Why the image of one of the camera is blurred?

There could be four reasons to lead to the problem:
1.Irradiation distance is too close, pls try to adjust the angle.


2.The lens may be blur, you need to disassemble the camera and adjust the focus.


3.Maybe the cable get problem, pls use another working cable and connect the camera to another interface to test.


4.Pls revise the output resolution according to the resolution the minitor supports.

Why image seems to be blurry at night for APP, but TV not?

It is normal, because the transmission of the resolution for APP monitoring is CIF, the frame rate is 6fps, and it is 2CH D1+6CH CIF/8CH 960H on TV real time monitoring, the frame rate is 25fps, then it is normal to see the image seems to be blurry at night vision.

Reason why there isn't output video of the camera when connecting to TV

1. The cable may be damaged,pls change a cable to test it.


2. Power supply may has problem ,pls replace a new power supply for it.


3. If the problem can not be solved,pls contact custom service.
