Typically the front entrance door is fitted with a concealed door contact backed up with sensors in each of the ground floor rooms, these can be set up so they pick up your pets. This completely covers all access points into your home. If any upstairs windows are easily accessible from a low roof or extension then we fit sensors to these, which detect the window being opened or the glass being attacked. When set the alarm gives you full night-time protection but still allows you full access to all of the upstairs rooms.
