PoE IP cameras, namely Power over Ethernet cameras, refers to the ones that get power and transmit videos through a single Ethernet cable (Cat 5, Cat 5e, Cat 6, etc) with no extra power cable needed. POE IP cameras is easy to set up and highly secured. With minimal wiring hassles, it can transmit data and power with a single Ethernet cable, eliminating tangled cords and simplifying cabling around the house.
For a POE IP camera to work, all you need to do is connecting the camera to the router with a POE cable. We often use PoE switch or injector to connect your PoE IP camera to a non-PoE router for power and network connection. The difference between a switch and a injector is that a PoE injector has only one port and therefore can only support one PoE security camera.
If you have multiple cameras, you may use a PoE switch, which usually comes with 4 or 8 ports, to reduce cabling. For example, if you want to put several PoE IP cameras outside your house which are far away from the NVR, you may use a POE switch to connect those camera and then run a single switch cable back to the NVR.
Cat 5 or Cat 6 security cameras are commonly known as PoE (power over Ethernet) IP cameras, or Ethernet security cameras. They can be directly connected to a network video recorder (NVR) with PoE ports, or plugged into a PoE switch/PoE injector before connecting to NVR, which will later be connected to a network router. Then the security camera will be up and running. But what's the difference between Cat 5 and Cat 6?
- Category 5 cable, also known as Cat 5, is a type of Ethernet network cable used to transmit video signal and supply power to network IP cameras. Cat 5, Cat 5e, and Cat 6 are Ethernet cables that supports different internet speed, bandwidth and transmitting distance. Despite the differences, all Ethernet cables can be plugged into the same network port.
- Many PoE camera users agree that the Cat 5 Ethernet cable is sufficient enough to power most IP security cameras. Of course, Cat 6 Ethernet cable is the much more future-proof and would be more advanced than Cat 5 or Cat 5e in terms of stability and speed.
