Nowadays PoE technology is widely used in network monitoring due to its highlights of simplify networking and reduce installation and maintenance cost. While, there are still some engineers don’t quite understand how it works. Here are 4 kinds of practical monitoring applications and solutions for your reference.
Solution 1: PoE Switch + PoE IP Camera
In this solution, users could connect the PoE switch with PoE IP camera directly through cable. But there are 4 tips for you:
Solution 2: PoE Switch + Non-PoE IP Camera
In this solution, users need to use a PoE splitter to get PoE switch and IP Camera connected. The PoE splitter would separate the networked PoE signal into power and data sources.
There are two output lines of PoE splitter, one line is for power output, the other one is for network signal of data output. The general output of voltage is 5/9/12V etc., which is matching with non-PoE powered devices of different DC input standard. Meanwhile, it is compatible with IEEE802.3af/at. Users can connect the data signal line with the Ethernet port of non-PoE IP camera.
Solution 3: Non-PoE Switch + PoE IP Camera
In this solution, a PoE injector would be needed between the non-PoE switch and PoE IP camera. The function of PoE injector is to supply power to the end IP Cameras.
Solution 4: Non-PoE Switch + Non-PoE IP Camera
In the solution, A PoE injector and a PoE splitter are both needed.
Solution 3 & 4 are suitable to the reconstruction of traditional network.
In the past two years' security exhibition, it can be seen that PoE technology is going to be more and more popular from the increasing diversity of PoE equipment displayed by large and medium sized enterprises. With the price of PoE devices falling down, PoE technology would become a mainstream security monitoring application.
