Everyone must have seen such a movie scene. A hacker successfully invaded the security surveillance system of a certain building and implanted the preset video footage into the surveillance system, so that the security guard saw the video footage that was always normal. .
Of course, hacking in reality is not so easy, and we do not recommend that you really follow suit. After all, this kind of behavior will bring great losses to your life. However, when this behavior is used as an experiment and successfully implemented, it will inevitably have great significance for the development of the surveillance industry and the subsequent security framework.
So let’s try to implement the picture mentioned at the beginning. If we want to replace the original picture, then there must be a device that can simulate the camera, and then change the channel configuration of the NVR to change the channel access of the picture to the corresponding simulator’s Screen address, currently the leading NVR devices on the market basically support RTSP or GB28181 access.
Since RTSP protocol and GB28181 protocol are mentioned here, TSINGSEE Qingxi Video currently has video streaming platforms EasyNVR and EasyGBS corresponding to these two protocols, which can be connected to front-end equipment such as cameras or NVR.
The analog camera we are talking about is a front-end video capture device. The output of the analog camera is an analog video signal. The encoder can convert the analog video signal generated by the video capture device into a digital signal, and then store it in the computer. The video signal captured by the analog camera must be converted into a digital mode by a specific video capture card, and compressed before it can be converted to a computer for use.
Similarly, for security development, we often lack equipment to debug security programs. Then, if there is a smart and lightweight camera simulator to simulate RTSP stream, GB28181 equipment, it is technical in terms of working time and cost. A small step and a big step for agile work. In the future, TSINGSEE Qingxi Video will also fully develop more equipment or service platforms to further open up more possibilities and pave the way for the future of the video intelligent security industry.
