1、 Mature technology and high stability

One line communication monitoring transmission is developed based on cable TV technology. Cable TV technology has been applied in China for 20 or 30 years, and its stability and reliability are obvious to all.

2、 Long transmission distance and good image definition

The image quality reaches the national standard above level 4.5.

3、 Strong anti-interference and wide application

The monitoring project adopts carrier high-frequency transmission mode, which can effectively suppress common mode interference and electromagnetic interference, and ensure image quality even in harsh electromagnetic environments such as power plants and coal mines.

4、 Simple wiring

High cable utilization.

5、 Simple construction and convenient maintenance

Save a lot of material cost and construction cost.

6、 Simple expansion

There is no need to rewire, just input a new signal.

7、 Data modulation and bidirectional transmission

FSK data modulation technology is adopted for the control signal, which is transmitted Bi directionally in the same cable as the video signal returned by the camera. If modulation is adopted for the control signal, which is stable and reliable.

8、 Powerful

Fully compatible with monitoring engineering, alarm, broadcasting and multi-functional two-way transmission platform.

9、 Easy access to electricity
The power supply mode adopts AC220V AC power supply or ac60v centralized power supply from the machine room.
