Smart Home System


With WiFi & 4G LTE dual protection, the H4-LTE 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 and email 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 neighbourhood is still working, the H4-LTE will continue to protect your property and family for 4-5 hours on standby.

Sharing Devices With Family Accounts

Everyone in the family can have their own account for free. The person who sets up the H4-LTE is the Main Administrator, who can then share device access with family accounts with two levels of access rights - Admin or User. Admin will have full access rights, except for re-sharing the devices, while User will only receive alerts and edit their own account information.
