The main function of the wireless jammer is to shield the commonly used wireless signals of various frequency bands. The types of these wireless signals include mobile phone signals of all formats, WIFI signals, Bluetooth signals, remote control signals, wireless image transmission signals and wireless data transmission signals, etc. , but the question is coming, some customers will ask us, can the wireless jammer we produce shield wired cameras? That is, the kind of camera that transmits the video signal through the video cable.

The result is very sorry, what the wireless jammer can block is the wireless signal, and this does not include the wired signal transmitted through the cable. At present, when various cameras on the market are installed, their video signal transmission methods are roughly divided into two types, one is wired transmission and the other is wireless transmission. When using the wired transmission mode, the video signal transmission path is in the video cable, and the interference signal emitted by the wireless jammer has no interference and shielding effect on the video signal in the line. However, when the camera is wireless, such as through the WiFi2.4G or WiFi5.8G frequency band, or through the SIM card of the mobile phone, in the way of 4G or 5G data traffic, then in this form, our wireless jammer can It is very effective to shield and interfere with the transmission of video signals.

In addition, it needs to be added that there is actually another special scenario in which the wireless jammer can interfere with the wired camera to a certain extent. This is when the video cable of the camera is very close to or close to the transmitting antenna of the wireless jammer. The video cable has no shielding material or the protective layer of the cable lacks anti-jamming materials. At this time, the video signal in the video cable will be seriously interfered, which will also cause the remote video signal receiving end to receive normal and clear. Image.
