Unconventional operations that often occur in video surveillance systems

The unconventional operation video surveillance system that often appears in the video surveillance system is very simple for some old drivers, but it seems simple to some novices, and it is not simple. Today, Xue Ge will focus on several kinds of very important things that appear in video surveillance. You may also encounter regular operations. If you do, here is your solution. At present, the mainstream solution of video surveillance system is POE power supply and power adapter power supply. The POE power supply mode occupies more than half of the market. Because the wiring is simple, the maintenance is convenient. 1. What is the conventional POE-powered video surveillance system like? Case 1: POE camera + POE switch + fiber optic transceiver + fiber optic transceiver + core or aggregation switch + hard disk video recorder + display device Case 2: POE camera + POE switch + optical module + optical module + core or aggregation switch + hard disk video recorder + Display equipment 2. What is the video surveillance system powered by a conventional power adapter? Case 1: Camera + switch + optical fiber transceiver + optical fiber transceiver + core or aggregation switch + hard disk video recorder + display device Case 2: camera + switch + optical module + optical module + core or aggregation switch + hard disk video recorder + display device What about the unconventional POE power supply video surveillance system? Case 1: POE camera + POE powered hard disk video recorder + display device Case 2: Camera + POE splitter + POE switch + optical fiber transceiver + optical fiber transceiver + core or aggregation switch + hard disk video recorder + display device Case 3: Camera + POE separation + POE switch + optical module + optical module + core or aggregation switch + hard disk video recorder + display device Case 4: POE camera + POE power supply module + switch + optical fiber transceiver + optical fiber transceiver + core or aggregation switch + hard disk video recorder + display Equipment situation 5: POE camera + POE power supply module + switch + optical module + optical module + core or aggregation switch + hard disk video recorder + display device The above are common wired network networking methods in video surveillance. Fourth, the above three methods are described below Analysis of the video surveillance system of the conventional power supply is not discussed. Everyone does it in accordance with this operation. For the video surveillance system with unconventional POE power supply, we may encounter the following situations when we do a project for the first time in reality: 1. What should we do when we purchase non-POE cameras and POE switches and the cameras cannot be exchanged? Answer: Increase purchase of POE splitter, standard 48V. 2. What should I do when I purchase non-POE cameras and POE hard disk recorders, and the cameras cannot be exchanged? Answer: Increase the purchase of POE separators, as for what kind? This depends on whose POE hard disk video recorder you use, the above standard 48VPOE splitter may not be applicable, remember! For example, if you have both of these two situations in one project, you have purchased the above standard 48VPOE splitter. As a result, adding a POE splitter to the POE hard disk video recorder will not work. This situation is embarrassing. V. Discuss the cost analysis of the above situation. The price of POE cameras and non-POE cameras is not much different? The cost of adding a POE splitter or a POE power supply module must be greater than the price difference between a POE camera and a non-POE camera. In addition, the risks involved are greater, such as after-sales service, system stability, and replacement costs for damage to the POE splitter and POE power supply module. 6. Methods to prevent this kind of phenomenon from happening How to prevent this kind of phenomenon from happening? It is very simple. The preliminary design must be in place. If the preliminary design is not in place, the later design will be deepened and the construction plan must be carefully optimized. No longer, pay attention to purchase!
