4.0 FAQ's

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. Also you will need to confirm if the wire
connections and monitors are normal.
Q: Unclear image output
A: It is caused by incomplete adjustment of the lens back focus. Loosen 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 is clear. If not, please wipe with a
degreasing cotton swab or lens paper.
Q: Horizontal interference fringes on image
A: This is generally caused by too strong of a 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 is caused by colour 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 synchronisation camera.
