The monitoring central control power supply is one of the indispensable power supplies in the current monitoring system. The monitoring central control power supply can be used not only on cameras but also on many electronic products. Central control power supply of Zhejiang University is also a kind of power supply that people prefer now. Because of the small size, light weight and high efficiency of the monitoring central control power supply.
Is it better to use switching power supply or central control power supply for the camera?
The selection of switching power supply and the monitoring of central control power supply are the same. Because there are many cameras, you can choose switching power supply because the power of switching power supply is relatively large and can support many cameras. If there are few cameras, you can choose to monitor the central control power supply because the power of the monitoring central control power supply is smaller than that of the switching power supply, and the prices of the two kinds of switching power supply are also different. The monitoring central control power supply is relatively cheap. So if there are few cameras, you can choose to monitor the central control power supply because it can reduce the company's expenses and save time.
How to reasonably configure the monitoring central control power supply in the monitoring system?
Because the power capacity of the monitoring central control power supply is not enough during the implementation of many schemes, it is necessary to increase the power supply, which leads to the phenomenon of wrangling. In fact, the instantaneous starting current of the camera is relatively large, and in addition, the project distance transmission is relatively easy to lose, so the power required by the camera is not enough. When calculating the power required by the camera, the rated power of the camera power supply must be added and multiplied by 1.3 times, which is the power required by the camera for monitoring and central control.
When selecting the monitoring central control power supply, you must remember that if the monitoring point is far away, you need to configure higher monitoring central control power supplies such as 30V and 36V. 220V AC monitoring central control power supply can also be selected. Because some cameras need different current, some need alternating current, and some need direct current. However, in general, the DC monitoring central control power supply is used. There are few AC monitoring central control power supplies.
In fact, there are many things to pay attention to when purchasing the monitoring central control power supply, but this should focus on how much power the camera needs to monitor the central control power supply, and what protection methods are available. Life problems will not occur unless a normal manufacturer is selected to monitor the central control power supply.
