Camera interference generator - an effective means of adversarial surveillance
With the increasing popularity of closed-circuit television cameras, they can now be seen in almost every corner. No matter where you go, in any public place, you can be 95% sure that the surveillance camera's lens is watching you. When the situation where people's private lives may become the property of strangers is created, it is necessary to find ways to prevent this threat. For closed-circuit television cameras, we are talking about interfering with video signals. After all, with the development of technology, surveillance cameras can reach incredibly small sizes, making the process of detecting them very complex.
Due to the rapid development of digital technology in the field of video signal transmission, video surveillance has reached a new level of quality. Nowadays, for video surveillance of specific objects, a phone, tablet, or laptop is sufficient, and all signals that occur in front of the camera will be presented to you. Attackers conducting surveillance can also do the same.
Therefore, the best way to protect privacy is to use simple devices, known as' signal jammer'. Similar devices are used to block cellular and wireless internet connections, but can also be used to interfere with video signals. All you need to do is tune the generator to the desired frequency.
To provide an overview of the entire process of video shooting, we will briefly introduce all the components:
This is the system recorded from the connected surveillance camera. Information is stored on a built-in hard drive and can also be written to removable media. The size of hard disk memory depends on the uninterrupted recording time. Usually, it ranges from 5 to 20 days.
There are two types of cameras: analog and digital. Basically, all devices have different technical data and operating methods. These can be indoor cameras that operate at specific temperatures and are very sensitive to their reduction. We also produce equipment that can withstand significant atmospheric impacts and temperature changes, and such cameras are typically placed on the streets.
They are divided into three types: transformer type, pulse type, and uninterrupted type. The current can be either AC or DC. Choosing a suitable power supply is very important as it can avoid technical issues during the entire system operation process.
Almost all video surveillance systems are designed for 24/7 operation. For this reason, monitors are known for their high image quality, ability to operate continuously for extended periods of time, and are completely safe to use.
The generator will prevent the signal from being transmitted from the camera to the connected device, thereby generating interference at the root of the signal itself. As a result, the image from the camera cannot be displayed at all, or serious distortion may occur during display due to interference caused by obstructions. This will depend on the power of the equipment used.
There are several types of devices for suppressing video signals:
Mobile;
Stationary;
heavy burden.
The fixed signal jammer operates through a 220V network and only produces local effects at pre-selected locations. But at the same time, they can have a considerable coverage radius, which directly depends on the power of the device.
Portable generators are very convenient to use because they can be carried around without the need to connect to the network. Portable generators can operate completely autonomously and can definitely run anywhere, making them very suitable for use in certain situations, such as overseas, where it is uncertain whether video surveillance is being carried out.
The rarest type of generator is a heavy-duty generator. Dedicated to large-scale facilities such as prisons and production workshops.
