OK so maybe the Ring and SimpliSafe home security systems are a little out of your price range.
There are less expensive options that will still give your home and family protection. One option is the home security system from X-Sense.
The kit includes one base station, four entry sensors, two motion sensors, one remote control and batteries.
The system can be easily set up by plugging in the base station, connecting to Wi-Fi using the remote or X-Sense app, then putting the sensors in the areas of the most need.
You can receive notifications on your phone while away. You can also change alarm modes and monitor your devices on your phone.
Also works with Alexa.
