  如何選擇合適的監控電源?
  How to choose the right monitoring power supply?
  1、監控攝像機標明DC12V/AC24V通用,該選擇什麽樣的電源?
  1. The monitoring camera indicates that DC12V / AC24V is universal. What kind of power supply should be selected?
  選擇AC24V監控電源,因為同樣的傳輸距離,電壓越高,損耗越小。電壓高了,負載就能得到比較充足的電壓。同時,由於采用交流24V,在調試監控攝像機的時候,可以選擇電源同步,使整個監控係統中不同的設備的圖像場頻能夠保持同步。
  Select AC24 V monitoring power supply, because the same transmission distance, the higher the voltage, the smaller the loss. When the voltage is high, the load can get enough voltage. At the same time, due to the use of AC 24 V, when debugging the monitoring camera, you can choose the power synchronization, so that the image field frequency of different equipment in the whole monitoring system can be synchronized.
  2、如何合理配置整個監控係統的監控攝像機浙大中控電源功率?
  2. How to reasonably configure the power supply of the central control system of Zhejiang University?
  這個問題經常讓年輕沒有經驗的工程師為難,很多方案在實施的時候都發現當初設計的電源容量不夠,需要追加設備,造成和甲方扯皮現象。實際上,由於監控攝像機在啟動瞬間,啟動電流很大,再加上工程上遠距離傳輸的損耗,所以,監控攝像機需要的電源,不是簡單地把所有監控攝像機的額定功率相加。正確的做法是把整個監控係統的監控攝像機的額定功率相加再乘以1.3倍,這個是監控攝像機實際需要的功率,然後再加上約30的損耗;然後再加上30的餘量,作為將來擴容使用。
  This problem often embarrasses young and inexperienced engineers. During the implementation of many schemes, it is found that the power capacity originally designed is not enough, and additional equipment is needed, resulting in disputes with Party A. In fact, since the starting current of the surveillance camera is very large at the moment of starting, and the loss of long-distance transmission in engineering, the power supply required by the monitoring camera is not simply adding up the rated power of all surveillance cameras. The correct way is to add up the rated power of the monitoring camera of the whole monitoring system and multiply it by 1.3 times, which is the actual power required by the monitoring camera, and then add about 30 loss; then add 30 surplus for future expansion.

  3、監控攝像機浙大中控電源的配置,比較忌諱的是什麽?
  3. What is taboo about the configuration of central control power supply for surveillance camera in Zhejiang University?
  忌諱的是:整個監控係統共用一個電源。原因如下:
  Taboo is: the whole monitoring system shares a power supply. The reasons are as follows:
  1)係統維修的時候,經常需要打開、關閉電源。所有的監控攝像機在打開電源瞬間同時啟動,啟動電流特別大,對電源的衝擊力很大,嚴重的會燒毀電源,2)所有的監控攝像機共用一台電源,當電源發生故障時,整個閉路監控係統陷入癱瘓。尤其是一些重要出入口的圖像無法監視,可能會造成不必要的麻煩。
  1) When maintaining the system, it is often necessary to turn on and turn off the power supply. All the surveillance cameras start at the same time when the power is turned on, and the starting current is especially large, which will have a great impact on the power supply, which will burn down the power supply seriously. 2) all the surveillance cameras share one power supply. When the power supply fails, the whole closed-circuit monitoring system will be paralyzed. In particular, the images of some important entrances and exits cannot be monitored, which may cause unnecessary trouble.
  那麽正確的做法應該是怎樣呢?如上麵例子,一個商務樓有100台固定監控攝像機,總共需要約800W的電源,正確的配置應該是選擇4台、每台200W的電源。這樣,當某一台電源發生故障,可以把重要出入口的監控攝像機接到其它好的電源上,不至於影響整個係統的工作。
  So what is the right way to do it? For example, a business building has 100 fixed surveillance cameras, which requires a total power supply of about 800W. The correct configuration should be to select 4 sets of 200 W power supply for each. In this way, when a certain power supply fails, the monitoring camera at the important entrance and exit can be connected to other good power supply, which will not affect the work of the whole system.
  4、監控攝像機電源的選擇還需要注意什麽問題?
  4. What problems should be paid attention to when choosing the power supply of the surveillance camera?
  一:在給監控攝像機接電源時,不要把距離較遠的監控攝像機和距離較近的監控攝像機接在同一台電源上。如果接在同一台電源上,電源電壓高了,會燒毀近距離的監控攝像機,電源電源低了,距離較遠的監控攝像機無圖像。應該盡量把距離比較遠的監控攝像機接在同一台電源上,把較近的監控攝像機也接在同一台電源上。
  1: When connecting power to the surveillance camera, do not connect the remote surveillance camera and the closer surveillance camera to the same power supply. If it is connected to the same power supply, if the power supply voltage is high, the close-up monitoring camera will be burned. If the power supply is low, the remote monitoring camera will have no image. We should try our best to connect the remote surveillance camera to the same power supply, and connect the closer surveillance camera to the same power supply.
  二:如果監控距離太遠,需要配置更高電壓的電源,如30V,36V等等,甚至直接供220V交流電,到前端再變壓。
  2: If the monitoring distance is too far, it is necessary to configure a higher voltage power supply, such as 30V, 36V, etc., and even directly supply 220 V AC, and then change the voltage to the front end.
