Unlocking Remote Access to CCTV Systems with Teltonika and Roaming Fixed IP SIM

In today’s interconnected world, remote access to CCTV systems is crucial for ensuring security and monitoring operations. However, conventional mobile broadband SIM cards often restrict this capability due to Carrier-Grade NAT (CGNAT), which assigns shared IP addresses to multiple users. This presents a challenge in establishing a direct link to the CCTV NVR from an external device. To overcome this obstacle and achieve seamless remote access, a combination of a Teltonika RUT200 industrial 4G router and a Roaming Fixed IP SIM card provides a robust and reliable solution.

The Limitations of Standard Mobile Broadband SIMs

Standard mobile broadband SIM cards implement CGNAT to conserve IP addresses and optimize network resources. While this approach is efficient for general internet access, it presents a significant barrier for remote communication with devices behind CGNAT, as their external IP addresses are concealed. This prevents external devices from establishing a direct connection to the CCTV NVR, making remote access impossible.

The Power of a Roaming Fixed IP SIM

A Roaming Fixed IP SIM offers a distinct advantage over standard mobile broadband SIMs by providing a dedicated, static IP address. This static IP address remains consistent, unlike the dynamic IP addresses assigned by standard SIMs. This consistency is essential for establishing a reliable and persistent connection to the CCTV NVR from any remote location.

Enabling Remote Access with the RUT200 and Roaming Fixed IP SIM

The setup process for enabling remote access to your CCTV NVR using the RUT200 and Roaming Fixed IP SIM is straightforward and can be completed in a few simple steps:

  1. Install the RUT200 router at the location of your CCTV NVR.
  2. Insert the Roaming Fixed IP SIM into the RUT200.
  3. Configure the RUT200’s network settings, including the APN provided by the SIM card provider.
  4. Access the CCTV NVR’s web interface using the RUT200’s public IP address, which can be obtained from the SIM card provider or from the RUT200’s web interface.


By combining the RUT200 industrial 4G router with a Roaming Fixed IP SIM, you can effectively eliminate the limitations of CGNAT and establish a direct, reliable, and secure connection to your CCTV NVR from anywhere in the world. This solution empowers you to monitor your security systems effectively and maintain peace of mind, regardless of your location.
