Foscam IP Camera using POE

During Amazon Prime day; I decided to enhance the security of my driveway and Garage by adding a Foscam Outdoor PTZ (FI9928P) HD 1080p IP Camera. While I had WIFI in the garage; I wanted to wire this camera in with the other camera watching the front door but I wanted to position this camera on the Left side of the driveway so it could watch the garage door as well as keep an eye on the driveway. To do this meant I was going to need to run a very long power cable along with a 16-20foot CAT5E cable but I decided I’d rather run a Power-Over-Ethernet (PoE) connection to eliminate the long power cable run and run a single CAT5 POE configuration. The Foscam FI9928P does not natively support POE; so I’d have an injector and a splitter to enable POE for this camera.

This Blog entry is a expansion of my Amazon Review of the WT-GPOE-1-AB by PoE Texas. This device is a passive splitter / Injector which can be used on both ends of a PoE connection to inject and breakout the DC connections. I wanted to add a little detail here incase someone needs to replicate my work on their personal installation. This should be applicable to anyone trying to use PoE for any network device which has a power brick.

Installation is pretty simple. All you are going to need is two of the WT-GPOE-1-AB which thankfully comes with some DC splitter cables to connect them up to a DC power brick, some Cat5E cables, and maybe a few screws to mount the WT-GPOE-1-ABs to the wall. Total cost would probably be under $20 if you have the cat5 cables on hand. The Author picked the WT-GPOE-1-AB for several reasons:

  • Support Gigabit Ethernet speeds
  • Allows for use any voltage on PoE up-to-56V for a total of 60watts. In our case the Foscam Power adapter is capable of delivering 12VDC at 2amps for a total of 24watts.
  • Can be used on both ends of the PoE link.
  • Carries DC across all 4 pairs of the Ethernet link maximizing current carrying capabilities of the CAT6 Cable.

Let’s start with the Network side of the PoE connection. To do this you are going to want to connect the WT-GPOE-1-AB to the network switch as pictured:

Network Side of POE

The LAN side of the WT-GPOE-1-AB connect to the network switch or to anything on “lan” side of your device which you’d normally plug the IP camera into. The PoE connection would become the side which carries both LAN data and the DC power from the power supply. Finally; you’d connect the camera’s power supply directly to 45+78- DC jack of the WT-GPOE-1-AB.

Camera Side of POE

On the Camera side of the POE cable; you need to split the Power from the Ethernet (data) using another WT-GPOE-1-AB… although the configuration isn’t quite as obvious for some reason. The PoE cable from above; plugs into the “LAN” connector and the Camera plugs into the DC jack at 12-34+. The Camera’s data port then connects to the remaining “POE” RJ45 jack. The Camera power is connected with a DC to DC barrel connector also available on Amazaon.

Using two WT-GPOE-1-AB‘s I was able to transmit the DC power for the camera approximately 20ft along with the gigabit data for the camera. The small physical form factor of the WT-GPOE-1-AB allows it to fit easily on top of my garage door ledge and not interfere with the opening or closing of the garage door.
