Smart sensors
Aqara, Shelly and Meross sensors for doors, motion, smoke and floods are great for comfort and automation: the light turns on when you walk in, you get a notification if water leaks under the washing machine. You can set them up yourself in minutes.
The Ajax alarm system
Ajax is a professional wireless alarm. The hub has a backup battery and SIM card, so it keeps working without power or internet. It has loud sirens, keypads and outdoor detectors, and can be connected to a security company.
When to choose which
- Apartment, comfort and peace of mind: smart sensors with a hub.
- House, holiday home, shop or office: an Ajax alarm system.
- The best of both: Ajax for security and smart sensors for automation. They work separately, each in its own app.
Don't forget smoke and water
Smoke and flood detectors are the cheapest insurance there is. Put a flood sensor next to the water heater, the washing machine and under the sink.
