Power Connections Overview
The XT Camera System is designed to provide a number of flexible powering
solutions by either Power over Ethernet, devices supplying power over USB-C
cable or by using the XF Power Supply accessory.
Power over Ethernet (PoE)
The IQ4 supports the Power over Ethernet (PoE) which can deliver sucient
electric power to keep the XT Camera System running smoothly during normal
usage without having to recharge the battery. The attached router/switch
obviously needs to support Power over Ethernet (PoE) for the power delivery
to work.
Note that if you have Live View running (or are using Live View over HDMI) for
a prolong period, the IQ4 might use more power that can be delivered via PoE
and the batteries will thus not be charged.
If your router/switch or computer doesn’t support Power over Ethernet, you
can add a Power over Ethernet injector device to the network. The PoE-
injector plugs into an electric outlet and adds the power to the Ethernet cable
loop. Make sure that the injector point is added between the IQ4 and the
router/switch or computer to work.
The PoE standard supports up to 15.4 watts of output power, but in practice a
POE Router or Injector and the cable connection will provide around 13 watts
of power. As already mentioned, this will be enough to keep the XT Camera
System running during normal usage without the need to recharge the
batteries. However, if you are using Live View constantly, the XF Power Supply
and the USB-C power delivery options can provide more power to the IQ4 so
consider using one of those for this specific usage case.
Power over USB-C
XT Camera System will intelligently draw as much power as possible over the
USB-C connection, which can be plenty to keep the system running without
having to recharge the battery. This is done on the IQ4 by using the USB
Power Delivery (PD) standard to negotiate with the power supply on the
attached USB-C device (it can in theory draw up to 16V and 3A).
The IQ4 is thus capable of drawing plenty power over USB-C to keep the XT
Camera System running under heavy usage with Live View while also being
able to charge the battery. This means that USB-C connection can provide
notable more power than Power over Ethernet, but please be aware that few
computer USB-C ports are actually able to deliver this level of power. As an
example, the USB-C port on a newer MacBook Pro will provide 5V with a
maximum current of 1.5A, which translate into a maximum power of 7.5 Watt.
Even if the USB-C port on your computer only provides 7.5 W, it will obviously
prolong the use of the XT Camera System before having to recharge the
battery. The IQ4 might not use more than 5-6 watts when idle, so a bit of
