What are the ways to avoid the two major interference sources of wireless monitoring? Everybody knows that when it comes to wireless monitoring, another word that may make everyone think about it most easily is: interference. It is true that the convenience brought to us by wireless surveillance has become increasingly apparent, but at the same time, it has also deepened the fear of interference. In this way, “wireless monitoring†and “interference†have been tied together so innocently.
Whenever there is an unclear problem with our surveillance signals, we may all consider whether it is an interference problem. It is true that in our era of "wireless" today, it is not an easy task to completely get rid of interference, and external interference will affect our wireless transmission effects more or less. So how do we avoid interference?
Similar equipment interference
Avoid the interference of the same type of equipment in the surrounding area or the signal of the same equipment. The signal source of this interference signal may be a normal signal source in our system, and may be due to the same frequency or similar, resulting in the receiving terminal receiving no or receiving the same signal, making the receiving terminal difficult to identify. For this situation, we can adjust the frequency of the wireless device, select a clean channel, or change the position of the transmitter or receiver of the wireless device and pull the distance between the devices.
Construction disturbance
Buildings have a debilitating effect on the transmission of wireless signals. When a wireless signal passes through any object, its electrical signal will be refracted to a certain degree, causing its transmission direction to change, and it will cause reflection and attenuation of the signal. If you encounter a metal object in the transmission, it will increase the attenuation of the signal. Therefore, when selecting the installation position of the wireless device, the middle of the wireless device can be shielded as much as possible and visible from the middle of the transmitting end to the receiving end. This avoids the attenuation of microwave signals and the monitoring center can receive high-intensity wireless signals, thereby improving Monitor effect.
It is not a device that interferes with wireless, such as mobile, Unicom towers, walkie-talkies, wireless phones, etc. These have no effect on wireless microwave equipment. In the case of interference sources, we can adjust the frequency of the equipment or choose a location that is farther from the source of the interference. This will greatly reduce the interference to wireless microwave equipment.
