With the development of the domestic camera market, the demand for ffc flexible cables used in security cameras is also expanding. But consumers will also find that not every brand of camera can ensure clear imaging. This is because the unavoidable electromagnetic induction phenomenon will occur between the conductors of the security monitoring ffc cable after power-on. Excessively strong electromagnetic will cause signal interference and other problems. Therefore, in order to avoid the problems of blurry picture, snow, and pitting, it is necessary to optimize the selection and arrangement of ffc cables. The specific solutions are as follows:
(1) Stagger the power line and signal line of the ffc cable of the camera.
In the security camera, the power line is strong current, and the communication line is weak current. Strong electricity will directly interfere with weak electricity communication signals. Therefore, the two should be arranged in zones. Avoid interference in signal transmission.
(2) Increase the film thickness of the ffc cable of the camera.
The thickness of the ffc cable film is directly related to the impedance value of the cable. Generally speaking, a thicker film can provide a higher resistance value and effectively reduce the signal interference between the camera cables.
(3) Perform EMI treatment on the ffc cable of the camera.
If the camera ffc cable does not achieve the ideal state of the surveillance image through the above two improvements, you can try to perform EMI processing on the ffc cable. That is, a layer of copper foil is pasted on one or both sides of the ffc cable. EMI treatment allows interfering electrons to be evenly dispersed through the copper foil to resolve the interference, so that the monitoring image is not disturbed and clearer.
