Smart Home Alarm System LTE-400

With WiFi & 4G LTE dual protection, the LTE-400 is an ideal system for home security. In the unfortunate event of a break-in, fire or fluid overflow, it sounds a loud siren on site to deter would-be intruders and sends app push notifications to up to 10 pre-authorised users. When a regular-sized, compatible 4G/3G SIM card is inserted, and your home WiFi network happens to be down, the smart hub also has a cellular connection* as back-up to send you app push and email notifications as well as SMS text messages and phone calls.
*In the case of a power outage and the cellular network in your neighborhood is still working, the LTE-400 will continue to protect your property and family for 4-5 hours on standby.
