IoT SIM for alarms and Alarm Receiving Centers
Short answer
An IoT SIM for alarms keeps the panel reporting to the Alarm Receiving Center (ARC) even when one operator goes down: it switches automatically across 2G/4G/5G networks from different operators, supports LTE-M for long-battery detectors, and lets the ARC reach the panel via static IP without opening ports on the client side. The difference between an alarm that reports and one that doesn't.
Why a regular SIM doesn't cut it for alarms
Consumer SIMs are single-operator: when that network drops, the alarm stops talking. For critical systems that's unacceptable. A security-focused IoT SIM assumes the network can fail and fails over automatically, keeps the IP stable for the ARC, and is observable from your system (heartbeat, last seen, per-SIM signal strength).
- 2G→4G→5G failover on network drop
- Optional static IP for ARC, no client-side port forwarding
- LTE-M and NB-IoT for low-power sensors
- Heartbeat and supervision via REST API
Typical security use cases
Residential and commercial alarms connected to an ARC, perimeter intrusion systems, electronic access control, portable panic devices, video-verification with connected NVR, and critical infrastructure monitoring (substations, water tanks, repeaters). All share the same profile: low traffic, mandatory low latency, availability as the main requirement.
Compatible with M2M panels
Works with the usual brands (Honeywell, DSC, Paradox, Pyronix, Texecom, Ajax, Risco) that accept a standard 2FF/3FF SIM. For autonomous sensors (smoke detectors, personal panic) we work with LTE-M and NB-IoT modules with multi-year battery life. No special firmware: configure the APN and you're live.
Trial SIMs to integrate with your ARC
Tell us which panel and which ARC. We ship pre-configured trial SIMs with the right APN (and static IP if needed) so you validate the end-to-end communication scenario before migrating your installed base.
Frequently asked questions
How much does an alarm SIM cost?+
Plans from €1-3/SIM/month depending on plan and volume, with billing aggregated across the fleet. Premiums apply for LTE-M support, static IP, or dedicated private APN.
Does it survive 2G sunset in some countries?+
Yes. The SIM has a multi-tech profile: if a country shuts down 2G (Switzerland, Netherlands…), the SIM keeps working via 4G/LTE-M there while preserving 2G in countries where it's still on.
How does it integrate with my ARC?+
If the ARC exposes a public-IP endpoint, SIMs talk to it directly. If you need the ARC to reach the panel from outside, per-SIM static IP (public or private) solves that. We help you set up the scenario.
Remote SIM-state monitoring?+
Yes. Portal and REST API show last seen, signal strength, and bytes sent per SIM. You can trigger alarms if a SIM hasn't been seen in X hours — useful for detecting uninstalled or vandalized panels.
