Use Ajax in premises lacking electricity or having an unstable power supply. A 12 V power supply unit allows connecting hubs and radio signal extenders to low-voltage networks or use a portable battery.
Ajax protects your home, even if it goes on wheels. Connect the hub to a car or portable battery, and let the security system travel with you.
Insert a SIM card and connect the hub to the on-board network or battery so that Ajax always guards your boat at the pier.
