CSL provides Critical Connectivity for M2M devices in market sectors where there is a threat to life or property. Our tried and tested platform, connectivity and managed SIMs ensure your devices stay connected when it matters most. We pride ourselves on the experience we have gained in the electronic security industry which demands always-on connectivity and 24/7 support.

Our current alarm signalling devices facilitate the reliable delivery of alarm signals via any available GPRS/GSM network and/or a telephone or IP path from the protected premises to the Alarm Receiving Centre. The CSL range includes the best selling single and dual path DualCom GradeShift range and award winning DualCom DigiAir for the Fire & Security industry. We also offer our proven track record in the delivery of Critical Connectivity to the residential care industry with DualCom SafeLink and SmartAccess.

Our WorldSIM is free of Network Steering to optimise your device and you won’t experience the delays caused when a SIM tries to return to its home network. WorldSIM uses a patented algorithm to select the strongest network and eliminate downtime before it becomes a problem for your customer. It offers true roaming, fixed costs and full control via a handy user portal. It is supplied as standard in all our products and many manufacturers now choose our WorldSIM for use inside their own M2M devices.

Our products and services are powered by the Gemini Platform which provides a fully resilient and redundant network for the safe and secure transfer of critical data. Gemini checks the entire signalling route every minute providing the highest levels of reliability.
