These days with the technologies so advanced, we can get a home alarm for quite a low price that works. I found this Tuya home alarm for $36 with all the sensors. The Tuya App works perfectly. It works well enough for us to feel safe leaving home.
These days technologies have been improved so much and the price of the products have came down a lot. I got a Tuya PTZ autotracking WiFi camera for $36. It’s quite easy to install and it works quite amazing.
