Phantom Ultrahigh-speed Camera Manual
The primary input is where you plug the 280W A/C power
supply provided with the camera. This is your primary
source of power for the camera. You can optionally
connect a backup source of power–often a battery–to the
backup battery power input. If the camera power switch is
set to AUTO, and if there is a loss of power on the primary
input, even momentarily, the backup power will imme-
diately take over - providing uninterrupted power to the
camera. This is important to protect any images stored in
the camera’s high-speed memory from accidental loss.
Connecting power to the battery backup port will not turn
on the camera. (See FAQ about the AUTO/ON/OFF switch.)
There is no drain from the connected battery unless a loss
of primary power causes the power input to switch to the
battery backup.
The battery backup port will not charge a connected
battery.
In case of primary power loss, the backup battery port
will not only protect images saved in memory, but can
provide sufficient power to power all camera operations
until the input voltage drops below the minimum required,
~ 18VDC.
If primary power is restored, that again becomes the
power source for the camera and the battery port reverts
to a backup mode.
The GPS port on the Phantom v2512, v2012, v1612
and v1212 can be used to provide date, time and
location information from the GPS satellite network.
Vision Research sells a compatible GPS receiver
(VRI-GPS-18X-LVC-5M). With the GPS receiver
connected to the camera, and assuming it has a valid
satellite fix, GPS timing can be used similarly to IRIG
timing. You can synchronize the camera’s internal clock to
the GPS, timestamp frames with GPS timing accuracy, and
even save the camera’s latitude and longitude with any
cine file (location error is < 3 meters after a satellite fix.)
The GPS connection supplies 5 volts at 0.2 A maximum,
and an RS-232 connection to a GPS device.
1 PPS pulse is used for timing in the camera.
I see there are two power
inputs ports. One is the Primary
DC Power and the other is
Battery Backup.
How do these work?

on the back of the camera.
