For commercial properties and high-net-worth homes, a bell ringing on the wall isn’t enough. The alarm panel must communicate instantly with a professional Alarm Receiving Centre (ARC), who can dispatch police or keyholders.
To achieve this level of security (often required for insurance compliance, such as Grade 2 or Grade 3 alarms), professional installers mandate multi-network SIMs for alarm monitoring.
Dual-Path Signalling and Redundancy
High-security alarms use “Dual-Path” signalling. The primary path is usually a hardwired broadband connection. The secondary path is a cellular connection (4G/GSM).
If an intruder cuts the broadband wire outside the building, the alarm instantly fails over to the cellular path to send the SOS. However, if the cellular path relies on a standard, single-network SIM, the system is highly vulnerable. If the local mast happens to be congested or offline when the wire is cut, the signal fails.
The Multi-Network Guarantee
Anywhere SIM provides the ultimate cellular redundancy for Dual-Path signalling.
- Four Networks in One: Our unsteered M2M SIMs scan EE, O2, Vodafone, and Three. If the primary cellular network drops, the SIM automatically switches to a backup network, ensuring the ARC receives the intrusion alert.
- Secure Private APN: To meet strict security and insurance regulations, alarm data must not travel over the public, interceptable internet. We provide secure routing via Private APNs, ensuring the panel’s communication with the ARC is entirely encrypted and secure.
- M2M Reliability: Our industrial-grade SIMs are exempt from inactivity deactivations, ensuring the cellular backup path is always active and ready, even if it hasn’t been used for months.
