Koogeek Home Security System Wireless WiFi Zigbee Alarm Kit, 24/7 Monitoring-No Monthly Fee, Alexa/Google Assistant, App Control with Gateway/PIR Sensor/Door Sensor/Temperature and Humidity Sensor

I purchased koogeek home security system, product delivered as a opened box, it looks like used one. but I tried to install it even though it looks like opened box and used. I don't really care about opened box. also I didn't want to order another one. it seems like a good price for the home security system. I spend 2 hours to install the home security system, it was very difficult to install and finally after installed all device separately it was insensitive enough as a home security system I don't think it works at all

If you think that this will protrct your home or office you are wrong! Only Window sensor is sensitive. Thermal and PIR just useless. So I bought 2 boxes and now I should just throw them out!Also product materials are very cheap!
