How to detect in an easy and convenient way if the camera suffers from a failing shutter mechanism (FFC > Flat Field Correction) which can result in white or ghost images?

Below instruction helps you to:

• Identify if the camera possibly suffers from a random failing shutter (FFCwhich uses the FFC (Flat Field Correction)
  
  • instead of waiting for the FFC taking place approx every ~10min, you can now fire it on command.
    
    
• And As well instructs you what to collect for the Technical support department in order to allow a RMA

In order to Execute To Control the shutter and execute the FFC-command on demand in a convenient and controlled way, you can use for example one of the below 3 2 methods:

1. MIC IP fusion 9000i : Sent AUXON-467 to Execute a Flat-field correction
2. Sent CGI command via the web browser:
   MIC IP fusion 9000i : http://ipaddress/rcp.xml?command=0x09A5&type=P_OCTET&direction=WRITE&num=1&payload=0x800004050C030127020003
   Or Copy/Paste below script in the "Alarm Task Editor"
   this way you can execute the FFC by calling pre-set 62
   // this script shall fire the FFC command when preset 62 is reached, so create this preset upfront
   // when Preposition 62 is called it shall check every 500 mS if the preset was reached
   // ones a positive position reached is received the FFC command is fired
   // Payload("0x000601307000xx0002") where xx is the Preposition # in Hex. preset62 in this case
   MessageCheck position_reached:={Message("rcp.xml?message=0x09a5") Payload("0x0006013070003e0002") IP("127.0.0.1")};

   //Define a Timer for 500 mS
   OperationMode triggerhalfasec:={Low(1)High(5)};
   TempState(1):=triggerhalfasec;

   //The MessageCheck will occur every 500 mS
   if(TempState(1)) then position_reached;

   // RCP FFC command
   RcpCommand ffc:={Command("DINION IP thermal 8000 : http://ipaddress/rcp.xml?command=0x09A5&type=P_OCTET&direction=WRITE&num=1&payload=0x0004050580

1. Activate before reproduction:
   1. Date and Time stamp + Milliseconds
   2. On Screen Display > AUX-ON 60
   3. Coordinates > AUX-ON 95
   4. Create a new preset and set the Optical view to the same zoom factor as the thermal view, so both images showing the same FoV (Field Of View)
      below command can help you to quick align the optical with the thermal view
      

      1. Match HFoV-zoom of MIC9k visible to thermal 320 (QVGA)

      3. Match VFoV-zoom of MIC9k visible to thermal 320 (QVGA)
         http://ipaddress/rcp.xml?command=0x09A5&type=P_OCTET&direction=WRITE&num=1&payload=

   // if it reaches the preposition, then fire ffc command
   if(IsActivated(position_reached)) then ffc;

   Create preset 62 and name it FFC
   note: for this script it MUST be 62, if you want to use another preset you need to modify the script

3. How to reproduce
   
   

   • Record the fault reproduction:
     
     Preferred recording method to use screen-recording and set optical and thermal image side-by-side
     this way support can see the exact steps that are taken for the reproduction,  as-well judge the thermal deviation in contrast to the optical view.

     note: In case the scene is sensitive due to security policy you can also zoom-in (optical only) and point camera elsewhere like sky or ground

   but

   • , preferable the scene should contain thermal contrast

   preferred method to use screen recording and set optical and thermal image side by side

     1. Alternative footage options are:
        
        1. When ActiveX is installed the Internet Explorer live page also has a record button
        2. When using BVC the live page also has

   • 1. 1. .
        2. Any other type of footage is also good

                   Make short video clips of ~1min of each failing camera containing approx 4 x FFC (move the Camera and wait 15seconds between each FFC)
                   a successful FFC can be recognized by the blue square that short appears in the corner

1. • Reproduction steps:
     
     1. Call the new created preset
     2. Use one of the

2. • 1. 2 methods to fire FFC > briefly a blue square is displayed in the corner indicating the FFC takes place
        
     2. Move camera a bit
     3. Fire FFC again

   • Provide to Technical support from each failing camera
     
     1. 1min of video with 4x FFC (fire every 15sec)
     2. Camera maintenance log
     3. Type of power used for the camera
     4. screenshot of the camera Overview page
     5. Used firmware, preferable the test took place with latest camera firmware
     6. How many Thermal cameras does the customer has, provide overview of installed base incl serial numbers
     7. How many are failing, provide serial numbers
        
        
   • When after following above troubleshooting steps, and their is a strong indication a RMA is required But
     the unit is installed in locations that are difficult or expensive to swap, Examples would be:
     1. traffic areas that require lane closures,
     2. remote locations that require many days or weeks to arrange required access (getting lifts on site),
     3. or if the downtime is causing operational costs (requiring a guard on site until system is repaired).
