Key specs explained for D1D9
Connectivity: 4G, Wi-Fi
This system supports two distinct network types. You can connect via standard Wi-Fi for local control. The 4G option allows the system to work without a home internet router, using cellular data instead. This dual approach ensures you receive alerts even if your Wi-Fi goes down. It is useful for homes with unstable internet or for remote properties. When comparing security kits, check if both options are included for true reliability.

When shopping, compare the number of included sensors to ensure you have enough for all your doors and windows without needing immediate add-ons.
Width: 6.2 inches
The main control panel measures 6.2 inches in width. This dimension indicates a compact footprint for the central hub. It can fit on a shelf or desk without taking up excessive space.

This measurement helps you determine if the device fits comfortably in your chosen spot.
Length: 10.5 inches
The device is 10.5 inches long. This length provides a stable base for the control unit. It suggests a rectangular shape that fits standard desk or shelf dimensions. The length helps distribute the internal components securely. When comparing alarm systems, check the length to ensure it does not extend too far into your workspace.
