Welcome
CallOnAlarm® is a SaaS notification platform dedicated to delivering automated phone calls the moment an alert is triggered. While its primary mission is voice-based alerting, it also provides technical updates via email—all according to your specific configuration. You define exactly when to trigger a call and which technical events require an email, keeping you in full control of your notification logic.
⚙️ Your rules → 📞 Urgent Call and/or 📧 Technical Email
Important Notice: The platform currently supports outbound calls to European phone numbers only. The service is therefore intended for use with European numbers. Users located outside Europe who wish to use the service must obtain and maintain a compliant, non-premium European phone number from an authorized telecommunications provider. It is the user’s responsibility to ensure compliance with all applicable local laws and telecommunications regulations.

Three Ways to Trigger Alerts
Connect Your Alarm Panel
Connect your existing alarm system (Hikvision, Dahua, Vesta, Ajax, and any SIA DC-09 compatible panel) to CallOnAlarm. When an intrusion, fire, panic, or critical event is detected, we call your contacts.
Use Our Public API
Build your own alert system. Our API allows any device, application, or script to trigger phone calls. Monitor servers, IoT sensors, industrial equipment, cryptocurrency prices, or anything you can imagine.
Use cases:
🖥️ Server down? Get called immediately
🌡️ Temperature sensor exceeds threshold? Alert triggered
📈 Crypto price hits your target? Phone rings
🏭 Industrial equipment failure? Instant notification
🔔 Any custom event you define
Build Your Own Compatible Hardware
Build your own compatible device. Use any microcontroller (such as ESP32, Arduino, or similar) and integrate our simplified SIA protocol implementation to connect virtually any alarm-generating system (NVRs, sensors, home automation devices, industrial equipment, etc.) to the CallOnAlarm platform.
