Protecting facilities lacking electricity
With an alternative 6 V⎓ power supply unit, an Ajax hub or a range extender can operate from an external battery for years without being connected to the facility’s power grid. This setup is ideal for protecting buildings in critical condition, construction sites, or abandoned properties from burglars, vandals, and unauthorised occupation.
In Warehouses, Building Sites etc:
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.
In Campervans and Caravans:
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.
On Yachts:
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.
