Alarm Systems
Dependable email for your alarm & access systems
Zone triggers, arm and disarm events and low-battery warnings delivered reliably, so the record of what happened is always complete.
The problem
What goes wrong with alarm systems email
Intrusion panels, access controllers and life-safety systems use email to report zone triggers, arm and disarm activity, forced doors and failing backup batteries. This is a compliance and accountability record as much as a notification — a missing arm-away email can turn an incident investigation into guesswork.
Alarm panels are typically installed once and left untouched for years, so an email configuration that quietly stops working can go unnoticed for a very long time.
Why conventional SMTP setups fail
The internet moved on — the firmware didn’t
Alarm hardware has long firmware lifecycles, and the SMTP code inside it rarely keeps pace with the mail world around it. Panels built around basic authentication simply stop delivering once Gmail or Microsoft 365 withdraw it.
Many panels are wired to lines where outbound SMTP ports are blocked, and their dated TLS stacks fail the handshake against modern servers. Because a panel offers no delivery visibility, an alarm email can be failing for months with nobody aware until an event is needed and isn’t there.
How DeviceSMTP solves it
One gateway purpose-built for alarm systems
A stable relay endpoint
A single, long-lived hostname that outlasts provider changes — ideal for panels you configure once and rarely revisit.
TLS & SSL to match the firmware
Match the panel’s capabilities with STARTTLS on 587/2525 or implicit SSL on 465 for an encrypted link.
Per-panel credentials & labels
Label each controller, for example “Panel — Main entrance”, and manage its access independently of other sites.
Delivery logs & bounce monitoring
Keep a verifiable record that each zone trigger and arm/disarm email was delivered — invaluable for audits and incident review.
Example notifications
The kind of mail these devices send
- Zone triggered and intrusion-alarm events
- Arm, disarm and bypass activity
- Forced-door and door-held-open alerts
- Backup-battery low and power-loss warnings
- Tamper and enclosure-open notifications
- Scheduled test-signal and self-check reports
