KERUIW18 Only 2.4G WIFI GSM Wireless Basic Burglar Security Alarm System DIY Kit for Home Apartment Auto Dial,APP Control,Not Support Google&Alexa

This alarm is very easy to install and set up. I like the text alerts for activation and the remote access via the app. the sensors are again very easy to set up and the sounder is very loud i have set this up in my shop with the sounder mounted inside the shop it is so loud you can hear it outside even with the door closed. My only complaint is the buttons on the remote control are very sensitive so when this control is in my pocket it keeps setting the alarm off its almost like you only have to breathe on the button and it activates. Just an update i am still happy with this alarm having used it for a couple of years but there are issues the main one is the sensor batteries only last a couple of months and there appears to be no warning either on the panel or via the app that the batteries are going flat. I am now making a power supply to power the sensors via cables as these really dont need to be battery powered. fortunately the door contact sensor requires a 12v supply which i can pick up from the automatic door operator as this sensor is mounted on an automatic door. the PIR sensor require a 4.5v supply these quite happily work on a 5v supply so i have powered it from a cheap usb adaptor. I would recommend other users of this system do the same otherwise it will cost a small fortune in batteries.

Works well enough and for the money it really can't be faulted.

It's a okay alarm, install is easy but frustrating and took alot of research online to find out how to connect it to wifi but when it is it works well but after 2 months of been installed the wired siren has stopped working completely. It's good but quality is not amazing at all

Once set up is a good little system could not get the SIM card working but works great of WiFi

I have had this for about 6 months now. On the whole its very good and does what it says. initial setup is easy enough and all the parts work well. The worst feature is the remote key fob. This can drive you mad...... It has a panic button that is VERY easy to trigger. put on key ring so you can easily disarm when returning home and since the button is proud of the surface even putting the keys in a pocket will often trigger the alarm siren. This is very bad news when trying to leave the house early in the morning without waking the late sleepers. also rather annoying is the way the phone app defaults to sending an sms to control the alarm. fine if you have a phone sim card in the alarm. you can disable the sms communications but it does not enable wifi control via the main app which just stops working. you can still arm/disarm via the phone app using the network connection but only by a round about route. go to the device list you should see something like W180A0B LAN online > . click on that and you get the device menu and at the bottom are some arm/ disarm buttons. if someone knows a better way then please let me know.
