No monthly fees or contracts with security companies; you simply pay your mobile phone provider. Insert a GSM SIM card (not included) to make calls and send alarms. Alternatively, you can use the Wi-Fi function. The complete system consists of a fully programmable main unit and wireless sensors. Please read the user manual carefully before use. Network support: The alarm control panel has a built-in GSM module that supports GSM SIM cards. T-Mobile SIM cards are compatible with our system (this alarm system does not include a GSM SIM card). When a sensor is triggered, the alarm control panel makes a call or sends an alarm message to the pre-defined emergency number. Loud alarm and fast help: In an emergency, children and elderly people in the house can press the emergency button on the remote control. This will trigger all alarms and send emergency calls and messages to other family members so they can get help in time. Six pre-set emergency number groups are supported. When an alarm is triggered, the control unit automatically dials the preset number. Defense zone support: Allows up to 99 wireless and 8 wired defense zones, 5 programmable arm/disarm groups; 2 wired sirens for homes of different sizes to meet your needs; Easy self-installation and assembly without tools, plug-and-play installation. INTEGRATED BATTERY: This system continues to function perfectly even if the wires are cut or the power is out. You don't have to worry about intruders entering your home during a power outage. Before use, please turn on the control unit first and then connect the power adapter. The battery will automatically send a low battery warning. It will also display notifications about power outages and power restoration.
