The Critical Value of Edge Recording Redundancy

The Critical Value of Edge Recording Redundancy

29th May 2025

Why Choosing the Right VMS and Cameras Matters

Across Southeast Asia’s mining, energy, and infrastructure sectors, security systems are often deployed in challenging environments where network connectivity is intermittent at best. When footage can’t afford to be lost due to a connection drop, edge recording redundancy becomes essential.

At Ruswin, we design and implement CCTV systems that guarantee no gaps in video retention, even during server or network outages. This is made possible by combining the right Video Management System (VMS) with reliable cameras like those from Axis, Hanwha, and Avigilon, configured to record to onboard SD cards and synchronise footage when the connection is restored.


What Is Edge Recording Redundancy?

Edge recording allows each CCTV camera to record locally to an internal SD card during network or server outages. When the connection is re-established, the VMS automatically retrieves the footage and inserts it into the main archive, preserving timelines, motion events, and metadata.

This removes the need for manual data recovery or on-site interventions and ensures continuous evidence capture even in the most remote or mission-critical environments.


Why Your VMS Matters: Enterprise-Grade Support Is Key

Edge redundancy is only as effective as the VMS platform managing it. Many systems may record to SD cards, but only a few can automatically detect outages, retrieve footage, and re-integrate it into the archive without data loss or manual work.

Top VMS platforms with reliable edge sync support:

VMS Platform Edge Sync Support Timeline Merge Best Use Case
Genetec Security Center Yes Yes Large-scale enterprise, high-security and compliance-driven sites
Milestone XProtect Yes Yes Customisable, multi-site deployments with open integration needs
Avigilon Control Center (ACC) Partial Partial  Unified Avigilon environments and fixed infrastructure
Nx Witness Yes Yes Lightweight systems, small to medium-scale commercial deployments

Why Genetec and Milestone Stand Out:

  • Genetec Security Center offers advanced metadata handling, alarm/event backfill, and granular policy control, ideal for critical infrastructure and government facilities.

  • Milestone XProtect delivers flexibility and openness, with tight SDK integrations to Axis and Hanwha, making it suitable for distributed, multi-vendor environments.

  • Nx Witness is a capable solution for smaller sites or customers seeking rapid deployment, but lacks the enterprise-grade depth and policy sophistication of Genetec and Milestone.

Camera Compatibility: Axis, Hanwha, and Avigilon

To enable true edge recording redundancy, the camera must support:

  • Internal SD card recording

  • Event-triggered capture

  • Firmware support for edge sync APIs

Ruswin recommends:

  • Axis Communications: Excellent integration with all major VMS platforms

  • Hanwha Vision (Wisenet): Advanced edge features and strong analytics

These manufacturers are tested and supported for mission-critical deployments in mining, defence, ports, and high-value infrastructure across Southeast Asia.


Recommended SD Card Specification for Edge Recording

Specification Recommendation
Type Industrial-grade SDXC or microSDXC
Capacity 128 GB to 256 GB per camera (2–5 days retention)
Endurance High Endurance or pSLC-grade flash
Speed Class Class 10 / UHS-I or higher
Brands SanDisk Industrial, Samsung Pro Endurance, Transcend High Endurance

Larger capacity cards (e.g. 512 GB) can be used in high-traffic areas or where prolonged outages may occur.


Where Edge Recording Redundancy Makes a Difference

Edge redundancy is especially critical for:

  • Remote mines and exploration camps

  • Energy and utility substations

  • Construction zones and mobile security units

  • Ports, logistics, and offshore platforms

  • Any site relying on 4G, satellite, or unreliable backhaul


Ruswin’s Edge-Ready Implementation Standard

Ruswin treats edge recording not as an optional feature—but as a foundational standard for surveillance system resilience. We deploy:

  • SD card health monitoring and life cycle tracking

  • Automated backfill validation and VMS integration

  • Camera/VMS pairings tailored to customer infrastructure

  • Pre-tested disconnect/reconnect recovery workflows

We have successfully delivered edge-enabled systems for some of the most demanding mining and infrastructure projects across Indonesia and Southeast Asia.


Conclusion

If your site can't afford to lose footage—even when the internet goes down—edge recording with automatic backfill is essential. Selecting a VMS platform like Genetec Security Center or Milestone XProtect, paired with proven cameras and SD card hardware, gives your organisation peace of mind, resilience, and regulatory compliance.

Whether you're working from a jungle in Kalimantan, a mine in Sulawesi, or a remote energy facility—Ruswin delivers surveillance that never stops recording.
