Browser-Based
Versatility. |
InternalWeb
is a browser-based application allowing the user to monitor
any AXT fixed-mount thermal imaging camera using any internet
or network connection (even wirelessly). All InternalWeb applications
are designed to be reliable, visually sound, and easy to use.
Currently, standard InternalWeb ships with all AXT fixed-mount
cameras.
|
|
 |
InternalWeb
resides within a broswer. |
Standard
InternalWeb allows users to access the camera from
anywhere in the world through a web browser. Controlling aspects
of the image is a snap with the browser-executed control panel.
Type in the DNS name of the camera and you're logged on. Password
protection on both the administrative level and user level
keeps InternalWeb secure.
Exploring InternalWeb's Control Panel
The Control Panel controls thermal
processing parameters as well as visual aspects of the TV
and Web video.

| Screenshot:
This opens a new window containing an instant
snapshot of the video feed. The snapshot is in
JPEG format. |
Statistics:
When enabled, a statistics bounding box appears
in the center of the image displaying the mean,
minimum and maximum temperatures. |
Time/Date
Stamp: When enabled, the camera will
synchronize with an NTP server to display the
time and date in UTC/GMT format. |
| Motion
Detection: Toggles
a frame differencing algorithm to capture time-variant
temperature changes. For example, shooting a cooling
brake reveals how much it cools frame-to-frame.
|
Emissivity:
This sets the emissivity property of the frame
with a value of 0.1 to 1.0. For example, an opaque
material that has an emissivity of 0.95 is 95%
emissive and 5% reflective. |
Downwelling
Temperature: This is the temperature
of the radiation that is reflected off the target.
If the emissivity is 0.95, then 5% of the energy
received by the camera is reflected energy of
this temperature. |
| Scaling:
Sets user-defined or automatic scaling. Automatic
linear scaling creates identical increments between
the lowest and highest value. Automatic logarithmic
scaling alters these increments. |
Atmospheric
Correction: When enabled, this corrects
for atmospheric transmission and path radiance
for a 20m path length to get more accurate temperature
measurements at long range. |
Integration
Samples: This controls the number of
subframes the camera will average before producing
a frame. A number approaching 1 produces a higher
framerate with more noise while a number approaching
128 produces a lower framerate with less noise. |
| Measurement
System: This setting switches, on the
fly, between the Celcius and Farenheit temperature
scales. |
Color
Palettes: Colorizes the image for better
qualitative analysis. There are 13 available color
maps. Download screenshots to sample each. |

Exploring InternalWeb's Settings and Preferences
The settings and preferences page allows the administrator
to configure the camera as they see fit. Administration settings,
network settings, settings for the trigger feature, and camera
settings are available. Only the administrator may access
this page.
| Administration
Settings |
|
|
| Password:
Allows for administrator password changes. The administrator
has access to the settings and preferences page as well
as the users page. The username for the administrator
is locked on 'admin.' |
Load
Defaults : This will restore factory defaults
to the camera.
System Reboot : This reboots the camera
remotely. |
|
| Network
Settings |
|
|
| Static
IP: Let
DHCP aquire network identity automatically or set static
IP, Subnet Mask, Gateway, and DNS Server addresses to
lock the camera's identity on the network. |
DDNS:
Used in conjunction with a Dynamic DNS provider. This
allows the camera to have a permanent world wide web
address even when the ISP changes the temporarily assigned
IP address. |
UPnP:
Enabling this feature causes an icon of all active cameras
to become visible in 'My Network Places' for easy network
access.
Camera Name: This gives the camera
a meaningful name, allowing it to be accessible more
easily using a browser. |

|
| Alarm
Processing: With this, the user inputs the
address of an Advantech ADAM I/O module and the camera
will control that device to output analog thermal alarm
signals. This is used in conjunction with the SIFTA
module. |
P.I.D.
Processing: This is another ADAM address input,
allowing the camera to simultaneously control an additional
device for output of recommended heating power values.
This is used in conjunction with the ThermoP.I.D
module. |
|

|
| Video
Processing : The user can opt to disable video
processing, cutting output to the television monitor.
Digital data is still available for displaying thermal
imagery on a host PC. Disabling video processing increases
performance. |
Clock
Source : The camera may free-run with its internal
clock, framing at will. However, AXT fixed-mount cameras
are also equipped with a V-Sync trigger port to synchronize
frame capture with an external event. |
Video
Format : Cameras are equipped to output an
NTSC (North American) TV signal or a variety of International
PAL formats.
S/C-Video Output: These TV ports can
be shut down. A color bar may also be displayed in its
place. |

InternalWeb,
the browser-based firmware of AXT thermal
imaging products, requires two browser
plug-ins to function correctly.
