What it does

This wireless burglar alarm system tells you what is happening at home while you are away: an armed door or window opens, the siren sounds at up to 120 dB and its red dome flashes, and your phone gets a push alert at the same moment. The 65 mm round siren sits on a shelf, draws power from a DC 5V 2A port and joins your 2.4 GHz WiFi so the Smart Life app can report to you from anywhere. It ships direct from China, so you pay less than branded alarms cost in local shops.

The siren is a 65 mm round unit with a red flashing dome that sits on a shelf or table. When a detector you have armed trips, it sounds at up to 120 dB, the dome flashes, and the Smart Life app pushes a notification to your phone. Arm the whole house or just part of it and see the alert wherever you happen to be. The unit is CE, FCC, ROHS and WEEE marked.

Set-up starts at the siren. It joins your 2.4 GHz WiFi on the Tuya platform, then you pair it with the Tuya/Smart Life app and add the battery powered 433 MHz sensors and key fobs one by one. From there you arm, home-arm or disarm from the app, a fob, a timer, or by voice through Alexa or Google Assistant. Home-arm mode makes the dome flash without the siren sound. Disarm mode leaves only the SOS alarm active. As a wifi burglar alarm, only the siren talks to your router: the sensors and fobs talk to the siren over 433 MHz radio, so they work without a network connection of their own.

It suits a house or flat where you want to know when a door or window opens while you are away, and where you want to add detectors room by room up to 24 of them. It does not suit a spot with no USB power nearby, because the siren runs from its DC 5V 2A port. It also does not suit anyone who needs the sensors and fobs to run over WiFi, since those use 433 MHz radio.

Ships from China with tracking. The estimated arrival range for your country is shown next to the price.

  • Know what happened at home while you were outThe siren sounds at up to 120 dB and the red dome flashes as soon as an armed detector trips. The app pushes a notification to your phone at the same time. You can check the house or call someone you trust instead of finding out hours later.
  • Cover every door and window on one hubThis home alarm kit pairs the round siren with a door/window sensor, and the hub holds up to 24 wireless detectors and 8 key-fob remotes on 433 MHz radio. Add PIR motion sensors, more door/window sensors, fobs or a smoke detector room by room as the house needs them.
  • Arm it from a phone, a fob or your voiceYou arm, home-arm or disarm from the app, from a key fob, on a timer, or by voice through Alexa or Google Assistant. Home-arm mode makes the dome flash without sounding the siren. Disarm mode leaves only the SOS alarm active.
  • A small siren that sits on a shelfThe siren is 65 mm wide and 35 mm tall. A DC 5V 2A power port sits on its side next to an ON/OFF slider and a RESET pinhole, so set it on a shelf or table near a USB power source and pair it in the app.

  1. First time I've bought this system and so far I'm satisfied. I have three 433mz infrared detector sensors that connected without any problem. The only thing I'm suddenly not satisfied with is the battery, which stopped working in less than a week.

  2. Very good system, turned on and tuya app sees it right away. Easy to pair with any remote and magnetic sensors. Very loud siren, perfect for additional alarm in the house. I’ll put one in every room.

  3. excellent product. and it does what it says. The only detail I still haven't figured out is why it sends me messages every minute when it's powered on. but everything is excellent and the alarm has a good volume

Questions

Will it work with my WiFi and my phone?

Yes. The siren joins your 2.4 GHz WiFi through the Tuya/Smart Life app. The sensors and key fobs connect to the siren over 433 MHz radio, not WiFi.

Can I control it with Alexa or Google Assistant?

Yes. You can arm, home-arm and disarm by voice through Alexa or Google Assistant, as well as from the app or a key fob.

Does the siren need to be plugged in?

Yes. It runs from the DC 5V 2A micro-USB style port on its side, with an ON/OFF slider next to it, so place it near a USB power source. The sensors and fobs are battery powered.

Is it hard to set up?

No. This wifi home alarm system pairs with the Tuya/Smart Life app over your 2.4 GHz WiFi, then you add each sensor and fob in the app and arm from the app, a fob, a timer or by voice.

How many sensors and remotes can it handle?

Up to 24 wireless detectors and up to 8 key-fob remotes. The kit configuration is a door/window sensor, and you can add PIR motion sensors, more door/window sensors, fobs and a smoke detector.

Why does it ship from China?

We buy from established suppliers in China, and they ship your order straight to you. No local warehouse is why the price is lower. The trade-off is time, so you see the estimated arrival before you pay.

Will I pay anything when it arrives?

Possibly. Import duties and taxes for United States aren't prepaid yet, so the courier may collect them on delivery. Nothing is added to our price at checkout.
