Q: No picture with power on
A:
It may result from abnormal power supply. Please check if the power supply
voltage and its polarity are correct. Besides, please confirm if wires connection
and monitors are normal.
Q: Unclear image output
A: It is caused by incomplete adjustment of the lens back focus. Loose the fixed
screw of the lens until it turns clear. If not, please check if the lens is in good
condition, or the lens surface and sensor surface exits foreign objects. If exits, it
can be wiped by degreasing cotton swab or lens paper.
Q: Horizontal interference fringes on image
A: This phenomenon is generally caused by too strong hum bar of power supply,
which needs to be filtered out. It may also be related to the used monitor or
peripheral devices.
Q: Constantly change of the ground color of image
A: This phenomenon is caused by color scrolling, which is mainly due to alternating
electromagnetic field of fluorescent lamp, and the inherent phenomenon of
camera. It can be weakened with two methods: one is to reduce the usage
of fluorescent lamp. The other is to enlarge the distance with the camera. To
overcome it thoroughly, please select LL synchronization camera.
