What it does when the Wi-Fi drops is the specification that counts · review
A 22-piece kit: TUGARD states a hub with a 2.4-inch display, three motion detectors, ten door and window contacts and a 120 dB siren, with Wi-Fi and a 2G fallback.
The conclusion Thirteen sensors in one box. In the United States, buy it as a Wi-Fi alarm: its 2G fallback has no network to join.
This kit is bought on one number: ten door and window contacts, three motion detectors and a hub, in one box.
Coverage. An alarm that reports the opening of a door is more useful than one that reports a person already inside, and ten contacts covers a normal house with spares left over. And contacts get moved, lost or broken, so spares are not waste.
TUGARD states Wi-Fi with a 2G GSM fallback. A second path that does not depend on your broadband is exactly the right idea — an intruder who unplugs a router should not silence the system.
But the major American carriers have already switched 2G off. Here, that makes this kit a Wi-Fi alarm with a modem that cannot connect, and the fallback you paid for does not exist — not one day, but today.
Any standard, any certification, any grade. This is a consumer kit sold on contents, and this page reports it as that.
Besides the hub, the sensors and the siren, the box holds three RFID cards, two remotes, an SOS remote and a doorbell button. Control runs through the Tuya app, with Alexa and Google Assistant; alerts arrive as notifications, texts and GSM voice calls, and the first 40 detectors can be named. It mounts with the supplied screws.
A house with many openings and a modest budget, whose owner is content with Wi-Fi alone.

In the United States, no. The major carriers have already switched 2G off, so the second path this kit advertises cannot connect at all. Where 2G still runs — which is no longer here — it would be a genuine second path when broadband fails. Read the cellular fallback as absent before buying on that basis.
Count the doors and windows somebody could open from the ground. Many houses come to six or eight, so ten leaves spares — useful, because contacts get moved, lost and broken.
The figure is usually quoted at one meter and falls away quickly with distance. Indoors it is genuinely unpleasant and will wake a household. Across a garden it is a noise rather than an alarm, which is why outdoor sirens are a separate product.
