distance is long, which is suitable for no obstacles or long-distance transmission.
2, point-to-multipoint transmission
It is to establish the local area network by setting the wireless bridges to the same frequency as the network of points A and B and point C.
The application in the wireless monitoring industry is that the front end can transmit multiple bridges, and the receiving end receives a bridge.
This method is suitable for monitoring points or cameras more and more dispersed, although point-to-multipoint transmission, but the maximum limit, it is best not to exceed 1 to 4.
3, relay transmission
The relay mode is between A, B, and C. The signal of A is to be transmitted to C. The two points are blocked by C. However, if A and C are not blocked by B, you need to The signal at point A is transmitted to the relay point at point B, and then the signal is transmitted to point C through point B so that the signal at point A is transmitted to point C through relaying.
In wireless monitoring, if you want to transmit over the air in the case of an obstruction, you can only use relay mode.
This transmission mode does not have any effect on the effect of the transmission, but each relay will increase the delay slightly, so it is recommended not to relay too much in a wireless monitoring system.
The above three methods are more common wireless monitoring methods. Which one is adopted depends on the specific environment. If you are not very clear about the operation, you can tell the staff of Leian about the situation on the spot. We will give you the most suitable way.
