**Additional devices include HDMI over Cat-5 transmitters can be powered with this system as well. Allowing installations to run two Cat-5 cables for power, video and control.
Note: PTZOptics HD-SDI Camera models now include built-in PoE Support.
This device provides a low cost solution for delivering power to a 12 volt camera or routers over 328ft of network cable for a non-PoE PTZOptics camera such as a Huddlecam. This device allows power to be carried on 10/100/1000 networks with either 802.3af or passive injectors and switches with a CAT5e, CAT6 or CAT7 Ethernet network cable. Intended for use with Cisco or similar PoE switches – this active PoE solution negotiates with the switch to activate power and provide it to the client device. It is a compact and cost effective power solution. The switch supplies 48 or 56 volts DC at the source location. The higher DC voltage means the current is reduced by a factor of 4, and then carried with less loss over the 10BASE-T or 100BASE-T network cable. The splitter extracts the DC voltage from the network cable and reduces the voltage to 12v, and increases the available current by the same factor to power the camera on the EIAJ-04 splitter DC plug. Unlike simple injector / splitter sets, this combination of a 48v source and 12v converter allows you to extend the distance with this product for this application up to 328ft or 100 meters. We also offer kits with up to 16 injectors and splitters – so one power supply can feed 4, 8, 12 or 16 cameras. These kits include the Multi Port Passive POE injector and a power supply of either 30 watts, 60 watts or 120 watts.
Step a) connect EIAJ-04 DC cord to your camera,
Step b) connect RJ45 male to your camera
Step c) use a factory Ethernet cable to connect the RJ45 female to your PoE switch up to 100 meter distance
In this video series, we will be reviewing how to set up multiple PTZ cameras powered over ethernet. We will be using a PoE switch (Air Link ASW408POE) provided by Texas Wifi and a few Power Over Ethernet 12V break out cables (WT-AF-PTZOptics). These breakout cables provide ethernet and 12V power (for the cameras) coming from a single PoE switch.

This particular PoE (power over ethernet) switch is ideal for PTZ camera projects including up to 4 cameras, because the switch include for PoE enabled ports. For projects with more than 4 PTZ cameras you will need a network switch with more ports that are PoE enabled. The breakout cables used provide Power and Ethernet to for the camera which is ideal because it can be used with any PoE enabled switch. This also allows for camera control, IP video streaming and of course powering the camera.
Texas Wifi is a great company to call with questions about Power Over Ethernet. As promised a link is provided below to their website. Keep in mind that you do need a barrel adapter for the 12V power provided at the end of this PoE injection cable.
A question we recently received was “How many cameras can we put on a single Gigabit Switch?” Look for the answer on Tech Chat w/ Matt this Wednesday!
