INSTALL THE HARDWARE
ADJUST THE BRACKET:
1. Place the camera on the roof of the vehicle and slightly tighten the bracket plate at the
curve slots of the plate designed for this purpose.
2. Adjust the bracket into the desired position. Beware, fingers may be trapped and an injury
may occur.
3. Tighten the screw back.
1. MOUNTING
The bracket can be mounted onto different surfaces. Use appropriate screws for installation
according to the mountable surface.
Remove protective film from the protecting plate (on the camera front) before using
the camera.
It is recommended to secure the camera by a cable (carabiner) to the roof of the vehicle
or to the vehicle roof rack.
Do not overtighten the screws.
Failures due to inappropriate installation void the warranty.

SOFTWARE REQUIREMENTS
The standalone M402 is developed to operate without any kind of special software. That means
that it does not require any special ARH software to be installed by the customer.
SOFTWARE REQUIREMENTS:
For network setup, administrator (root) privileges are necessary on the OS.
Web browser: Mozilla Firefox 47, Internet Explorer 10-11, Google Chrome 51 or later
editions. It is recommended to update your browser (Firefox or Chrome) to the newest
available version to reach highest performance.
ANPR is delivered separately. It has to be installed by the customer after purchase.
To enable all camera functions, enable JavaScript and ActiveX control in your browser.

ACCESSING THE CAMERA
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 turned 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. For more
information, see Appendix.
3. Use the ping command to test the communication with the camera:
Windows: C:\>ping -t 192.0.2.3
Linux: username@mylinux:~$ ping 192.0.2.3
4. Soon, the ping package returns: Reply from 192.0.2.3. If not:
ofirst check the Ethernet LEDs at the PC or the switch side
ocheck whether the IP address is set correctly; the own IP address of the PC can
be pinged.
oproxy is set in the browser or the browser is not set to offline.
If these obstacles are checked and there is still no reply, 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.
Make sure that the connection is capable to provide POE.

After the first start the following window will appear:
The firmware version of the camera can be seen on the right lower side of the screen.
New firmware versions are regularly released. If update is necessary, do not hesitate to contact
the support team of ARH.

RECOMMENDED CAMERA POSITION
A good ANPR engine can read the plates from images taken in various conditions. However, if
you want to achieve over 95% recognition rate with short recognition times, you have to calculate
the position of the camera accurately.
Please observe the following hints to achieve the best position:
1. Recommended to monitor the oncoming traffic
2. The camera has to be mounted on the vehicle corresponding to the direction of the
travel, panned to the left (~25° relative to the longitudinal direction of the oncoming
vehicles) and slightly tilted down (inclined ~3° down relative to horizontal):
Height of the vehicle rooftop may change the tilt angle (~2° difference).
Try to keep the license plate in a horizontal position in the live view (see above image).

3. Two lanes has to be covered on the live image and the entire vehicle has to be seen on
the image on the farther lane:
From the point of ANPR/LPR the most important is the size of the characters on the image. For
English characters it is recommended to have at least 16 pixel average character height, for
Arabic or other special characters it is recommended to have 20 pixel height (due to they are
more calligraphic than the English characters). The too large characters are also not suitable for
ANPR, therefore try to avoid settings where the character size is greater than 50 pixels in height.
A line width of a character on the image should be at least 2 pixels.
A properly set camera should provide a similar image:
A proper sample image for ANPR
Proper character sizes (in pixels) on the sample
image

MAINTENANCE / STORAGE
The cameras are designed for 24/7/365 work for every weather condition and they do not need
special maintenance. Please keep clean the camera front. During the cleaning process, avoid
scratching the front cover.
Do not use the camera without its sun-shield in hot environment, because it was specially
designed to provide proper air-cooling.
The cameras should be stored in low humidity environment in temperature range of -35 °C to
+ 55 °C. Always use the sealing caps on the connectors to keep the camera unit waterproof! If
you miss to use it, the warranty will be void!
The maintenance of the devices is recommended on a quarterly basis. In case of extreme weather
conditions more often.
During the maintenance, make sure that:
the camera operates properly,
it is facing to the previously set direction,
the fastening is not slack,
the front of the camera and the camera itself is clean (no spider webs or any other
contaminants inhibit the visibility),
there are no strange circumstances (vapor, damage).
