As all professional systems based on image processing and artificial intelligence, 

STA  needs  its  Technical Requirements,  to  achieve  the  maximum efficiency.

The  Technical Requirements  of  STA  can be divided into four categories:

1-  Computer  Hardware  &  Software

2-  Camera Type

3-  Camera's  angle of view  &  installation height

4-  Night Lighting

The Technical Requirements of  STA

2-  Camera Type

STA  can use all standard outdoor cameras ( including analog cameras & IP cameras )  with:

        Preferred/Optimum  Video Size:  640 x 480  Pixels  ( and at least  320 x 240  Pixels, at low bandwidth network )

        Preferred/Optimum  Frame Rate: 15 Fps  ( and at least  12 Fps, at low bandwidth network )

Note: The camera as possible should be able to provide a clear, stable and noise-free image.

Note: The camera should be fixed, but if you are using a PTZ Camera, you should keep it fixed or define a home preset (position) for it-

          to return to the intended position (maximum after 30 seconds), STA will be coordinated automatically to continue the operations.
3-  Camera's  angle of view  &  installation height

The camera should be  mounted  at  a height  that  the camera image ( purview )  covers a rectangle  with length at  least 16 meters

of  the  road surface.

The best viewing angle can be achieved at a height between 15 and 30 meters,  also you can somewhat increase the purview using -

a  wide-angle  lens.

Note: if it is not possible for you to install the camera at the proper height,  in some cases you can mount the camera at other height

and angle by applying some special software settings ( e.g. rotating the image of pedestrian bridge's camera in STA ), 

but in this case, the efficiency of operations will be reduced !

In the best view,  the camera's mast should be installed at the roadside and the angle of view should be almost perpendicular to the -

road surface, but you can also set the camera with an angle to the camera's mast ( between  0° and  45° ).

Please read:  Why these conditions are chosen as the best mode ?

The direction of vehicles should be 'Left To Right' or 'Right To Left' or 'Both' ( Horizontal ),

but  if  it is not possible for you  to  mount the  camera  in  this  position,  or if the direction of vehicles in the current camera view is :

'Up To Down'  or  'Down To Up'  or  'Both'  ( Vertical ), 

you should  rotate  the image before start the operations  using  the  'Video Rotation Tool'.  This  option  is  available  in:

Options Menu  >  Video Sources & Options  >  Video Settings  >  Video Rotation.

Note:  The camera's mast should be tightly so that the wind not able to shake it !

( also  it is  possible  to  install  the  camera  at  the proper height  on  buildings )

4-  Night Lighting 

If the road light (the light sources for the night) is not enough at night,

you may need a Floodlight ( preferably 3x3 or 2x2 ) on the road-side

to brighten up the road, and overcoming the reflection of vehicle lights

on the road surface (to avoid reducing the accuracy of the operation).

The Floodlights can be mounted at a height between 3 and 6  meters.

Note: If it is not possible for you to install a floodlight on the road-side

         you can enable and use  "Anti light-reflection filter"  in  STA.
With a 2x2  Floodlight at the roadside ( at a height of 3 meters )              Without  Floodlight ( Disorder in detecting, on a dark road )
1-  Computer  Hardware  &  Software


    For a single instance ( single run ) of application to process only  1  video stream:

        - Processor (CPU): 
          Equivalent 2.4 GHz  Dual Core  [ Intel® Core™ 2 Duo 2.4 GHz / AMD Athlon™ 64 X2 5600+ 2.8GHz ] or faster.

          Note:  The processing volume is directly related to the traffic volume.

        - Available Memory (RAM): 1 GB or more ( if x86 OS ) / 2 GB or more ( if x64 OS )

    For multiple instances ( multiple runs ) of application to process up to  10  video streams concurrently:

        - Processor (CPU): 

          [ Intel® Core™ i7 series 970/3920XM/3960X  or  equivalents in  Intel® Xeon series /

          and equivalents in AMD Processors ] or faster.

          Note:  The use of multi-core processors recommended.

        - Available Memory (RAM):  6 GB or more ( x64 OS )

    Display:  1024 x 768 minimum display resolution.

    Other: For more performance, the use of  a  Soundcard,  and  a  Speaker to listen to the sound effects,

                alerts, and spoken messages recommended.


    Operating System:  Microsoft® Windows®  [ XP,  2003,  Vista,  7,  8,  8.1,  10 ]  [ 32-bit  &  64-bit ]

    Other:  DirectX 9 or later.

A good angle of view (about 20°) 
at a proper height (about 18 meters)                   
The maximum acceptable angle of view (about 45°)
