What it does when the Wi-Fi drops is the specification that counts · review
Goliath uses 868 MHz two-way radio rather than Wi-Fi for its sensors, and includes a motion detector with a camera that takes a snapshot when triggered.
The conclusion The only two-way 868 MHz radio stated in this hub, with a camera that answers the question every false alarm asks.
Most consumer alarm kits put their sensors on Wi-Fi or on cheap 433 MHz radio. This one uses 868 MHz, two-way, and that is the reason to look at it.
The 868 MHz band is reserved in Europe for short-range devices with limited transmit time, so a sensor at the far end of a house is not competing with every router and doorbell in the street. It also travels further through masonry than 2.4 GHz.
Two-way is the more important half. The hub and each sensor confirm one another, so a sensor with a dead battery, a sensor that has been removed, or a sensor being jammed is reported. One-way systems treat silence as normal, which is exactly the state an intruder wants to produce.
A motion detector that photographs what triggered it. Every alarm eventually raises the same question — was that a person or the cat — and this answers it without you driving home.
It is also a camera in a room in your house, taking pictures when the system decides. Choose the room deliberately, and read what your own data protection authority says if anybody else lives there.
A proprietary radio means expansion comes from Goliath. That is the standard trade for a system that works reliably out of the box.
A house where false alarms have already become a problem.

Range and congestion. The 868 MHz band is reserved in Europe for short-range devices with limited transmit time, so it is not competing with every router, doorbell and microwave in the street, and it travels further through walls. The trade is that sensors must come from the same maker.
The hub and the sensor confirm each other, so a sensor that has gone flat, been removed or been jammed is noticed rather than silently absent. One-way systems assume silence means nothing happened, which is the assumption an intruder relies on.
It answers the question every alarm raises — what actually triggered it — and it means a camera inside your house that takes pictures when the system decides to. Place it accordingly, and think about which rooms it should not be in.
