1. Mature technology and high stability. One line communication monitoring project transmission is 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 carrier high-frequency transmission mode 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 and high cable utilization.

5. The construction is simple, the maintenance is convenient, and the material cost and construction cost are greatly saved.

6. Simple expansion (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 and fully compatible with monitoring, 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.
