Network cameras are useful to installed in small area.
For the monitoring of a large network environment, the emergence of wireless networks can save the most wired worry. However, the erection of the wireless network but also bring about a more troublesome problem. For example, the reporting frequency and the signal interference. Of course, this is for a large corporate or municipal needs may not be anything too complex problem. So, today we are mainly introduced to monitor, how to be able to better the management and installation of the camera under limited conditions, in the low frequency range.
Any transfer tool can not guarantee for the Wi-Fi signal strength constant, the attenuation of the signal is the main problem we have to face. Further, since the country also has a strict limitation for the signal transmission distance. Therefore, it can be said that the use of their own frequency transmission is not an easy thing. Especially close and public frequency signal by the impact will be more obvious. So, when we build the system, but also, as far as possible, avoid using closer to the frequency of use and the public signal (4.9GHZ).
For wireless monitoring system, on the other hand, the impact of the obstacle can be said to be a very important issue. Since the majority of the radio frequencies are concentrated between 2.4GHz to 5.8FHZ,. This frequency is also the most vulnerable to our ordinary buildings or objects affect the band. Therefore, in some object or distances greater than 100 meters from the monitored environment, the a simple wireless band transmission may be difficult to achieve the normal transmission of the signal, which also requires a number of the mesh structure of the network to avoid the network transmission of interfering objects. Of course, this is bound to cause some cost increments.
