Display GSM Telemetry

Have your important equipment monitored by our GSM telemetry systems and have SMS alarms sent straight to your cellphone or PC based system.

Units are supplied as standard from 2-inputs and 1-output thro to 10-inputs and 9-outputs.

Inputs can be digital, contact closure or analog (5x2 only) and the outputs we can interface for you to control, ON/OFF or pulsed (timed), any electrical device.

Imagine having a temperature alarm in your server room sent to your cellphone and have the facility to switch ON a standby air-conditioner. Or a low level alarm on your irrigation dam and you can turn ON your pump - even if your system is in Capetown and you are in London !
