Accessing the Camera
In order to access the camera, it has to be connected appropriately. For more information see ParkIT Install Guide.
For communication with the camera, camera commands have to be used. The easiest way of handling these
commands is through the web interface of the camera. For more information on other communication methods
see ParkIT Programmer’s Manual.
Access from Browsers
Steps of accessing the web interface of the camera from a browser:
1. Connect the camera to a computer or network switch then power on the camera.
After it is powered on, both status LEDs (red and green on the camera front) are turned
on while the camera is booting. After finished, the green status LED flashes two times
while the red one turns off signaling that the camera is ready for operation.
2. Enter an alternate IP address (or set your computer’s IP)
in the 192.0.2.x subnet – where x is an integer number
between 1 and 254 except 3 – with the subnet mask of
255.255.255.0.
3. Use the ping command to test the communication with the camera
Windows: Linux:
C:\>ping -t 192.0.2.3 username@mylinux:~$ ping 192.0.2.3
4. Soon, the ping package returns: Reply from 192.0.2.3 If not, power off then on and enter the
previous ping command again.
5. Start a browser then enter the default IP address of the camera into the address bar
(http://192.0.2.3). After this, the camera starts with administrator privileges, ready to be set up and
configured.

Configuration Wizard
The ParkIT camera must be configured before using. Use the Configuration Wizard for setting up camera features
(e.g. zoom, focus etc.) quickly and easily. The wizard guides users through the main calibration steps configuring
various properties of the camera including the Event Manager. Of course, the use of the wizard is optional –
camera properties can be set manually as well.
Steps of the Configuration Wizard:
Step 1: Set network settings to communicate with the camera. See Network Setup for more information.
Step 2: Time and date settings. For more information see Date and time.
Step 3: The Wizard can optimize the camera for ANPR (Automatic Number Plate Recognition) or Overview
purposes. Select the one that is appropriate for your purposes.
Step 4: With the help of the Automatic Zoom (ZFG - Zoom From Geometry) feature, optimal character size on the
camera image for ANPR can be reached quickly and easily. To use autozoom, enter the required data (e.g.
distance of the number plate) into the textboxes then click next. Click ‘Skip’ to set zoom manually.
Step 5: Based on the values provided in the previous step, the camera creates a red rectangle that should include
the license plate completely. If not, then adjust the position of the camera in order to do so.
Step 6: Use the Autofocus feature to achieve sharp camera image. The focusing process can operate on the entire
camera image or on a specified section of it. Use the rectangle to select the area for the Autofocus.
Step 7: Configure the basic camera parameters. For more information see Easy Setup description.
Step 8: Configure triggering and trigger events. For more information see Event Manager description.
Step 9: Set or create camera profile. For more information see Profiles.

Profiles
Under the profile menu, the list of profiles can be viewed. Camera profiles are pre-set camera configurations
containing a complete set of settings that are loaded at startup and cannot be changed at runtime. One of the
profiles has to be always active and the active profile cannot be deleted.
The camera has a pre-defined default profile that cannot be erased but altered only or Set as current by users.
NOTE: To activate new profiles the camera must be restarted.
Creating new profiles
New profiles can be created according to the followings:
1. Click Create new on the ‘Profiles’ page.
2. Customize the new profile by setting the parameters of the ‘HTTP server’, ‘Hardware layer’ and ‘Live view
setup’ menus.
3. Enter a name for the new profile and click Save.
NOTE: Maximum 32 different profiles can be created.
Export profiles
Settings of camera profiles can be saved into a .tar.gz file, ready to be uploaded to other ParkIT cameras. The name
of the file will contain the exact date and time of exporting as follows: yyyymmdd_hhmmss.tar.gz
E.g. 20120620_101422.tar.gz
The saved settings can be uploaded to other ParkIT cameras by browsing the .tar.gz file in the Setup/Update page.
Export profiles, users and groups
Besides saving all profile settings into a .tar.gz file –just as in case of ‘Export all profiles’–, this option also saves
user and group configurations. The result will be a compressed .tar.gz archive as detailed in the previous option
and can be uploaded to other ParkIT cameras in the same way.

Hardware Layer Setup
Capturing
Image capturing frequency of the sensor:
The image capturing frequency of the sensor
determines the number of frames the sensor
captures in one second. Note that the actual
number of frames processed by the camera
can be further reduced with the help of the
Skipping frames and Number of skipped
frames (see next chapter) options.
This option can be used for reducing mains
flickering –caused by artificial light sources–
on the camera image. By this value, the
camera can be synchronized to the mains
frequency of its environment (230V@50Hz or
110V@60Hz).
Skipping frames: Frames captured by the
sensor can be skipped and omitted from
processing.
0 = no skipping, the system processes all
images
1 = every second frame is processed
7 = every eighth frame is processed (it
drops 7 frames than keeps one)
Number of frames per second: This option calculates the actual FPS value from the Image capturing
frequency of the sensor and the Skipping frames values.
Flashing
Number of flashes on the built-in illuminator in one second: Flashing frequency of the illuminator.
Image rotating, mirroring
The system is capable of rotating and mirroring images.
Rotate in degrees (0 or 180). Camera image rotation in degrees.
Horizontal mirroring: If ticked then horizontal mirroring is enabled.
Vertical mirroring: If ticked then vertical mirroring is enabled.
Image buffering
NOTE: Image buffering parameters are read only.
Reserved memory size for the GXD system (Mbytes): Maximal size of memory for the system. The rest of the
memory is used as image buffer. This memory is dynamic, if the system needs more memory it allocates for
itself automatically.
Maximal size of an image: Max. size of images in the camera memory.

Easy Setup
Image
Focus - Manual focus adjustment. Set focus to make the camera image sharp.
Start Autofocus - By autofocus, the camera adjusts focus automatically until it detects that the camera image is
sharp. Autofocusing may also include automatic brightness adjustment if the brightness of the camera image is
not satisfactory for the autofocusing process.
Zoom - Manual zoom adjustment. Set zoom to reach the intended camera view.
BrightNow! - The BrightNow! function automatically adjusts gain, shutter and iris to achieve the selected target
value (Brightness target). With the help of BrightNow!, the optimal brightness of the camera image can be reached
quickly but less accurately. When the target level is reached, the camera switches back to the previously set
autobrightness mode.
Brightness target - The following automatic brightness strategies set and maintain the value set here.
Brightness Control Mode - Strategy of the brightness controller
Manual -In manual mode, the values of gain, shutter and iris can be adjusted manually.
ANPR - Strategy appropriate for ANPR camera purposes The ANPR strategy does not let any pixels to burn
out.
Overview -Strategy appropriate for overview camera purposes. This mode allows some pixels to burn out.
Quick -The Quick controller method adapts to the brightness changes of the camera environment quickly.
This strategy is suitable for special overview purposes.
NOTE: Flash intensity cannot be adjusted in case of 1.3MP camera models.
Flash Intensity: - The light intensity of the camera’s built-in infrared illuminator can be set by this option. Note
that prolonged direct exposure to infrared light can cause permanent damage to the eye!

Image Setup
Gamma - Gamma correction used on the camera image.
Brightness - Brightness of the camera image can be adjusted manually.
Contrast - Adjust this control to change the contrast of the camera image.
Whitelevel - Defines the highest pixel value that will be mapped to white. This will be the ending point of the
gamma curve. Values between 0 and 1.0 are valid.
Black level -Defines the lowest pixel value that will be mapped to black. This will be the starting point of the
gamma curve. Values between 0 and 1.0 are valid.
NOTE: Incorrect whitelevel and blacklevel values may cause entirely black or entirely white camera image. In such
cases, reset the whitelevel and blacklevel values to default (whitelevel=1 and blacklevel=0) to restore the camera’s
live view. See Appendices to inspect the effect of adjusting the main image properties.
Compress Rate - The quality of the captured images can be set. The lower this value is, the better the quality of
the images will be. Note, that images of better quality are greater in size therefore, they increase network load.
Parameters for Color Cameras Only
Wb. Red, Wb. Green, Wb. Blue - Red, green and blue channel gains.
Saturation - The intensity of colors can be adjusted by saturation. See appendices to inspect the changes of
saturation value.
Color compensation - Color correction can be used to achieve the best color fidelity in captured images by
compensating the color of the dominant light source illuminating the scene. The following options can be set for
different light sources:
Incandescent tungsten, (CCT=2865 K) Average Summer Sunlight, (CCT=6500)
Cool White Fluorescent, (CCT=4300 K) North daylight, (CCT=7500 K)
Mid-morning Daylight, (CCT=5500 K) Auto - Auto compensation

Quick -The Quick controller method adapts to the brightness changes of the camera environment quickly.
This strategy is suitable for special overview purposes.
Auto Brightness Mode - The current strategy is displayed and can be selected here.
Light condition - Brightness settings can be set for day and night light conditions respectively. The light condition
returns the value day or night based on the camera light sensor.
Gain - Gain is the extent to which the strength of a video signal is boosted. Note that high gain values result in
noisy images.
Iris - Iris is a mechanical device that controls the amount of light reaching the sensor. If 0 then no light can pass
through to the camera sensor.
Shutter - Controls the length of exposure time. Too high shutter values may result in blurred images.
Page 15/34
ParkIT User’s Manual

Histogram - Enable it to draw image histogram on the camera view.
BrightNow! Target - The BrightNow! function automatically adjusts gain, shutter and iris to achieve the selected
target value. With the help of BrightNow!, the optimal brightness of the camera image can be reached quickly but
less accurately. When the target level is reached, the camera switches to the previously set mode.
NOTE: Flash Intensity cannot be adjusted in case of 1.3MP camera models.
Flash Intensity - The light intensity of the camera’s built-in infrared illuminator can be set by this option. Note that
infrared light can severely damage the human eye. Do not look into the light source directly.
Set - Click Set to assign different Flash Intensity values for each Auto brightness mode respectively, according to
the followings:
1. Select the Auto brightness mode and Light condition to which you want to assign a Flash intensity value (at
Mode and at Light condition).
2. Set the desired Flash Intensity value (at Flash Intensity).
3. Click Save.
As a result of this procedure, the set Flash Intensity values will be applied for the assigned Mode and Light
condition automatically when changing Auto brightness mode.

ParkIT User’s Manual

Optics Control
Focus - Manual focus adjustment. Set focus to make the camera image sharp.
Autofocus - By autofocus, the camera adjust focus automatically until it detects that the camera image is sharp.
Auto-focusing may also include automatic brightness adjustment if the brightness of the camera image is not
satisfactory for the auto-focusing process.
NOTE: The camera is capable of focusing to a specified area within its view (e.g. on a license plate). Move and
resize the red rectangle on the camera image to set this area for the autofocus.
Zoom - Manual zoom adjustment. Set zoom to reach the intended camera view.
Iris - Iris is a mechanical device that controls the amount of light reaching the sensor. If 0 then no light can pass
through to the camera sensor.
Calibrate All - Use this button for focus, zoom and iris calibrations. The motorized optics can be operated in finite
many steps. Calibration means rescanning the entire range of the optics to measure the exact position and length
of control to compensate deviations (if there are any).
Filter -This parameter is available only for cameras equipped with filter switchers. The state of a filter switcher can
be of two types:
All pass - The filter passes both visible and infrared light, use this setting when infrared illumination is
present and necessary (typically at nighttime capturing).
IR cut - The filter cuts out infrared light to maintain color fidelity on color images.
Page 17/34
ParkIT User’s Manual

Flash Control
In the Flash Control section, various parameters of the camera illumination can be set.
If one of the automatic brightness control modes is active, its flashing parameters can be adjusted and saved here.
Flash Intensity: By this parameter, the light output of the camera illuminator can be adjusted.
NOTE: In case of 1.3MP camera models, adjusting Flash Intensity and Frame Parity Flashing are not supported –
they can only be turned on/off.
If ‘Enable/Disable’ is not selected, this value stands for the illuminating light output for all frames. Otherwise, this
value is valid on even frames only.
Frame Parity Flashing
NOTE: The use of this function is required only under such special circumstances when the recognition of both
reflective and non-reflective number plates is necessary.
This option can be used to setup the camera for reading both reflective and non-reflective license plates. This task
is realized by switching to lower and higher light output between odd and even frames. With this illuminating
technique, the camera captures images with more and less intensive illumination. The former images will be
suitable for the recognition of non-reflective license plates, while the latter ones are for reflective plates.
If ‘Enable/Disable’ is selected, this value stands for the illuminating light output for odd frames and is represented
as a percentage of the Flash Intensity value.
E.g. if Flash Intensity is set to 50 and Frame Parity Flashing is set to 20 then the camera will flash with 50% power
on even frames and 10% (20% of the 50%) on odd frames.
NOTE: To assign Flash Intensity and Frame Parity Flashing values for brightness modes/light conditions, check
‘Enable Auto Brightness’ on the Brightness Control Tab.
Flash Intensity / FPF of the Current Configuration: This option represents the saved Flash Intensity and Frame
Parity Flashing values saved for brightness mode and light condition set at Mode and Light condition.
By clicking on Save, the set Flash Intensity and Frame Parity Flashing values are saved to the set Mode and Light
condition.

ParkIT User’s Manual

Motion Detection
With the help of the hardware motion detector, the camera is capable of detecting motions in image streams
based on the pixel differences between consequent frames. This motion detector can be customized for different
purposes through its settings detailed below and can be used to launch trigger events on motions.
Actual View - In Motion detection view, the live camera image can be seen to help to setup motion detection.
Note that this view is intended to help the setup process, the quality of the image stream is not appropriate for
other purposes.
When clicking Set to mask view, the mask toolbar (detailed below) appears.
Speed - By setting the speed of the motion detector, it can be specified that how fast pixel changes should be
considered as motions. If this value is set too low then slow ambient brightness changes (e.g. cloudy/sunny
weather) may be considered as motion. If set too high, even a lightning can trigger signaling motion.
Sensitivity - By sensitivity, it can be set that what extent of pixel changes of the camera image should be
considered as motion. If low, then minimal pixel changes are sufficient to cause motion, if high, only great pixel
changes initiate motion.
Frame sensitivity - Sensitivity of the motion detection frame.
Reslevel - Motion limit. The extent of pixel changes below which the detected motion is ignored (the ‘motion’ text
does not appear).
Sequence - Images containing motion are arranged into sequences. These sequences have unique IDs.
Sequence frames - The index of frames within the sequences.
Difference from background - This value represents the extent of difference between the previous and the
current image. The higher this value is the more motion has occurred.
Motion value - This value shows the extent of motion on the current image. This value is based on the sensitivity,
speed and difference from background.
Motion rectangle - The area in which motion has occurred is framed by a motion rectangle defining the place of
motion in the image. This option returns the coordinates of the motion rectangle.
Masking - With the help of image masking, certain parts of the camera view can be ignored by the motion
detector. This feature is designed for situations when not the entire camera image is interesting for triggering (e.g.
if the camera covers two lanes but only one of them is observed by the user).
