How to choose home security system?
I’m not an expert, but I’ve heard that ajax has a decent mobile app. Doesn’t it show the charging level in the sensors? It seems to me that it would be much more convenient to change the batteries in case of something. By the way, the same thing happens on the iPhone when you connect your Airpods. Why not check if Ajax has the same what in the application? I think that it is worth reading more information on the sabzh on the official website of the brand or asking for help from the technical support staff.
If you want to choose a reliable security system for yourself, then you should try to read about wireless ones. For example I found a website https://ajax.systems/, which describes in detail all the advantages of wireless security systems, cameras and sensors. By the way, I installed this system in my house and was surprised at how easily they are mounted to the walls due to the lightness of the material. Also, all sensors and cameras can be easily controlled via the smartphone screen. This is very convenient.
