INTRODUCTION
A data collection system configured as part of the UFO Data Acquisition Project
(UFODAP) utilizes UFO Data Acquisition System (UFODAS) components. A UFODAS
consists of a number of hardware and software components including cameras, cables,
a Power over Ethernet (PoE) Injector and software. This document will guide you
through the initial physical and software selection and setup of these components.
The basic unit of a UFODAS is a Data Acquisition Unit (DAU). There are several types
of DAUs:
•Optical Tracking DAUs (OTDAU) which provides all of the functions to stream,
analyze, detect and track targets in video streams from cameras
•Multi-Sensor DAUs (MSDAUs) which collect data from non-optical sensors
including magnetic, gravitational, GPS and RF data
A complete UFODAS installation includes one or more DAUs and supporting
components. Planning your system involves the following considerations:
•Site selection –Verification of usable viewing site lines to the intended field of
view.
•If you will collect data from one or more cameras, Multi-Sensor Data Acquisition
Units (MSDAUs) or both.
•If you are using a camera(s), selection of the type of camera(s) for your situation
-- Pan-Tilt-Zoom (PTZ) or fixed, optical field width and, if PTZ, maximum zoom.
•Equipment mounting methods –Using a tripod for temporary field studies or
implementing a more permanent attachment of the equipment to a structure.
•Power source selection –Determining if AC power will be provided from a source
near the installation or if the system must be self-sustaining, using, for instance,
a solar/battery inverter power source.
•Communication infrastructure –Availability of local or remote routers and internet
connections and whether the OTDAU or MC software will be run on one or more
computers and whether those computers are local or remote.

•Communication interfaces –Cable runs, connections to routers or computers
whether by cable or WiFi and IP address setup, forwarding and additional
security measures. A camera could be hardwired to a local computer or router,
remotely connected to a computer or router via an RF range extender or
hardwired to a WiFi extender that communicates with a local router via WiFi.
•Protecting equipment from lightening-induced voltage surges.
•Software installation -- Optical Tracking Data Acquisition Unit (OTDAU) for
camera data collection and Mission Control (MC) to collect data from OTDAUs
and MSDAUs.
A minimal system could be nothing more than OTDAU software running on a local
computer and using a USB webcam on a windowsill.
The most complex installations may utilize a combination of up to six DAUs with a total
of up to 12 cameras and six MSDAUs. The six units may be widely separated with
OTDAU computers remote from their associated cameras and MC running at yet
another remote site. The internet connections that tie all these elements together may
involve local or WiFi-connected routers and possibly a dedicated server.
UFODAS cameras may be provided mounted on a weatherproof junction box with a
sealed Ethernet connector. They may be provided with a tripod mount or with mounting
hardware appropriate for permanent mounting to a building, pole or tower.
This guide shows how to implement a UFODAS system for any combination of the
above selections.

CAMERA SELECTION
OTDAU software requires one camera, and optionally two, to detect and then track
moving objects. It provides for two types of hardware and software interface to cameras:
•USB webcams which may be external to your computer or built-in
•IP cameras by Ethernet connection thru a router or directly to your computer
Two cameras may be used to track and zoom in on an object that may be first detected
in a direction that is much wider than the PTZ camera’s field of view (FOV). Making the
initial detection using a wide-angle fixed camera and handing off continuous tracking to
the PTZ camera can make best use of both their capabilities.
When the general direction of interest is known, then the selection of a single camera
may hinge on its FOV, shown as horizontal angle of view in the table below.
Another aspect of selection is the tradeoff between higher resolution and a PTZ function.
A PTZ camera can continuously track (center) a target while zooming in which
effectively increases the number of active pixels, thus compensating for its lower un-
zoomed resolution. However, a fixed camera will not experience the motion lag of a
PTZ camera and thus does a better job at tracking faster-moving objects.
Note also the difference in light sensitivity between these cameras. In color mode, this
will not be apparent during the day but may result in more granularity of the image in
very dark conditions.
Near-infrared light (700-1000 nm) is beyond what the human eye can see, but most
camera sensors can still detect and use it. When there is plenty of light, a day/night
camera uses an IR-cut filter to block the IR light so that it doesn’t distort the other colors
in the image. When the camera is in night mode, the IR-cut filter is removed, thus
boosting the camera’s light sensitivity to 0.001 lux or lower.
Each camera may be set to a “black and white” mode by accessing its Setting menus, in
Camera > Conditions > Day & Night and setting the profile to night. This removes the
IR cut filter and thus enhances the camera’s ability to image near IR wavelengths. If the
camera has an IR illuminator, it should always be disabled by setting its Mode to off in
the Illuminator menu.

SYSTEM POWER REQUIREMENTS AND SOURCES
UFODAP cameras and the Multi-Sensor Data Acquisition Unit (MSDAU) both use
Power over Ethernet (PoE) as a power source as a path for the data to a computer or
router. All six of the recommended cameras are PoE compatible meaning that a single
Ethernet cable provides the communication signals as well as power over otherwise
unused wire pairs. The single-port and 4-port power “injectors” derive approximately
56VDC from the AC line and provide it to each port. The camera then converts this
voltage to lower voltages used internally.
The hardware required for that function is known as a PoE Injector or Injector/Switch.
This is a small device that is powered from a 115/230VAC, 50/60Hz source. An
Ethernet cable connects a computer or router to the Injector’s uplink or LAN port and
another connects the Injector’s PoE port to the camera or a MSDAU.
An injector may have more than one PoE port. Each port may be used to connect a
camera or MSDAU up to the limit of the injector’s total output power capacity. UFODAP
injectors have the following capabilities:

The approximate maximum power requirements for UFODAS components are:
•50230UNI-A 30x optical zoom camera –23W max.
•42212TNI 12x optical zoom camera –12W
•NK8BR4 panoramic camera –12W
•N53AB52 bullet camera –6W
•MSDAU –4W
•PowerBeam Ethernet Bridge –8.5W
AC power for an Injector and possibly a computer may simply be from a wall-outlet in a
fixed installation or from a portable source such as a DC-to-AC inverter powered by an
automotive 12VDC source or from a solar/battery system.
Sizing a power source for a remote UFODAS installation is based on the total power
required and run time until recharged if battery storage is included.
Thus, for example, the total system power required for a field installation that includes
the panoramic camera, a 50230 camera, an MSDAU and an RF bridge to a remote
router would be 47.5W. Thus, this system could run continuously with a 100W solar
panel during the day and continue during the night using battery storage in the
GoalZero Portable Power Station, shown below. The Power Station provides a 396WH
battery and thus could sustain the 47.5W load for up to about 8 hours without
recharging. Additional 33Ah batteries could be added for longer run times.
The Power Station may be recharged by plugging it into an AC outlet or charged in the
field by means of a 100W (or larger) solar panel, as shown below.
