1. Overview
P. 2
PerfectPrime provides you a way to sense the invisible, measure the
unfathomable, and analyze the improbable by providing thermal image
and temperature measurements in a new way. This Guide provides you
all the information you will need to operate the IR203.
The IR203 is powered by the host device, no charging or battery is needed

5. Getting Temperature of a Point
P. 6
The SenXorProViewer App allows
the user to get the temperature of a
particular point by touching the
location on the thermal picture. The
crosshair on the thermal picture
indicates the selected X Y
coordinates and the corresponding
temperature is shown on the screen

6. Choose Color Palette
P. 7
The SenXorProViewer App allows the
user to choose preset color palettes to
map temperature values to dierent
colors, include grayscale, colors and
combinations.
16 preset color palettes are provided
for image visualization, temperature
data is not aected. Tap the palette
list, select one of the palettes on the
drop-down list and result will be
applied to the new thermal image.

7. Enable Filters for Better
Picture Quality
P. 8
The SenXorProViewer App supports the following types
of image ltering that serve to improve the intrinsic
noise of the detector:
Temporal lters -- these work in reducing the temporal
uctuation of individual detector pixels from one
thermal frame to the next:
• Simple rolling average -- accessed via the Averaging
button, with recommended values of 2 or 4 (number
of frames over which the averaging is performed.
• Predictive temporal lter – access via the Temporal
Filter. The strength of which can be selected between
low and high, depending on the dynamics of the
scene. For static scenes, high strength is recommend-
ed, while for scenes with motion, low strength is
recommended to avoid ghosting artefacts in the
video.
Spatial lter – access via the AI Pre-trained Filter. This
lter works by reducing the noise within an individual
frame by considering the relation between the values of
individual pixels within the frame. It is enabled by
default and works best in conjunction with the temporal
lters.

8. Contour Detection
(Beta, Experimental)
P. 9
The Contour Detection feature is for DEMO
purpose only, not for medical advice or
usage.
The SenXorProViewer App supports an
indicative contour detection as an
experimental feature. The function is based
on the detection of the hottest region within
the captured image-- then display the mean
of the hottest region.
The SenXorProViewer App shows the
contour of the hottest spot that is
automatically detected. Since the model
involves some parameters, the user has
control over them to ne tune the threshold
and obtain a more stable readout.
The model is intended for distance between
the camera and the subject in the range of
0.7 to 2 m.

9. Menu Settings
P.10
The setting of Filters, Contour Detection, Temperature Unit and Emissivity
and Language Selection can be found in the menu. Each setting is saved after
change and will be kept even the SenXorProViewer App is restarted.
Emissivity is a property of the material of each individual object in the eld of
view. It quanties the ability of an objects surface to emit long-wave infrared
radiation and strongly aects the temperature readout from the IR203. By
default, the emissivity is set to 0.95 which is a representative value for many
common objects with matt surface, as well as the human skin (in the range of
0.95 - 0.97). Note that metals tend to have a dramatically lower emissivity as
low as 0.1, and it trongly depends on their surface processing. The user can
adjust the emissivity according to the exact object of observation.

10. Recording Functions
P.11
Thermal video can be stored to the camera roll
by pressing the save button on the video
streaming screen.
To capture thermal photos, switch to photo
mode
and press the camera button. The photos
captured are stored in the camera roll.
Note: The SenXorProViewer App does not
collect or save any thermal image or video
unless the user selects to save a picture or
video to the device.
