I want to purchase a DIY wireless home security system. For the moment, I do not want to pay a home monitoring service and prefer to be informed of my alarm status via the Internet (WiFi and cellular) and text messages.
The main entrance to the house is a steel gate. Not sure if a sensor exists for this type of entrance. I have 3 solid wood doors, 1 aluminum door with window, many aluminum horizontal louver style windows and a couple of glass horizontal louver style windows.
Also, I have an indoor cat.
I wanted some input on what types of alarm systems and sensors you guys recommend for this setup to work and I can install.
