•ChapterConformity on page 13 gives you information about conformity of
AVT cameras (CE, FCC, RoHS).
•ChapterSpecifications on page 14 lists camera details and measured spec-
tral transmission diagrams for each camera type.
•ChapterCamera dimensions on page 20 provides CAD drawings of stan-
dard housing models (2D drawings), tripod adapter and cross sections of
the mounts.
•ChapterStart up on page 22 describes the first steps to get the camera
into operation: camera control signals and camera controls as well as
adjusting the image process.
•ChapterCamera interfaces on page 25 describes the control junction (I/O
pin assignment), inputs / outputs and trigger features.
•ChapterImage processing on page 35 describes the function of the
Pearleye P-007 LWIR / Pearleye P-030 LWIR firmware. It is related to the
individual modules of image processing and shows in what way the user
can control these modules via the serial interface.
•ChapterBasic parameters and commands on page 40 describes the basic
configuration options and general commands available for the user, being
important for the operation of an ex factory preconfigured camera. Most
probably the information stated here will be sufficient for most of the
users.
•ChapterAdvanced parameters and commands on page 47 describes the
advanced configuration of the Pearleye P-007 LWIR / Pearleye P-030
LWIR models. For the control of an ex-factory set up camera the
intervention within the parameters stated here or rather the use of the
mentioned commands is only necessary in exceptional cases.
• The appendix: Chapter Command reference on page 66 describes the
general command reference of the Pearleye P-007 LWIR /
Pearleye P-030 LWIR firmware.

Before operation
We place the highest demands for quality on our cameras.
Target group This Technical Manual is the guide to detailed technical information of the
camera and is written for experts.
Getting started For a quick guide how to get started read: How to install a GigE camera
(Bigeye/Pearleye/Goldeye).
Safety warnings
Note

Please read through this manual carefully before operating
the camera.
Caution

Before operating any AVT camera read safety instructions and
ESD warnings.
Caution

Electrostatic discharge
The camera contains sensitive electronic components which
can be destroyed by electrostatic discharge.
Use sufficient grounding to minimize the risk of damage.

Introduction
Pearleye Technical Manual V2.2.0
12
Caution

Environmental conditions
Operate the camera in dry and dust free environment. The
working temperature range (temperature of the camera
housing) depends on the camera model:
• Pearleye P-007 LWIR: 25°C ... 45°C
• Pearleye P-030 LWIR: 15 °C ... 35 °C
Only in this temperature range, the camera reaches optimal
image quality. Outside the optimum temperature range, the
image may look oversaturated..
Regarding the signal quality of the camera it is an advantage to
operate the camera under constant ambient air temperature.
This can e.g. be facilitated by assembling the camera on a
bigger metal corpus or by an additional active temperature
regulation.
The red LED at the backside of the camera (L3) or the value of
the register T serves for examination. If L3 permanently
lights up or rather the lowest bit of T is set, the camera
housing has a temperature which is outside of the optimum. In
this case provide an additional heating or cooling.
Note

Warm-up period
The warm-up of the camera takes 20 to 30 minutes.
To achive best performance and accurate temperature
measurements, wait until the warm-up is completed.

Conformity
