Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to install window sensors in your home [title] Choose which windows in your home you want to make part of your home security system. [step] Buy one sensor for each, after confirming that a particular kind of sensor is compatible with your burglar alarm system. [substeps] You don't need to cover all your windows.

Ending1: Windows that are plainly visible from the street, and windows up off the ground floor, usually don't need a sensor. Neither do windows that are too small for a burglar to fit through. Ending2: Installing windows under the front door is not required. For the purposes of this article, open the doors and windows in your house and make sure that you can see outside. Ending3: But you may want to still protect your family from other windows installing in your home as well. Consider locking cameras that collect light but can go inside your home from outside at night. Ending4: You don't even need to cover the entire home, even if your burglar alarm system is particularly large or works with more than two monitors. Ask for confirmation before installing any sensors in each window.
