Overview - W1

KR-X1 (W1) is the entry level box and probably the most common (the K7 is the top level unit). This box allows communication between you and it through either WiFi(2.4Ghz only) or PSTN(eg your phoneline).

It has a W1 app on both the google play store and apple store which is how uses program and setup the device. You must setup a free account with Kerui/Securi in order to use the app.

All Kerui devices communicate with the accessories (eg PIR, doors sensors etc) around the house/office via 433Mhz frequency generally speaking you can use any 433Mhz PIR, door sensor etc to connect with W1 as long as it is on the 433Mhz frequency.

This box like most Kerui alarm units have both their pros and cons, but by comparison to what else is available in the self managed alarm systems with all it's little annoying problems it is still the better of the other manufactures.

If you are new to Kerui and looking at the W1, you will find many reviews around slagging the unit off as 'doesn't work', this is true and not true. The unit will probably throw you a couple of curve balls when you are trying to set it up which is where people get stuck and give up.
