Will the camera signal be blocked?

Faced with increasing security requirements, users have invented a series of products to protect our security. The camera is an important tool installed in various occasions to monitor every movement of the population. However, our private information is also collected. Especially with the emergence of spy cameras on the market, people’s privacy is easy to be photographed, which is extremely harmful to our privacy. So what should we do to avoid being caught by the camera? It is possible to use signal jammer.

First of all, the answer is yes. Simply put, as long as we cannot prevent the camera from shooting to us or prevent the camera from transmitting captured information, we will be interfered with or protect the camera. However, the types and styles of cameras are also diverse. It can be mainly divided into cameras connected by cables and cameras that use wireless technologies such as wifi, 3G/4G or spread spectrum radio to transmit signals.

To interfere with a wired camera, you must hack into the other party’s computer network to prevent the camera from working properly. This requires another skill, which is not detailed here.

Below we mainly explain why the camera equipment that uses wireless technology to transmit signals is protected by us. Wireless transmission technology is to use a certain frequency to send signals, and then use the corresponding equipment to receive these signals, you can get the image information captured by the camera. What we need to do is to intercept the transmitting frequency used by the other party and transmit the signal of the corresponding frequency, thereby interfering with the normal operation of the camera equipment. As mentioned above, the signals used by wireless cameras mainly include wifi, 3G/4G and broad-spectrum radio.

Wifi signals include wifi2.4G, wifi5.8G and 3G/4G signals are the signal frequency bands used by our mobile phones. Radio equipment mainly transmits information in the 400 MHz range. It is easier to find and acquire interfering devices on some frequencies than on others. For example, there are a large number of ordinary radios that can broadcast in the 400 MHz band, so it is easy to find a shelf that can block these frequencies. Wireless security providers usually take steps to protect you from interference attacks. It uses a proprietary algorithm to separate accidental RF interference from targeted interference attacks. With the right equipment and the right technology,

We need to list all the frequencies used for transmission and conduct targeted interference. Any system that receives a wireless signal of a specific frequency may be overwhelmed by a stronger signal on the same frequency, and eventually interfere with and shield the camera equipment.
