Why you need double-shielded cables not signal shielded cables for DVR system?

Using a double-shielded cable instead of a single shielded cable for a DVR (Digital Video Recorder) system provides additional protection against electromagnetic interference (EMI) and radio frequency interference (RFI), which helps to ensure a high-quality and reliable video recording and monitoring experience by minimizing the impact of external interference and maintaining signal integrity.

Here are some reasons why a double-shielded cable is preferred for DVR systems:

1. Enhanced Protection: Double-shielded cables have an additional layer of shielding compared to single-shielded cables. This extra shielding helps to minimize interference from external sources, such as power cables, radio signals, or other electronic devices, which can degrade the quality of the video signals in a DVR system.

2. Improved Signal Quality: By reducing the effects of EMI and RFI, double-shielded cables help maintain the integrity of the video signals transmitted within the DVR system. This results in clearer and more stable video recordings without disruptions or distortions caused by external interference.

3. Longer Transmission Distances: Double-shielded cables are more effective at preventing signal degradation over longer cable runs. In a DVR system where video signals may need to travel significant distances between cameras and the recorder, using a double-shielded cable can help maintain signal quality and reduce the risk of signal loss.

4. Compliance and Reliability: Many DVR system installations require compliance with industry standards for signal quality and interference protection. Using a double-shielded cable ensures that the system meets these standards and provides a reliable and robust signal transmission environment.

5. Fire resistant: In DVR systems, where surveillance and security are paramount, maintaining communication between cameras, recorders, and monitoring stations is crucial. Fire-resistant cables ensure that the communication infrastructure remains operational during a fire, allowing for continued surveillance and monitoring capabilities.
