Wireless signal blockers are devices designed to block various frequencies of wireless signals, including mobile phone signals, Wi-Fi signals, Bluetooth signals, remote control signals, wireless video transmission signals, and wireless data transmission signals. However, there is a common question from customers regarding whether these wireless signal blockers can also block wired cameras that transmit video signals through video cables. This article aims to clarify the limitations of wireless signal blockers and their effectiveness in blocking wired cameras.
Limitations of Wireless Signal Blockers:
Unfortunately, wireless signal blockers can only block wireless signals and do not include wired signals transmitted through cables. In the current market, various types of cameras have two main methods of video signal transmission: wired and wireless. When using wired transmission, the video signal is transmitted through video cables, and the interference signals emitted by wireless signal blockers do not affect or block the video signals in the cable.
Effectiveness of Wireless Signal Blockers on Wired Cameras:
However, there is a special scenario where wireless signal blockers can have some interference on wired cameras. This occurs when the video cable of the camera is very close to or in direct contact with the transmitting antenna of the wireless signal blocker. If the video cable lacks shielding materials or the protective layer of the cable lacks anti-interference materials, the video signal in the cable will be severely disrupted. As a result, the receiving end of the video signal may not receive a clear and normal image.
In conclusion, wireless signal blockers are primarily designed to block wireless signals, including mobile phone signals, Wi-Fi signals, Bluetooth signals, remote control signals, wireless video transmission signals, and wireless data transmission signals. However, they do not have the capability to block wired signals transmitted through cables. It is important for customers to understand the limitations of wireless signal blockers and their effectiveness in blocking wired cameras. When using wired cameras, interference from wireless signal blockers can only occur if the video cable is in close proximity to the transmitting antenna without proper shielding or anti-interference materials.
