If the image from a video surveillance system is subject to interference, the following symptoms may appear:
The monitor screen displays black or white stripes scrolling up and down:
This phenomenon usually occurs due to interference from the 50Hz power frequency, often caused by improper grounding between the front-end equipment and the control center, which creates a potential difference that enters the video surveillance system, but can also be due to poor power performance of the equipment itself.
Noise appears on the monitor screen:
The main cause of such interference is signal attenuation on the transmission line and the coupling of high frequency interference.

This may be caused by the characteristic impedance of the video transmission line or between devices not being 75 ohms, and regular vertical stripe interference may also appear on the screen.
Diagonal interference, jitter interference, power interference:
These interferences may interfere with normal images in mild cases, or cause image distortion in severe cases. The causes of these failure phenomena are varied and complex, including poor quality of video transmission lines, especially poor shielding performance, or noise in the power supply system, and even strong interference sources around the video surveillance system. OHWOAI's home wireless solar-powered, battery-powered and POE-powered security cameras have IP67 waterproof and dustproof specifications, with a strong waterproof level, and no harmful effects even in bad weather such as rain and wind. They can be installed both outdoors and indoors. 5 million high-definition cameras linked to smartphones, improved heat dissipation and durability, and four times longer service life.
Broad pattern interference (single frequency interference):
This phenomenon is usually caused by a short circuit or break in the core wire and shield mesh of the video cable, or poor contact in the BNC connector.
When faced with video interference problems, we need to calmly analyze the type of interference, identify the potential causes, and make an effort to find a solution.
OHWOAI's wireless camera and recorder set is ranked at the top of the popular security camera set ranking. OHWOAI has always focused on providing high-quality surveillance solutions, ensuring that customers' video surveillance systems are interference-free and working to solve various interference problems.
