LTE / 4G / 5G Remote Alarm & Monitoring System
Monitor temperature, humidity and power status remotely with cellular alarm devices. Supported models can send SMS alerts over compatible mobile networks. Network coverage, SIM plans and messaging charges depend on the device and local service provider.

Overview
EcoXplore provide GSM alarms monitoring devices can be installed with any control panel capable of generating an output and used over any standard mobile network, anywhere in the world. The GSM device uses wireless communication through the worldwide GSM, via text messages. It allows the user to remotely access up to date information on demand, or to receive an update at a pre-defined time, or simply to be sent alarm messages when they occur. The SIM card for the system is provided and controlled by the user
All devices can be handled in EcoXplore’s monitoring solutions, are supported by our technical team and provide the complete solution for wireless alarm communications.
The GSM SMS 3G Environment Alarm is special for remotely monitoring onsite temperature, humidity, power status through wireless GSM/3G Network. When the temperature, humidity, power voltage exceed high threshold or low threshold value, will send SMS alert to up to 10 preset mobile phone immediately.
Just dial from Authorized User number, the GSM 3G Environment Alarm will reject at the first “Ring”, no communication cost, and then return the current temperature, humidity, power status or voltage. Moreover, it can report onsite environment interval or daily.

The GSM 3G Environment Alarm can be used for solar power monitoring, DC power voltage monitoring, temperature monitoring, humidity monitoring, Class Room, Public Room, Waiting Room, Hospital, Stations, Fresh Food Warehouse, Office, Meeting Room, Laboratory, Library and anywhere that need monitoring temperature or control temperature in expected range.

Frequently Asked Questions
When do GSM alarms make sense versus IP-based monitoring?
GSM alarm devices are the right choice where wired IP connectivity is unavailable, unreliable, or prohibitively expensive: remote sites, mobile assets, equipment on isolated networks, or sites where the primary network would itself fail in an outage scenario. SMS over GSM uses an independent path, so alarms still escape when the IP network is down.
What kinds of inputs can a GSM alarm device monitor?
Volt-free contact closures from any control panel (BMS, fire alarm, security, generator status), analogue temperature and humidity sensors, mains power presence, and door contacts. Multi-channel devices typically support 4 to 16 monitored inputs per unit.
Who supplies the SIM card and pays for messages?
The SIM card and mobile plan are owned by the user, allowing them to choose carrier, tariff, and roaming policy. Pay-as-you-go SIMs are common for low-event sites; monthly plans suit sites with frequent alerts or two-way control. Multi-network SIMs improve resilience in areas with patchy coverage.
Can the device be controlled remotely?
Yes. Two-way devices accept SMS commands from pre-authorised numbers to trigger output relays (reset alarms, switch equipment, open gates) and to request immediate status updates between scheduled reports.
