PoE Injectors 802.3af

Smart doorbells are low power consumption devices which their maximum power rate is below 10watt, because of this reason, users can take advantage of PoE technology to have a cost-effective and maintenance-free video doorbell system. PoE stands for Power over Ethernet, as the prevalent technology in IT field (PoE for access points, IP telephone, network switches), 802.3af standard has been universally accepted and adopted by different manufacturers.

Smart doorbell has an Ethernet port and complies PoE

Users can choose any PoE injector that complies 802.3af standard. The PoE injectors support 48V, 500mA specification. The PoE injector has two Ethernet port; one LAN port to connect with your router/switch, another PoE port connects to your smart doorbell.

Smart doorbell has an Ethernet doesn’t support PoE

As long as your smart doorbell has an RJ45 port, you can take advantage of PoE by using a PoE injector and PoE splitter. The PoE splitter can split the power and data from Ethernet cable, it should be connected by the end of your smart doorbell.

If you have bought SD-M5 and SD-M3, please choose a standard PoE injector works on mode A (1,2,3,6). PoE injector works on mode A (End-span) utilizing data pairs 1-2 and 3-6 to deliver power. Both SD-M5 and SD-M3 cannot work with none-standard PoE injector (Mid-span) that utilizes 4,5,7,8 pairs.

PoE stands for power over Ethernet. With PoE cameras both the power and data are supplied by the Ethernet cable. There are several different setup methods you can use when setting up a PoE camera. Below is a representation of each method we will discuss in this article:

Using a PoE Swtich

This is the most common and direct method of setting up a PoE camera. To start, run an Ethernet cable from a PoE network switch port to the PoE camera. The PoE network port will provide power and data to the camera.

Using a PoE Injector

A PoE injector will be needed only if the switch is a Non-PoE unit. An active PoE injector will supply remote power to the PoE camera via the injector. Most Amcrest PoE injectors provide up to 15.4W of power and are IEEE 802.3af compliant. To start, run an Ethernet cable from the non-PoE network switch to the input port of the injector. This will supply data from the network switch into the injector. Apply the power cable for the injector into the power port and plug the power cable into a power source (wall outlet, surge protector, etc.). Next, run another Ethernet cable from the output Ethernet port of the injector to the PoE camera. This cable will supply data and power to the PoE camera.

Using a PoE Splitter

A PoE splitter is used to power non-PoE cameras from a PoE switch. Keep in mind this can only be used if the switch is a PoE unit. A PoE splitter splits the PoE signal into a separate power and Ethernet data source. This allows you to run Ethernet cables from a POE Switch over long distances, and then split the PoE signal into a separate data and power sources to run non-PoE devices.

To start, run an Ethernet cable from the PoE switch to the input port on the splitter. This will supply data and power from the PoE switch to the splitter. Next, plug an Ethernet cable into the input Ethernet port of the non-PoE camera and plug the cable into the output port of the splitter. Lastly, use the connection adapters provided with the splitter to power the non-PoE camera. Most Amcrest PoE splitters can output voltages of 5V, 9V, or 12V.

Using a PoE Injector and Splitter

If the network switch and camera are both non-PoE but you would like to have them run as PoE devices you can utilize both a PoE injector and splitter in your setup. To start, run an Ethernet cable from the non-PoE network switch to the input port of the injector. This will supply data from the network switch into the injector. Apply the power cable for the injector into the power port and plug the power cable into a power source (wall outlet, surge protector, etc.). Next, run another Ethernet cable from the output Ethernet port of the injector into the input Ethernet port of the PoE splitter. This will supply data and power to the splitter.

Next, plug an Ethernet cable into the input Ethernet port of the non-PoE device and plug the cable into the output port of the splitter. Lastly, use the connection adapters provided with the splitter to power the non-PoE camera.
