No Picture after providing power 

      May be the power supply voltage abnormity, please check 
       he power supply voltage and pole

 

whether exactitude

       Please check all the connecting cable and monitors whether  
       be connected correctly or not

 

  

The picture level direction have flowing interference  

       ripples 

       May be caused by the power supply AC ripples, it need filter  
       the wave of the power supply

       Check the monitor and peripheral equipments used.

 

 

 

  

The picture background Colour changes continuously

 

 

       The fluorescent lamp’s electromagnetic field cause Colour 
roll.      
       This is proper phenomenon of the cameras. 
        Reduce the fluorescent lamp numbers or increase the  
        distance between the camera and the fluorescent lamps can 

improve it. 

        Use power supply external sync. camera can solve it. 
 

  

The picture smear too mass 

       The power supply’s voltage unstable

       Connecting cables not connect correctly or have high  
        impedance. 

 

                  Note

                

  

• Please note the camera’s operating temperature and  its   

    using environment

 

requirement. Avoid using the camera   

    at too high or too low temperatures. The operating tem 

    perature is 

-30

~

+

60℃

. (Recommendatory operating tem 

    perature is 

-10

~

+50℃.) 

 

  • Do not mount the camera near by the radiator

 

or heater.

 

Common Problems and Troubleshooting 

 

 Note

 

• Power supply must pass safety certification ,Its output 

voltage, current, voltage polarity and operating temper- 
ature must match requirement of this equipment. 

•  Please install lightning protection devices or cut off the 

power in thunder and lightning

 

conditions. 

• To capture high-quality video and pictures, please make  
sure the network connection is stable and smooth.
