Regarding for above issue,we have tried best and also provided the best solution for this customer,Mr Simon.Both sides have solved the problem with the satified results 5 monthes agao.
The problem: Mr Simon bought some cameras from us in January,2014.After received the goods and feedback the problem for us,we follow up it timely.He mentioned that some IMX138+FH8520 CCD boards which are couldn't work at night,he asked send back these CCD boards and replaced all new for him.
After received CCD boards ,Cantonk Technical Support Engineer tested and found these cameras are wihtout IR,so they had not night vision and wouldn't have good effort on the low illumination .But during the day,all of these CCD boards were work very well.Mr Simon also clearly this issue.
However,we take attention into customer's requirement,agreed to replace all new CCD boards for Mr Simon.Then both of us solved the problem with satified results.
