Reliable connectivity is a fundamental requirement in modern security and surveillance deployments, especially for IP cameras, edge video systems, and connected monitoring infrastructure operating across diverse or remote locations.
Security integrators and OEMs increasingly use cellular connectivity in environments where Wi-Fi or Ethernet are impractical or where permanent infrastructure is too costly to deploy. But simply inserting a SIM and hoping for stable performance isn’t enough.
Designing connectivity into the system from the start helps ensure uptime, performance consistency, and compliance across regions.
Key Connectivity Challenges in Security and Surveillance
Security and surveillance deployments depend on uninterrupted connectivity, yet many projects still run into recurring and costly challenges once devices move from lab to field. Common issues include:
Permanent roaming restrictions in countries such as Brazil, Turkey, and Australia, which can prevent devices using roaming-based SIMs from registering on local networks.
Throttling or degraded performance can occur when devices connect as roamers on visited networks, reducing video quality or interrupting alerts.
Lack of local breakout causing higher latency and inconsistent streaming performance when data is routed internationally instead of within-region.
Manual SIM swaps required to resolve connectivity problems or change carriers in the field, adding unnecessary truck rolls and deployment delays.
Operational complexity created by fragmented connectivity management, multiple SIM SKUs for different regions, varied billing cycles and contracts, and separate management platforms for each carrier.
Paying for unused SIMs during manufacturing, staging, or delayed deployment cycles. In many models, billing starts at SIM shipment or installation, regardless of when the device is activated in the field, adding avoidable cost to large-scale rollouts.
Limitations of Wi-Fi-based systems can introduce added infrastructure burden. Many deployments lack access to stable on-site networks or require costly installation of access points and cabling. Wi-Fi coverage is often unreliable in outdoor or mobile environments, and public networks may pose security and performance risks.
Deployment complexity varies across urban and regional environments. In dense urban areas, interference and congestion can affect performance, while in rural or remote locations, network coverage and backhaul availability can be inconsistent or limited.
These challenges make it harder to deploy, scale, and manage connected devices efficiently, especially across multiple regions.
How Multi-Network SIM Technology Solves Real Deployment Challenges
Security and surveillance systems increasingly operate across varied geographies, network conditions, and regulatory environments. To maintain consistent performance, these systems require connectivity that is flexible, resilient, and adaptable over time.
Technologies like multi-IMSI and eUICC (SGP.32) were developed to address exactly these types of deployment realities. Unlike single-carrier or roaming-only SIMs, they enable devices to operate across multiple networks with greater control, improved uptime, and compliance with local requirements.
Multi-IMSI: Built for Network Resilience
Multi-IMSI SIMs store multiple network profiles on a single SIM and switch automatically between them based on predefined conditions such as signal strength or network failure.
In the context of security deployments, multi-IMSI supports:
- Autonomous failover across multiple carriers in a given country or region
- Connectivity in highly regulated markets where roaming is restricted
- Greater uptime in mobile, outdoor, or remote installations
It’s especially effective when fast, local decision-making is required, such as when a camera or gateway needs to reconnect immediately without backend delay or manual input.
eUICC (SGP.32): Designed for Lifecycle Control
The SGP.32 specification was introduced to simplify IoT deployments by improving how operator profiles are provisioned and managed remotely. eUICC allows SIM profiles to be downloaded, activated, or updated over the air, using centralized infrastructure.
SGP.32 offers several key advantages for long-term security deployments:
- Server-side control of SIM profiles without operator approval
- Deferred, bandwidth-efficient OTA switching for devices with limited uptime (e.g., NB-IoT, LPWAN)
- No reliance on SMS for provisioning
- Centralized fleet-wide management using SM-DP+
These features make eUICC especially useful for devices deployed in inaccessible locations or for projects where long-term profile flexibility is needed.
Hybrid Strategy: The Best of Both
Many modern deployments combine multi-IMSI and eUICC in a hybrid model. This enables:
- Fast, automatic switching between local networks via Multi-IMSI
- Long-term adaptability and provisioning control via SGP.32 eUICC
A single SIM strategy that balances responsiveness with lifecycle flexibility
